"I have been a patient of Dr. Comstock's for about 4 years, and he has been the perfect addition to my long-term efforts to "enhance" my longevity in both time and quality. I recently had a comprehensive medical history/blood and DNA analysis completed by an independent Laboratory (TruAge) which tries to determine one's true "biological-age" vs "chronological-age". My result was: at the chronological-age of 79, TruAge determined that my true biological-age was only 64 years! I believe that Dr. Comstock and his very capable staff have been key to this wonderful result. Physically, I remain completely able to do all of the activities (hike/bike/ride motorcycles/fly acrobatic-airplanes, etc.) that I've enjoyed doing ALL of my long and enjoyable life. If you want also be a "longevity-enhancer" I suggest you contact Dr. Comstock for a consultation."

Excellent Review by A.T., via Google

Dr. Comstock changed my life. Balancing my hormone levels after a comprehensive workup via the most cutting edge means literally took my quality of life to a level I had almost given up on ever finding. Energy levels, overall wellbeing, sleep, weight loss and a marked drop in a near lifelong anxiety issue. I feel 20 years younger!

His staff are the most courteous and attentive I've encountered in the medical field. Dr. Comstock took a generous amount of time with me, listened intently and navigated to a clinical approach that no other physician has ever been able to diagnose or even come remotely close thus far. I highly recommend Lifestyle Spectrum and Dr. Frank Comstock!
