About
Having come from a long line of physicians, the choice to become a doctor was an easy one for Dr. Kazenelson. The question was what specialty to pursue.
I’ve always had a fascination with medical science. As I explored different medical paths through my training, I found I was equally fascinated with the tremendous amount of knowledge required to keep up-to-date over the broad spectrum of primary care medicine. These factors were key to my decision to choose family medicine. I am dedicated to providing my patients with the latest in evidence-based medicine, great communication, compassion and understanding. I get great satisfaction when a patient tells me they finally found a doctor who will listen to them.
Prior to joining MemorialCare Medical Group, Dr. Kazenelson was in practice in Orange County for 8 years. Having grown up in San Clemente enjoying ocean activities, he still loves to spend time on the weekends surfing and scuba diving.

A Doctor Who Explains and ListensI highly recommend my primary care doctor. He takes the time to truly explain things in a clear and understandable way.
