    Dr Kang exceeds my expectations again and again! I've been type 1 diabetic for 49 years. She is by far the best endo I've encountered counted over the years. Back office support however is poor. Clearly they have too much paperwork on their hand and not enough head count follow up on chart notes requirements dictated by Medicare. I often need to contact the back office two or three times to get my DMV descriptions filled. Clearly she requires additional support in the back office.
