"I know it sounds cliche, but I wanted to get into medicine to try and make a difference in people's lives" says Dr. Sheen

Along with three uncles and a cousin all in medicine, young David was greatly influenced by his grandfather, an orthopedic surgeon. "My grandfather is currently semi-retired but still sees patients and enjoys it very much. I hope to continue working with that level of enjoyment for as long as he has. He is an inspiration to me. I believe once you develop a trusting relationship with a patient, it is very rewarding to see how a doctor's care can influence their health for the better." Besides family medicine, sports medicine and pediatrics are areas of special interest for Dr. Sheen. He has regularly volunteered his time as a guest educator in Northridge elementary and middle schools along with being a football team physician.

In his spare time, Dr. Sheen enjoys jogging and spending time with family, friends and his French bulldog, Mashimaro. He likes watching football, but claims basketball as his favorite sport to play and watch. As an avid reader, he is a fan of murder mysteries.
