I was seen on time by my Dr. I had my A1C and blood glucose checked prior to the Dr. seeing me. We discussed my health and an issue I have been having with getting my meds. She asked me to call or use My Chart to notify her of any issues moving forward. She put in my RX for 2 meds and asked to return in 3 months.

Dr Chang was patient, kind, a great listener and answered all my questions without rush. It truly felt like what a doctor visit and relationship should be.

I believe that Dr. Chang is genuinely concerned about her patience. She reinforced my belief that I should not be taking a medicine that might not be needed.
