Our Team


Here is a team of experts that was put together from real and personal wellbeing struggles. The team works in unison to help people achieve their maximum potential in life through natural remedies like hormones, peptides, IV infusion, and personalized supplement optimization. This group of doctors and care coordinator specialists had some real dysfunction in their lives but were able to regain their health and vitality in the process. They bring cutting-edge solutions to help patients restore their sex life, energy, focus, weight-loss, physical health status, and restore their sense of youth once again. Once they’ve dialed you in, they like to call that process of achieving this re-invigorating solution the feeling of awesomeness!

Dr. Amy Wecker M.D.

Female Medical Director – Infectious Disease & Hormone/Peptide Specialist


She is a board-certified internist and infectious disease specialist. She completed her internal medicine residency at St. Luke’s-Roosevelt Hospital Center in Manhattan. This was followed by a fellowship in infectious diseases at SUNY Downstate in Brooklyn. She then moved to sunny Fort Myers, Florida. It was here where she became a partner in a large private multi-specialty group, practicing inpatient and outpatient medicine.

Amy loved her job but wanted to move to Miami, so she opened her own practice with a focus on health and wellness and now has joined our team as our medical director. She is committed to the prevention of chronic disease via the reduction of inflammation associated with aging. She is currently completing a fellowship at the American Academy of Anti-aging Medicine, studying regenerative, preventive, and holistic medicine, as well as the benefits of herbs and supplements to slow down the aging process.

Dr. Wecker not only brings all her expertise to treat patients with all types of conditions but also adds the female perspective to our practice. What we love the most about Dr. Amy is the fact that she has a unique and holistic approach to health. She is also an avid practitioner of yoga, applying all of her knowledge to her own health and wellness.

Michael Bertonatti

Clinic director & founder


Michael’s facility has been in practice for six years, helping patients attain optimal health without using the conventional form of medicine. From his awful erectile dysfunction experience, he has ever since deep-dived into the research behind hormone optimization therapy, peptides, and functional medicine clinical research. He found a whole other natural realm of remedies that could restore youth, health, and vitality for patients like himself. He does not just manage symptoms using natural products but apply the principles of “molecular makeup modifications and biochemistry solutions at its finest.” In other words, he focuses on finding and correcting the underlying root causes of imbalances within the human system. If there is a problem downstream, he looks upstream to see the cause and effect of the problem. Managing the practice and working with patients, his team of doctors creates an algorithm to demonstrate the underlying health issue and where it all commenced. Michael always preaches to patients, “The food you eat can either be the safest and most powerful form of medicine or the slowest form of poison.” For the last five years, he has attended with his team every conference, webinar, or workshop he can get his hands on in preventive medicine solutions. He and his team are continuously upgrading their protocols with advanced education in personalized hormone therapies, peptides, IV infusions, supplements, and dietary lifestyle modification habits.

Eric Greene


Eric Greene is known for being an aggressive and competitive tech nerd. Starting as a child he could never get enough of tinkering with or building things in technology. After helping a startup become a roaring success, Eric was beyond addicted to building things and didn’t mind 3 monitors giving him a bit of a sunburn – luckily today monitors don’t do that anymore. Technology allows us to aim far beyond our reach, and that is fundamental to Eric’s core. Obsessing with maximizing the user experience and minimizing the need for human touch, Eric believes this allows us to always reach further and further. Why aim for the sky when the stars are so much brighter??? Eric isn’t just about maximizing growth though, he actively and eagerly is a member of his community and deeply believes that when we are the best versions of ourselves we can contribute to our families, friends, and this world to the best of our abilities. Until somewhat recently, Eric struggled with weight issues his entire life but has found a better path and adamantly wants to help others find whatever their best path is as well – Medical Health Institute is the perfect opportunity to help patients find their best way, whatever that may be, regardless of how long or what they have tried in order to better themselves. Eric leaves the science and service portions of the business to our experts and wholeheartedly focuses on simplifying technology, not just making it do as much as it can. Beyond growth, technology should help enhance our lives, not complicate it.

Daniel Sanz

Patient Care Coordinator – Wellness & BHRT Specialist

Daniel has been actively involved in the bio-identical hormone replacement therapy field for over eight years now and is extremely passionate about health, nutrition, and wellness. He was instantly drawn to functional medicine and the benefits provided by this unique medical approach, where everything administered is natural and recognizable by our bodies to respond at its optimal best. Today, Daniel works with patients, helping them optimize their weight goals, exercise routines, mental well-being, and improve their sexual performance. He is continuously reminded and driven by the life-changing results and personal stories of his patients. Daniel is an attendee and participant of anti-aging conferences like the “A4M”, and keeps his knowledge and understanding of functional medicine up to current date. He has witnessed for himself and patients what the slightest hormonal imbalance can do to a person and believes that no one whether man or female, should have to endure these age-related conditions. Daniel does not only preach good medical jargon, but he lives, eats, breaths, and walks the walk when it comes to his health. He is certain that under the doctors’ supervision and his personal guidance, the patients he coordinates are in the best hands they can possibly be, and he is confident he can help any individual restore their health, youth, and become once again the younger version of themselves.

Moises Martinez

Patient Care Coordinator – Wellness & BHRT Specialist

Moises is a retired lieutenant police officer who does this profession out of sheer pleasure. He has been a hormone replacement therapy patient for over 10 years and in the process of retirement, decided he would enjoy doing this for fun and to help others. He preaches that hormone replacement therapy should not be considered without a complete understanding of how all the body’s hormones interact with each other. If one is altered or deficient, it will affect the actions of all of the other hormones in your body. The hormonal response of an individual is as unique as its fingerprints. How one responds to hormone replacement therapy is related to genetic profile, the condition of your health, stress level, nutritional supplementation, detoxification, and what you eat. All the hormones in the body are designed to work together. However, one size does not fit all, and that is why it is imperative that we customize each treatment for each patient. At our Hormone Replacement Therapy clinic in Miami, each patient receives comprehensive hormonal blood work with the right doctor to evaluate and prescribe. In addition, they will receive the best wellness coordinator possible to convey to patients “in layman’s terms” everything they need to understand and know about their biochemistry. It takes serious experience and knowledge to get the job done, and I am more than confident that from my experience, and with the knowledge of the Medical Health Institute, any patient cared for under my watch, is in the best hands they could possibly be.

Janik Brisbane

Patient Care Coordinator -Wellness & BHRT Specialist

From his life-changing results, he got a keen interest in this field of medicine to help others achieve the same state of health and has become a hormone-peptide care specialist. He’s been heavily trained as a health professional to help manage patient care under the doctor’s supervision. He monitors and coordinates patients’ treatment plans, educates them about their condition, evaluates their progress, keeps them accountable for their results, and encourages them to improve their wellness journey. Janik’s medical knowledge, attention to detail, critical thinking, decision making, and relationship building through empathy with patients are the type of details that compelled us to bring him on board the MHI team as one of our very best health specialists.

I’ve been a personal trainer for about 8 years now, and have the knowledge necessary to take your physical health to the next level.

My fields of expertise are weightlifting, core strengthening, sport athletic performance, boot camp training, TRX workouts, plyometrics, calisthenics, compound functional training, interval training, and super-circuit training. I create customized diets, meal plans, and exercise programs specific to your fitness goals and fitness level. I have priceless knowledge in exercise physiology, nutrition, weight lifting, weight loss educational tips, and easy/simple diets! I’m extremely confident about what it takes to lose or gain weight. Having a body classified in the endomorph category, nothing has ever come easily to me, and my weakness of being overweight became my greatest strength! By eating delicious nutritious meals and maintaining a steady and effective workout regime, I now have the core look of a fitness model, and I consider myself to be in the greatest shape of my life. I once read a quote that has kept me in my tracks and has helped me surpass my fitness goals that say “Don’t relax your efforts, otherwise, it will take you a long time to achieve what you’re after.”
