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 began a medical career as a medical assistant in her early 20s. During that time, she realized that conventional medical approaches were good at treating symptoms and disease management but not effectively treating patients for optimal well-being. Being an enthusiastic giver, Cindy began deeply investigating alternative routes like holistic and orthomolecular medicine, where she discovered a whole new world. She had the opportunity to work and train under Dr. Amy Wecker, among other top-level practitioners, on the science and art of nutrition, exercise, bio-identical hormone replacement (BHRT), and peptide therapy.

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 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.

James brings over a decade of personal experience with hormone replacement therapy (HRT) and, for the past five years, has worked closely with prescribing physicians to ensure patients understand and successfully integrate their treatment plans into daily life.

Welcome to our upcoming pet department, where we cherish wagging tails and thriving furry companions! Here at MHI, we're not just about human wellness; we're also passionate about the well-being of our beloved four-legged family members. You see, we're not just pet enthusiasts; we're devoted pet parents who deeply understand the love, joy, and companionship our pets can bring to our lives. Our journey into the world of pet health started with Lily, our beloved English Cocker Spaniel. Like all of us, Lily faced her own health challenges which included muscle dystrophy, sarcopenia, and the natural progression of aging. One day, we noticed a significant and persistent limp in her walk. Cocker Spaniels are know to develop hip issues so we took her to the vet. After x-rays, the doctor showed us the image of Lilly's hip which was "hanging by a thread". Like many traditional doctors, this doctor didn't provide us with many options or hope for that matter. The only 2 solutions were either an invasive, experimental, surgery or to strap her back leg to a contraption with wheels. We were heartbroken to say the least. However, we were convinced that there had to be a better option other than resorting to invasive surgery or a lifetime spent on wheels. And this was the beginning of an amazing discovery. Through intensive research we found that, just like humans, dogs can also benefit from cutting-edge approaches like hormone optimization, targeted supplementation, and even peptides to improve their quality of life! Currently, it is common practice to put dogs through early neutering or spaying. Unbeknownst to most, these procedures have significant effects on their hormonal balance, longevity, overall well-being, and quality of life. Naturally, animals have no say in their own care. But, how would you feel if your hormonal balance was purposely disrupted without your consent? To complicate matters further, most pets are fed ultra-processed, high-carbohydrate, and inflammatory diets, which further impact their health. This reality led us to ask a critical question: how do all these factors contribute to the relatively short lifespans of most pets? And then we read about Bobi's remarkable story. Bobi is our shining beacon of hope as he has defied the odds and stands proudly as a happy and healthy 31-year-old dog! His journey has taught us that with the right care, attention, and a dash of resilient canine spirit, our furry relatives can live longer, happier lives. Today, our two ambassadors, Tobby and Lily, serve as living proof of the positive impact of hormone optimization, targeted supplementation, and peptide therapy for dogs. Lily is not only fully recovered and walking again, but they have both shed excess weight, increased their muscle tone, regained youthful energy, agility, and look better than ever. These canine relatives, who also happen to be MHI patients, now extend a warm welcome to our office visitors with love, kindness, and plenty of doggy kisses! With MHI's pet department, our mission is simple: provide your pets with the same level of care, attention, and advanced treatment that we'd want for ourselves and our human relatives. When it comes to the well-being of our pets, no challenge is too big, and no idea is too innovative. Stay tuned as we share our discoveries and insights, so your furry pals can lead lives filled with boundless energy, and tail-wagging joy. We invite you to embark on this paws-itively delightful journey of pet wellness and longevity.
