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.

He’s smart, personable and he listens and makes notes on what we talked about during the previous visit. He prescribes age appropriate medicines and we talk about possible side effects.

This was my 3rd visit with Dr. Lawrence Ahn over three consecutive calendar years and he continues to be an excellent, exemplary medical provider. Dr. Ahn has a receptive, considerate demeanor, is thoughtful, and demonstrates a broad, deep knowledge base. I could not ask for a better primary medical professional.
