He had me twice EGD procedures in the last two years. The 2nd one obviously indicated a deterioration It showed acid reflux. It could partially explained what caused my discomfort, weight loss and stomach pains. Unfortunately, this man didn’t provide any useful treatment or suggestions on diet. Even worse, he said the pain I described may not be real, and suggested me see a psychologist. I asked “would you please give me a referral ” he replied “you should consult your family doctor “ Very very unprofessional, irresponsible and heartless.

The WORST Doctor ever. I have been seeing this doctor for the past 3 years, he made me wait for 3 hours for each visiting. I finally had enough and asked him why he does this to his patients. He gave no apology nor a reason. He has no respect of his patients time. All he cares is to collect money from patients.

This is worst experience. Dr is two hours late with no apology. Receptionist offers no help.

Worse doctor ever had, don’t go there

1. We had an colonoscopy appointment at 1pm. He ended up seeing us at 5pm. The nurses in Memorial Hermann Southwest Surgery Center said he always arrives the facility late late. So we waited over 4 hours for the colonoscopy( the patient was really hungry).2. Not patient to explain the surgery and listen to our questions.3. You will receive surprising anesthesia bill afterwards. (Be sure to ask whether he chooses the in network anesthesia company before the procedure) Even if we go to a in network hospital and choose a in network doctor, we received two out of network separate bills regarding to the anesthesia. And the bills are over $5000.

Always late and treats patients without insurance terribly

Terrible. Got a test around the end of last year and never received the results. I called numerous times to get them and had no replies. He encouraged me to get this expensive procedure, was an hour late for it, then never bothered to let me know what my results were. Now I am trying to just personally get my results and they have me juggling calls between the old and new office just to get my results. Yangs bedside manner is sub par, he uses scare tactics. He also was always at least 45 minutes late for a scheduled appointment time. The women who answer the phones have no respect for you and act like your an idiot. Just dont go here.
