GREAT local resource. My family and I have been using South Coast Medical group for many years. They have been outstanding in making us feel like a priority. I especially like their flexible hours. I’ve gone in to the office for a cold, sleeping problems, nutritional counseling and my yearly exams. The staff is always attentive and knowledgeable. I can do lab work and sometimes get prescriptions all in one visit. It is wonderful to have such a valuable resource, right around the corner! I highly recommend this group.


Great Experience! I visited South Coast Medical Group in June 2010 and had a VERY pleasant experience starting with the receptionist moving forward to the nurse and physician. I was seen in a prompt manner and this office doesn’t even schedule appointments for sick visits. In the past, I have had scheduled appointments with other physician’s offices and had to wait twice as long. So this was a nice surprise!! The nurses were very competent and understanding. The physician was very knowledgeable with GREAT follow up. I would recommend this office to anyone.
