Dr. Chris Renna

Dr. Renna graduated from University of Texas, earned his medical degree cum laude from the University of North Texas Health Science Center and completed a residency in family medicine. In his initial years of practice, he learned that medical school prepared doctors to diagnose disease but did not prepare them to create health.

Dr. Renna decided to truly help his clients improve health, he needed to create an entirely new system and approach.  This was the beginning of LifeSpan medicine.  LifeSpan provides comprehensive and focused medical evaluations specializing in preventing disease, resolving symptoms and improving health.  These programs are delivered through personalized concierge support, access to your medical team 24/7 and exceptional follow up. 

Since founding LifeSpan medicine in 1992, Dr. Renna has maintained a small practice focused on optimal health with two rules. 

Everything is about you.
Everything is about your health.

Over the years his passion and dedication to clients as well as his unique approach has earned him an exceptional reputation as the nation’s premiere preventive medicine provider. He is a published author, popular public speaker and lecturer to audiences across the United States and abroad.

“Dr. Renna changed my life. All of the injuries from my athletic youth were starting to add up and the constant pain from arthritis seemed to be something I was going to have to live with. Since having the injections I have been able to ski..and to live my active life without having to manage pain.”
