Mark Musco



Primary Care


Mark was drawn to family medicine for the relationship and connection with his patients. The passion he has for listening to and advocating for his patients is what drives his love of medicine. Mark is the co-founder of Diablo Family Physicians with his wife Dolores, with their mission being to treat patients like family and provide the best care possible for the community. Mark earned his MD from The Chicago Medical School (where he and Dolores met!) and completed his residency in family medicine at the UCLA School of Medicine affiliated program at Ventura County Medical Center. He is certified through the American Board of Family Medicine. When not caring for patients at the practice Mark can be found hanging out with his two boys and Dolores. If not with them he will be on Mount Diablo on his Mountain Bike!
