I saw Dr Chang for 3 years for anemia. He was very thorough and reassured me that everything was as ok and we were covering all of our bases in terms of finding a cause. Highly recommended him!

Doctor Chang expresses himself in a very professional manner with an outstanding bedside manner. He articulates himself extremely well so there’s no questioning his diagnoses.

I arrived at 10:00 a.m. for a 10:30 appointment that was supposed to be a 2 and 1/2 hour consult. I was told this by the person who had scheduled the appointment. With that being said, I did not get pulled in until 11:00 in the morning. Then as Dr. Chang decided to try to figure out why I was there after I was referred to a doctor who basically works right beside him proceeded to gaslight me. The appointment lasted 15 minutes. I made sure to call my insurance company and let them know not to charge for the 2 and 1/2 hour consult that I was supposed to have when the appointment only lasted 15 minutes. I was very disappointed and that is not what a doctor is supposed to do. When you ask a patient a question you allow all the patient to answer. You don't raise your hand and put it in front of the patient's face and say let me finish so we can get to a diagnosis wrong. You need to turn your license in. You should not even be a doctor
