I love the staff and everyone was open to me and they listened to me and they were really genuine and they welcomed me in. But when I went into my appointment with him, he made me feel uncomfortable and I couldn't speak my mind. I had said something about a previous medical decision that one of my GI's had said before him and he said, sorry well I'm not him, and this is what we are going to do. And I was like, okay, well I agree with you and I like your knowledge but the way you approached it was very rude and like I don't have a say. I'm not disappointed in him, I just don't know about it, it's my first visit. I will go back and see how it goes and see how what he said helps me and judge from that. But he just seems very snappish

I cannot think of one thing to improve my experience. Dr. Yang and the entire staff provided the most excellent care. They calmed my anxiety, were so knowledgeable, reassuring AND very important to me they have a compassionate grasp of the human condition and were very KIND. They are EXACTLY the kind of people one needs to see when they are unwell. Thank you Dr.Yang.

Staff and Provider were very professional and answered my health concerns. No rush.

Dr. Yang was the problem. I will never go back to see him or refer him to anyone. Met me for 10 min before saying "there's nothing I can do to help you". Barley asked me questions about my stomach and issues, mostly asked questions about my cannabis use age. I left sobbing, crying talking to my entire family trying to be calmed. I've have stomach issues since I was young and for him to say "just cut cannabis out of your life and your diet would be better" is ABSURD.

My experience with the office staff was great, Dr. Yang was great. The only issue that I had was my initial referral went all the way back to May. So it took me almost 6 months to get in.

Was all good

From the time I got there to the time I left everybody at the office is the most professional. I mean I've had some health problems in the past and I've never been treated at well. From the girl that greeted me, to the girl that took me back, to the one that took my vitals me, and including the doctor. Everybody was very comfortable and I feel very confident that they're going to figure out what my issues are and and give me a better quality of life. I am going to recommend this office to anybody that I know. Thank you and have a good day.

Excellent doctor, I wish you didn't call every time after I visited doctor. I see multiple doctors and get a call every time it's excessive.

I don't think it could have been better. All my questions were answered. If there was no answer, they said so. Dr Yang and PA B.Nivens are top of the line in my estimation.

not ask me to come in earlier than appt time and then not get in patient room 15 minutes after original appt time

Have more than just one person who can schedule appointments. Having only one person who can perform ANY function is ridiculous.

Place a sign in the hallway that can be seen from down the hall. It is hard for a new patient to see where to go. ??

All significant concerns were respectfully and appropriately responded to by Dr Yang.
