Dr Harms entered medicine because of a desire to help people. He enjoys the direct contact he has with his patient's in the family practice setting because it allows him to get to know his patient's on a more personal level. It also allows him to help improve his patient's quality of life through preventive care.

In his free time, Dr Harms enjoys spending time with his family, playing golf and outdoor activities.

Dr. Harms was Chief Resident of Family Medicine at UCI Medical Center.
