About

*Dr. Ah San is currently only accepting patients 6 years and older.

R. Keone Ah San is a certified Physician Assistant. He has more than a decade of clinical experience, with the majority of those years working for one of the busiest Endocrine/Renal clinics in Southern California. As a result, he has extensive experience in seeing Internal Medicine, Endocrine, and Renal patients.

Growing up in Hawaii, he developed an early interest in sports and nutrition. This helped influence his decision to earn a Bachelor’s Degree in Exercise and Movement Science from the University of Oregon, Eugene. Remembering how his childhood pediatrician could always make him feel better, he went on to earn a Masters in Medical Science from the Department of Family Medicine/Physician Assistant Program at Emory School of Medicine in Decatur, Georgia. Today, he enjoys being able to play his part in helping to improve the quality of his patients’ lives and, just like his childhood pediatrician did for him, make them feel better.
