Originally from Milwaukee, Wisconsin, Andrew Gerken, M.D. grew up in Corona del Mar. It was in high school following a sports injury that he decided to pursue medicine. “I went to a physician in Los Angeles and he said he’d have me back running in a few weeks. I just trusted him and believed he’d be right. Then the idea hit me that would be the greatest thing to be able to help others the way he helped me,” he commented. “I really enjoy the practice of medicine and have fun because I take the time to get to know my patients. You don’t just treat the body part; you’ve got to know what the person is about.”

Dr. Gerken developed a new approach to treating calcaneus fractures. In addition to treating all orthopedic conditions, he has special expertise in ankle arthroscopy and fixing chronic ankle problems that have not responded successfully to treatment.

Dr Gerken served as team physician for his old alma mater, Corona del Mar High School for 20 years. In addition, he was an assistant clinical professor in orthopedic surgery at UC Irvine from 1999 - 2007. Dr. Gerken lives in Newport Beach with his wife and three daughters and enjoys running, tennis and golf.
