Ernest Castro, M.D.


Family Medicine


“I feel it is a privilege to take care of patients. My philosophy is simple: I treat each patient as though they were a member of my family. I believe medical decisions should not be made by the doctor alone but rather should be a joint decision between the patient and the doctor. “It's your body and you know it better than anyone."
