Stephen S Ehrlich, MD, FACC

Dr. Ehrlich founded Coastal Cardiology of Orange County at the end of 2009. He began his career in Los Angeles at the Hospital of the Good Samaritan, where he helped to develop the ablation program. After three years in Los Angeles, Dr. Ehrlich relocated to South Orange County. He spent 17 years working at Mission Internal Medical Group. While there, he developed the modern electrophysiology programs at both Saddleback and Mission Hospitals. During his professional career in South County, Dr. Ehrlich helped pioneer the development of electrophysiology in the area. He was the first in the county to implant a defibrillator without the assistance of a cardiac surgeon, the first in the county to perform atrial fibrillation ablations, and the first to help construct a dedicated Electrophysiology Laboratory. 

Dr. Ehrlich received his undergraduate degree in Biochemistry at UCLA, his medical training at the University of Vermont, his residency training at USC, and his fellowship in cardiology at UCI. He continues to be active in clinical research. He has served as the Director of Electrophysiology Services at Mission Hospital and has been named a Physician of Excellence by the Orange County Medical Association for the past five years.
