Regenesis​ Performance

Lifestyle and Performance Medicine | Health Coaching | Physical Medicine

Welcome to


Regenesis focuses on optimizing performance and lifestyle factors that ultimately lead to disease and dysfunction. There is an overlap with functional medicine in that we look at root cause of a disease rather than focusing on just the symptoms of a condition or disease. In performance medicine we look at stress and stress mitigation options, improving sleep, improving nutrition and increasing activity to help with overall health. There are many barriers to function that exist and ultimately will create disease. In order to improve quality of life and function, this requires a detailed understanding of each persons metabolic and physical health as well how lifestyle factors and genetic factors then can amplify the metabolic and physical barriers leading to dysfunction and breakdown of the health of the individual. We use data and testing to direct nutrition and nutraceutical interventions when needed for overcoming metabolic dysfunction. We also look for how physical conditions contribute to the dysfunction and impair restorative activities such as sleep and exercise.

Ultimately our mission is to treat the underlying causes of the symptoms and remove barriers to performance rather than to focus on using medications as the only solution for illness or functional barriers. We want to help you build a healthier, stronger and more resilient body. This improves quality of life with lowering the risk of disability and chronic disease states.

Common issues that are addressed as barriers to quality of life improvements:

  • Allergies
  • Cognitive decline
  • Fatigue
  • Digestive disorders
  • Autoimmune issues
  • Male and female sex hormone dysfunction
  • Chronic inflammatory states
  • Insulin resistance
  • Musculoskeletal disorders and injuries
  • Nutritional deficiencies
  • Thyroid dysfunction
  • Concussion and brain injury
  • Weight gain and more...

Our practice has adopted a private-pay model vs billing insurance which places fewer restrictions on the type, scope, and length of care, meaning providers can personalize treatment plans for each individual. An initial consultation is typically 1 hr and follow up appointments are typically 30 minutes.

Meet The Founder

David LeMay M.D.

Dr. LeMay works as a consultant for professional organizations in helping performance and by educating groups in understanding how life style impacts productivity and recovery.


As a former Green Beret for 10 yrs with numerous deployments under my belt. When I left the army in 2015 I was an absolute wreck. I was a shell of my former self having just been beat down physically. I’ve now worked with the team for several years now and the protocol I follow at Dr. Lemay’s direction has been life changing. I’m really not sure where my health would be had I not spoke with these awesome folks. A great big thank you from me and I can speak for my fellow SOF brethren as well. Keep up the great work!

Jessica helped me figure out the “why”to my sleepless nights and helped me discover the key nutrients that I was deficient on. By creating a plan to heal my gut with the right probiotic and nutrients I needed along with a deeper look into my hormones and thyroid levels, it was the puzzle I needed help with and could not find anywhere else. The investment I made in working with Jessica was so valuable. She listened to me and helped me create a plan that I have been able to implement and in turn has me feeling my absolute best!
