About

Lawrence Ahn, MD, attended medical school at Loma Linda University School of Medicine and went on to complete his residency in internal medicine at USC (LA General Medical Center, Keck Medical Center). Dr. Ahn decided to pursue medicine after witnessing how lung cancer affected his father and family from a young age. His fascination with understanding diseases and their management propelled him into the realm of primary care, where he cherishes the opportunity to address a wide spectrum of conditions and intervene before hospitalization becomes necessary.

I want my patients to know that I'm committed to fostering open communication with my patients, ensuring that their concerns are heard and addressed with compassion and attentiveness.

Dr. Ahn grew up in Torrance and Temecula. Outside of medicine, he enjoys playing piano and bouldering.

Doctor Ahn so far is the best doctor for me and my family! Besides being a very smart doctor, the most important thing is having the heart of a doctor. He's very caring, thorough, humble. His goal is not I only to help you feel better but to make you feel better. He may be young in age and experience as a doctor, but his professionalism and concern for his patients brings the best out of him. We trust Dr. Ahn!
