About Us
DEFY Medical

Defy Medical is a state-of-the-art medical clinic that is a dedicated leader and innovator in the field of integrative wellness; offering the best in clinical expertise, education, and clinical research to improve the health and quality of life of patients. ‘Integrative wellness’ describes the practice of treating a patient through an approach that often includes hormone replacement therapies, nutritional support, and lifestyle modifications to help mitigate preventable diseases and reverse symptoms resulting from age-related (or disease-induced) hormone deficiencies.

Defy Medical combines proven treatment models with an emphasis on life quality including interventional hormone therapies, testosterone supplementation, sexual health, weight management, nutrition, and more. Experienced staff and a newly-expanded facility are equipped to treat the full range of patient issues under one roof, with no referrals necessary. Defy Medical introduces a medical facility that offers a comprehensive wellness approach for the treatment of common health problems endured by aging men and women suffering from hormone deficiencies. Unlike conventional medicine, Defy Medical will personalize the individual patient’s care by thoroughly reviewing the multiple systems that make up the whole body to deliver thorough approach toward the diagnosis. 

Established partnerships with key vendors allow the clinic to offer affordable cash-pay services that may often cost the patient less than when using a third-party payor for similar services. The self-pay model allows the clinic to offer affordable access to treatments typically not covered by insurance with more time allowed for quality patient care. Patient access is enhanced through our telemedicine service, allowing patients nationwide a convenient way to receive quality care.

Defy Mission


Our ability to communicate information effectively to both our patients and our co-workers will help us build rapport with that person and allows for fewer mistakes and misunderstandings. It is important that we take the time to listen attentively so we can communicate our knowledge effectively. Effective, direct communication can create a bond with the person we are speaking with. Our patients will benefit from clear communication and instruction so that we can provide the best medical care possible.


Our knowledge will allow us to advise patients specific to answering their questions. If we’re not sure what the correct response may be, medical providers will always advise us on the best course of action for patients and it is up to us to communicate this information to them effectively with clear and precise direction. If we’re unsure on how to handle a patient's concern, a manager or supervisor is always available to advise on how to handle situations that may require assistance or additional follow-up. 


We have found that it is imperative to always review our work before submitting, whether it be an email to a patient or a prescription to the pharmacy; therefore, we have built layers of checks and balances to review and assess the work prior to completion. As policy, we continuously review our processes and protocols to ensure we are optimizing potential and completing tasks efficiently. When change is necessary, we review that process and look at all possibilities to ensure it’s being done the best way possible. When it comes to reviewing with a patient; we maintain dialogue to ensure the patient thoroughly understands the information being relayed. We will not end the call until the patient comprehends the information provided. 

Ensure Satisfaction:

At Defy Medical, we will always strive to ensure patient needs and expectations are exceeded and that provide exceptional patient care. If we make a mistake, we will identify and acknowledge the error and find solutions to the problem. Then we identify ways to avoid making the same mistake in the future. It is our responsibility to communicate effectively and provide follow up when necessary to ensure the patient is satisfied with the level of medical care and customer service they receive from us.

We take pride in our scientific approach to understanding the effects that aging has on the human body. We offer the best in clinical expertise, education, and research to improve the health and quality of life for each of our patients. Many wonder what the term ‘integrative wellness’ means and how it differs from other medical disciplines. Integrative wellness encompasses the practice of treating a patient from a preventative and holistic approach.

At Defy, we strive to gather the entire lifestyle and medical story of each patient before we prescribe any treatment. We go beyond a conventional approach to medicine by understanding that each patient is unique and requires personalized care. Our thorough medical assessments give us the opportunity to deliver a comprehensive diagnosis and a solid solution. Our goal with each specialized approach is to help mitigate preventable diseases and reverse symptoms resulting from age-related (or disease-induced) hormone deficiencies.

Expect Quality from Defy Medical
Our patients can always expect consistent quality with every prescription.

Each batch is tested for potency and sterility by an independent laboratory. Every compounding pharmacy must comply with the regulations set by USP 797 and the Board of Pharmacy of the state in which the pharmacy is located.

Does Defy Medical Treat International Patients?
International Patients mobile

While Defy Medical is licensed to practice and prescribe medication within the United States, we do provide consultations to international patients. In these advice-only consultations, an experienced Defy provider reviews labwork, existing protocols if applicable, and goals, and provides expertly guided recommendations. Many patients then take Defy Medical's recommendations to their local provider for more specialized care.
