I made my first visit to Dr.Chang a few months ago. She is friendly and professional and non-judgmental. It was mainly a new patient visit, but she was a very good listener and responded well to my concerns that my thyroid condition might need further treatment. After my blood test, the office followed up promptly with the results and a referral that I had requested for a specialist. Winnie, the office assistant, was extremely helpful, as my insurance company had misassigned me to the wrong IPA and primary care doc. She called the company and waited on hold with them while they re-assigned me to Dr.Chang, which was something that she did not need to do. I have real peace of mind with her as my primary care doc and would reccommend her and the staff as providing excellent care.
