About
I will help you be the healthiest version of yourself through fitness, nutrition and harnessing the human body’s natural ability to heal itself.
In order to do this, we must take a proactive and preventive approach to health and wellness. During my career as a hospitalist I cared for patients admitted to the hospital for a variety of severe illnesses and ailments. I spent several years practicing this type of acute care medicine. During this time, I saw firsthand how “traditional healthcare” has failed many individuals. Our current healthcare model is reactive and episodic and spends 98% of it’s dollars on treating patients once they are already sick.
Although I enjoyed caring for patients in their most critical moments of life in the hospital, in my heart I knew I could impact others’ lives and longevity if I had more time to spend with each patient. There was no reason for many of these sick patients to end up in the hospital with heart attacks, strokes, cancers and dementia. Did you know the CDC estimates 80% of chronic diseases are fully preventable?
My goal as a physician is to educate patients to enable them to create healthy lifestyles, by reducing stress and developing informed, mindful nutrition, sleep and exercise habits. Additionally, by utilizing advancements in technology such as genetic analysis and regenerative therapies we can all improve the quality of our life, and as a secondary benefit, extend our healthy lifespan!

Personally, I practice what I prescribe. I enjoy an active lifestyle centered around healthy eating habits and exercise. For 15 years I competed as an amateur, natural (drug-free) bodybuilder. I still train most days of the week. My downtime is spent with my wife supporting her in competition as a brown-belt in Brazilian Jiu-Jitsu. We also enjoy playing with and walking our Doberman and two miniature pinschers.
