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.
SpecialtiesDoctors 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.
