About

Bio

I grew up in a very small town in Florida as the son of a single mother. I initially wanted to be a marine biologist, but got a draft notice. I joined USAF and did research with NASA as I continued grad school in chemistry & biology; my dissertation involved halting aging. I thought that I would continue medical research and went to medical school. As I went through school, I liked everything but especially patients. I loved the battle of disease. I could not decide which specialty to do so I chose Family Medicine and did 4 more years of specialty training so I could do them all. I did surgery, delivered babies, and took care of their grandparents. As I continued in practice there were areas that especially interested me. ADD/ADHD, Alzheimer's, Pain, aging, and Longevity.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.

Family Medicine

ADHD and Autism

Geriatrics

Pain Management

Preventive Medicine
