Embarking on a journey of healing and transformation with Dr. Leon Mellman transcends the boundaries of conventional medicine. As a chiropractor and nutritionist, Dr. Leon embodies the essence of compassion, wisdom, and unwavering dedication. After seeing numerous doctors – without any relief – Joe Riccutti, a family friend, referred us to Dr. Leon and his expertise in 2011. We didn’t know what to expect.
Dr. Leon’s holistic approach, encompassing nutrition and chiropractic care, was not merely about treating symptoms, but about nurturing the entire being – body, mind, and spirit. With boundless energy and genuine care, he delved deep into understanding our father’s ailments, leaving no stone unturned in his quest for healing. The environment he cultivated was not just a clinic but a sanctuary of positivity and hope. While father felt physically exhausted at first, it was followed by feeling physically and emotionally rejuvenated.
Beyond the confines of his office, Dr. Leon’s impact resonated through his Be Your Greatest (BYG) calls. These sessions, brimming with his unparalleled nutritional knowledge specific to your individual Dietary Engineered BYG nutritional playbook, and innate talent, transcend mere guidance. Whether navigating dietary progressions or offering insights into holistic wellness, at home or in the work place, Dr. Leon’s presence extends far beyond the parameters of a traditional physician. From our family traveling to meet and begin this process to Dr.Leon traveling to meet with us and installing the BYG system into daily practice at our parents’ home – in every interaction, we have all jumped in for our families to be their greatest. Dr. Leon radiates warmth and compassion. He has a great sense of humor and an unwavering commitment to the well-being of his patients. He is not just a healer but a beacon of light, guiding individuals towards a life of wholeness and fulfillment. Our gratitude knows no bounds for the profound impact he has had on our lives. Dr. Leon is not just a doctor; he is a true healer, mentor, and friend.”

Christine Trice - Bone Density & immunity
Doc Leon came into my life during a very difficult time. I had been suffering from severe sciatic nerve pain off and on for over 20 years. During this time I was treated by chiropractors, orthopedists, pain management and primary care doctors which yielded some temporary relief for a time but the pain would always return. The pain eventually progressed to the point wheresitting and standing for any length of time was unbearable and I started spending more and more time lying in bed for relief. Chronic pain had taken over every aspect of my life.
Then one day while at work I met Doc Leon’s wife Kim. She saw from the way I was moving I was in pain and started asking what was causing it. We had a conversation about the pain and all the treatments and doctors I had tried and that now I was being told I was a good candidate for surgery at which point she said my husband is a doctor you should come and see him. I asked what kind of doctor and she replied he is a chiropractor. My response was I have already been to several chiropractors and yet here I am still in all this pain. I will never forget what she said “YOU HAVEN’T BEEN TO MY HUSBAND HE IS NOT LIKE OTHER CHIROPRACTORS” !!!! Boy was she right!!!!
This was when my journey with Doc Leon started. When I entered the BYG Campus for the 1st time I had no idea what a monumental life changing event was about to begin. After getting my history and hearing my story along with performing a nervous system scan and xrays he assured me he could help get my pain under control without surgery but never promised I would be totally pain free. I started seeing him weekly and the visits included guided stretching, oxygen chamber time, along with his gentle adjustments and advice on things to do at home to help with pain. I tried to limit my walking or standing time to 15 minute intervals in order to avoid the pain kicking in.
Fast forward about 6 weeks into my journey with him I was grocery shopping trying to get done as quick as possible to avoid pain setting in when I realized I had been on my feet for over 30 minutes and pain free!!! As I continued walking ever so carefully and the pain didn’t come back I found myself with tears of joy running down my face. This was the moment I knew I was going to get my life back.
It is now over 2 years later and I am still in his care with the added bonus of working side by side with him at his BYG Campus. As I observed him interacting with his patients during my early visits as a patient I knew he was the person I wanted to work with someday and now here I am doing just that.
I am blessed to observe and assist him with helping people heal and Be In Pursuit of Their individual healthcare greatness.
I in addition to the way he approaches chiropractic pairing it to different protocols of hyperbaric chamber therapy I am now 8 months into his Integrated Nutritional Program known as Dietary Engineering with my Dietary Progressions BYG Playbook and I am enjoying an astonishing amount of new energy and focus. My inflammation is improved, and I can actually control this thru the correct foods for my body, it’s fascinating I am told my skin is glowing and I have lost a good deal of weight, get to enjoy eating the correct foods for me and find it very fun to challenge in food attempting to build my menu of working foods which has helped me regain muscle tone without feeling hungry all the time. Recently I completed yearly lab test results revealing showed improvement in blood cell counts and as an added bonus tests confirmed my bone density substantially improved as well.
I am certain that with his Dietary program, his hands on care and the vast knowledge he shares with me my health and well being can only continue to improve.
Doc Leon has become so much more than just my doctor but also a very dear friend I love and admire. He has truly become “The Wind Beneath My Wings” and I am forever grateful.

Daniel's Family - military & nfl
Working with Dr. Leon Mellman has been a true blessing for our entire family. My husband, Mike Daniels, and I, along with our parents, in-laws, siblings, and extended family, have all experienced the profound impact of his expertise, particularly in nutrition and bodywork.
Dr. Leon Mellman’s guidance sustained Mike throughout the latter part of his NFL career, equipping us with invaluable knowledge on how to use food as a healing tool through our personalized dietary engineered BYG playbooks.
His innovative approach, including the use of hyperbaric chambers and outstanding pro-level hands-on sports chiropractic work, has not only contributed to the longevity of Mike’s career but has also been instrumental in helping him recover from injuries and his dad using his own dietary engineering nutritional program to win the fight over diabetes and remove side effects from medications we paired that to Dr.Leon’s pro-level hands on care and even saved a few body parts that usually the traditional medical system just says sorry we will have to remove those, not kidding you Mike’s dad just wish’s he would have started working with Dr.Leon before they took one leg but he has fought them off and kept the other because of the work Dr.Leon does and the service he provides…seriously. We are continually amazed by Dr. Leon Mellman’s wealth of knowledge, which he shares with such passion and dedication.
Beyond his professional expertise, what truly sets Dr. Leon Mellman apart is his vibrant personality, love for life, and deep commitment to his family. We adore him for the warmth he brings to every interaction and the genuine care he has for his patients. It’s heartwarming to see him continue his mother’s legacy, positively changing lives through his work. Being Your Greatest !”BYG”
We are eternally grateful to God for leading us to Dr. Leon Mellman many years ago. His thorough in-person teachings, along with the support we received over the phone whenever needed, those “BYG-Calls” then and still do empower us to continue our health journey. We’ve learned how to remove inflammation from our bodies and heal from the inside out, which has been transformative for our overall well-being.
A special thank you goes out to Dr. Leon Mellman and his dedicated supporting cast for preparing meals when asked and supporting us with planning, and shipments etc. throughout this journey over the many years. Their contributions have been vital to our health improvement. We genuinely believe that without healthy bodies, we cannot live life to the fullest, and we know we have our “BYG cheat code” in Dr. Leon Mellman’s program.
Thanks to the comprehensive application of the knowledge we’ve gained, we are better equipped to overcome health challenges and take care of ourselves. We hope that by sharing our gratitude, others will understand the remarkable impact Dr. Leon Mellman has on individuals and families alike. It is with great joy that we contribute this testimonial, and we look forward to seeing how his work continues to inspire and heal others through this first self help book.

Not only do the carefully designed diets assist in enhancing health benefits as a lifestyle protocol regimen I can personally confirm, but docLeons peronal attention and Counselling are also of invaluable benefit.

My goodness where does the time go…
Their work with NFL athletes and media like myself is well-documented. The dietary engineering success of learning how to play the game, integrating this into a lifestyle makes it very fun and practical when on the go.
A realistic approach knowing what foods work best for my individual system, which foods are cell death foods is a critical place that we can make decisions from and how different we all are and the depth of the dietary engineering diagnostics over the years of how our systems evolve is fascinating, being redrawn for my RE-Engineering years later from my initial blood draw the accuracy and result of putting it all into play helps me to keep winning in the game of life and my health. Traveling consistently for the media work then family time being able to rely on my working foods and brands from my menu brings consistency less inflammation which is the result needed with media work. A positive side effect Dr.Leon constantly points out is the ability of my system’s God-given ability “to adapt” its very best to the environments I am around, less sick days to actually almost non at all from traveling for work and play my immune system strength is at its best.
My foundation foods give me that certainty and reliability during these timeframes then when I’m home for a few days I can organize to challenge in a new food or two, adding to my working menu or schedule in a cheat meal or an off-day with “no remorse” knowing exactly how to start back right where I left off using my recovery day protocol,
(it’s a lifestyle protocol I find myself saying…)
I remember Sari saying
& now Dr.Leon to this day – say,
it’s Dietary – not a diet, you know how to make magical food moments happen.
Get right back on your recovery day foods and any inflammation put on my body from having that cheat meal or going off is gone in 48-hours, that’s a magical food moment in it self with digestive food symptoms and lingering physical food symptoms now something of the past, back down to my low scale reading which means weight, seriously this is real.
Did I mention learning about our bodies cleaning cycles, how they only activate when we are in the horizontal position legs up and these specific organs work most efficiently when on your working foods and when we can get into the “HT”horizontal, laying down in this position as much as possible to learn how to calm your mind before actually going to sleep. That’s right if you picked up on this you can actually start losing weight while laying down and you get mentally calm enough to witness a click-in while being wide awake this secret educational piece of technology is intriguing and inside of all of us…Dr.Sari brought it all together for teaching us how to map-put your cleaning cycles, it’s a paradigm shifter.
What you thought you knew about conventional nutrition does not apply here.
Learning about the 4-specific cells that interact with food structures to your prostaglandins and other educational teachings “your BYG-Edu-Calls” along your journey with Dr.Leon at your own speed as I did and revisit it again and again over the years.
Becoming your very own dietary engineering is self-empowering, invigorating, game changing as life goes on giving us the tools to interpret our individual systems then make conscious decisions to replicate consistent dietary success that shows up in so many areas of our lives.
Being healthier, on less medication to maybe none at all, this is the conversation with so many I have surrounding Dietary Engineering with Dr.Leon Mellman no matter which professional and what industry we work in.
Witnessing the many professionals to elite level athletic human beings extending their careers just as Dr.Leon’s BYG system with dietary engineering has extended my career and longevity in life in addition to helping many of our family members get well and stay well. To be our greatest.
Dr.Leon through out the years, exemplifies a Gold Medal Olympic level of follow thru and follow up, it is like nothing else I have experienced before just like a 5-star concierge desk, I chuckle as I draft this because I am reminded time and time again with some of the overwhelmed healthcare systems in our great nation you can not always get to a doctor as quick as we would like and then someone on my team or my lovely wife Dorothy reminds me, just text Dr.Leon my Pro-Doc and even better, a dear friend only by their genuine caring for the whole person, true well-being, our conversations, these BYG calls are very special to myself, my family and the philanthropic work in community.
Dietary Engineering is your first step,
The second step, receiving Dr.Leon’s guidance thats two generations deep.
The time in counsel with Dr.Sari was extraordinary insight. An angelic woman of time, way ahead of her time. An asset we hold dear to our family.
Dr.Leon his old wise soul will intellectually stimulate you, learn and laugh out loud as his vivacious spirit up lifts you teaching you along the way on your BYG calls. Dr.Leon is carrying the torch.
I am proud as a participating patient.
No doubt that Holy Spirit above is proud of Dr.Leon guiding people into being their healthiest greatest versions of themselves. Truly a work of ministry. This I know well.
2nd to none is the experience waiting for you.
I know and trust if you’re willing to put the work into yourself, the healthiest greatest version of yourself is right around the corner.

Joy Freeney - NFL MOM
My name is Joy Freeney & I’m delighted to be included in Dr. Leon Mellman’s book:
Dr. Leon Mellman has been a true family friend for the past 20 years and more.
I got to know him through his mom, the late Dr. Sari Mellman. She was an excellent Nutritionist who began working with my HOF son, Dwight Freeney, in 2002. Dr Leon & his mom were an integral part of my son’s successful football career. As a team, they were responsible for helping him with his Nutrition and his Chiropractic care. Eventually, me and other members of my family were able to experience the same level of care from – which we benefited tremendously from. To visit to Dr. Leon Mellman’s office is to experience a positive and healthy environment which allows each patient to feel emotionally whole.
Attending the BYG calls that Dr.Leon hosts is another experience on its own – the guidance, his innate natural born ability, and his talent that gets right between your ears, then into your life – from learning the correct foods for you to other aspects of his BYG system (at home or wherever you might be) all help keep you in pursuit of being your greatest.
I highly recommend this BYG-book, that you get involved with Dietary Engineering and go hands on with Dr.Leon because there isn’t another on the planet that captures the skills of a Chiropractor and Nutritionist who transforms the lives of so many, especially athletes like my son Dwight Freeney.
Katy Sade - things you can control & energy
Always happy to help my friends and family when I see my advice will make a difference ✨
Have never coveted anything and not shared so I would be ahead of others, it’s not in my nature, I believe in this life journey we all have a path how we navigate that will decode our accomplishments and success 💫
Dr.Leon does just that. Your choice of how you wish to start…
Dietary Engineering this magnificent nutritional diagnostic protocol his mother pioneered, developed & founded initially to save Leon’s life. When you learn How To Play the Game with your programs challenge lists finding foods compatible to only your system things that have been bothersome to you become something of the past…. You get control of this with consistency and certainty learning to trust these foods that produce the same result day to day. Making magical food moments happen, Leon says this all the time, it makes me smile to this day. 15 years working with Leon, taking BYG calls counseling performance of life.
Or choose to go visit with Leon at this very special place they call BYG Campus. Experience his hands on care, a different level of spirit and talent in this adjustment then add oxygen chamber therapy, a wonderful pairing.
This relationship with Dr.Leon and his NYG System started with saving my daughters life tour what Dr.Leon called reverse engineering to reengineer her female hormones which had some challenges at a young age and medications involved way to long but when she got on her correct foods for her system thru her own dietary engineering diagnostics it was only a matter of time for her system to reach a level of cellular correction to food structures and things she was dealing with all became something of the past…
a Win Win for my little girl then, who has grown up healthier and stronger in her
well being conscious to food the other ingredients sometimes involved that are misleading and the marketplace.
We all have the potential of reaching many heights and success, our input in the universal energy will outline our journey, the correct foods equals the correct cellular energy and that path with Dr.Leon as your guide.
Being Your Greatest is a spirit energy that lives within all of us, feed it correctly and
Be Your Greatest ! 🙏🧿🙏
Naima Walker Fierce - A mom's wellness plan
Dr. Leon has been a transformative force – not only in my health, but in my life.
Before working with Dr.Leon I worked with a famous medical doctor in New York City who is known for his nutrition plan and subsequently with a well known MD in Washington, DC who incorporates healing into her practice. I share this with you because I had marginal success with both the NY and DC doctors that were mainstream or marketed everywhere but what I learned is that it was not specific and in-depth to my individual system . However, it was not until 2022, when chronic joint pain and fatigue caused me to reach out to Dr. Leon that my true journey to health began.
In society, we so often speak of gifted artists, gifted athletes, gifted surgeons, etc. Dr. Leon is the only person whom I have ever met who is able to use his gifts as a medical practitioner and, arguably, as an artist, in overlapping and highly complimentary modalities. I have been seeing chiropractors since I was a child – Dr. Leon is hands down the best chiropractor for me and four members of my chiropractor-heavy family have ever worked with. Dr. Leon’s insistence that I incorporate hyperbaric oxygen chamber sessions into my weekly schedule and for me to keep my BYG postural conditioning as a hygiene focus surrounding when I travel into town for his adjustments reinforces they last longer protecting my frame my joints and my mind with that BYG athletic spirit mentality while working on my entire well being. Feeding my system its correct foods has resulted in extraordinary improvements in my health. More significantly, Dr. Leon’s proprietary, individually designed immunology based nutrition program known as Dietary Engineering, initially developed and founded by his mom, Dr.Sari Mellman P.h.d
is revolutionary and life-saving for me.
I am grateful Dr.Leon is carrying this torch and has kept his Dietary Engineering going.
Without Dr. Leon’s wisdom, commitment, patience and guidance over the last 18 months, I know that I would still be sick,
in chronic pain and, most devastatingly, in constant fear of the chronic diseases that kill most Americans – heart disease, Alzheimer’s disease, cancer and Type-2 diabetes.
Due to Dr. Leon’s all-encompassing approach to health and life, he calls and teaches as “The BYG System” not only has my health been saved, I have a proverbial “new lease on life” because I no longer fear any disease because Dr. Leon has not only given me the tool-kit to prevent disease, he has given me the ability to fight any disease that may come by way someday, head-on, through my own immune system. Being My Greatest !
Dr. Leon is my chiropractor, nutritionist, friend and brother by another mother. He is a true gift from God and a blessing to everyone who meets him, and your lucky if you get to know him thru BYG counsel particularly those fortunate enough to call him Doctor!

Ralph Byer - inflammation
Inflammation is the enemy.
Dr. Leon Mellman has the key to defeating it.
I have known Dr. Leon for over 20 years. Dietary engineering and his BYG hands-on approach with sports chiropractic paired to how he teaches us to implement hyperbaric oxygen chamber therapy at home or at BYG Campus and his soft tissue vitamin combing procedure is just a wonder everyone needs to make the time to experience this and then schedule it into their lives regularly. It’s does wonders for me and many others I Refered throughout the years.
BYG – the philosophical spirit that as Dr. Sari Leon’s mom & Dr.Leon say lives within all of us and is there ultimate goal for each person.
Dr. Sari Mellman P.h.d, The founder & developer of Dietary Engineering.
A custom proprietary program based on your own body – specifically determined through your blood. When following this way of life, because it’s not a diet ~ it’s dietary and becomes a lifestyle from which you make decisions from and gain control of your weight per frame size and over all inflammation thru the correct foods for your particular system. When you choose to add in Dr.Leon’s BYG pro-level hands on system it brings it all together like a super-charger. The inflammation and symptoms become something of the past like in your rear-view mirror. You have the ability to control this, be consistent and stay in-tune. To Be Your Greatest !
Sahar M.Z. - Reason: pregnancy & female hormones
DocLeon and the BYG Family have developed an incredible and unique program that truly helps get to the root of an individual person’s physiology and dietary needs. I struggled with a number of physical challenges over the years, tried numerous diets and medications to curb symptoms, and suffered from issues with various organs in my body not quite ‘clicking in’ to where they needed to be. Sadly, I also experienced a painful pregnancy loss, which was unexplained, and caused a series of other physical ailments for the subsequent year. Something in my body became unfamiliar to me, and both my doctors and I could not place where the issues were stemming from.
I was then introduced to DocLeon’s program. After one month on the BYG program, and with diligent coaching from DocLeon, my hormonal system reset itself and I had my first normal cycle in almost a year. By month two, I was elated to find out I was pregnant again!
The weight loss I experienced was not my primary goal going into the program, but was a positive byproduct that happened organically as my body learned to process foods that were biologically aligned to my cells. I dropped to my lowest healthy weight, and felt great both inside and out!
The program requires trust, consistency and hard work, but once you overcome the mental challenge of making such a major life shift, it is very much worth it! The education of the program alone, alongside DocLeon’s attention and commitment to you as a client,
is what makes this such a successful program. He spent ample time understanding my health history, providing information, coaching me, and suggesting alternatives I could use to cook and eat.
We are beyond thrilled to be welcoming our baby girl to the family this Summer, and are grateful to DocLeon and his team for getting my body healthy again, bringing my system back in sync, and helping me to feel great. Thank you to DocLeon and BYG Team!
