Gregory D. Middleton, MD

Associate Clinical Professor


Academic Profile

Dr Middleton is a rheumatologist, specializing in the non-surgical care of patients with joint and muscle pain, particularly associated with rheumatological disorders such as osteoarthritis.  Dr Middleton went to medical school at Boston University, completed his residency  and fellowship at UT Southwestern in Dallas.  He joined the team at UC San Diego after almost ten years as Chief of Medical Specialties at Southwestern Medical Associates in Las Vegas.

Dr Middleton became a physician out of a keen interest in science and the desire to help patients maintain a satisfying and active lifestyle.  He believes that his clinical wisdom, patience and honesty allow him to make a difference in the lives of his patients.  Dr Middleton has treated many former and recreational athletes who strive to maintain an active lifestyle in spite of certain muscle and joint challenges.  "Staying active in the right way is probably as big a factor in pain as the amount of damage to the joint."

Dr Middleton ran cross-country in high school and was coxswain for the Boston University rowing team.  He currently walks and practices yoga.  Dr Middleton also writes fiction, composes music, plays keyboard and drums and is an amateur chef.
