He's the best!! My previous doc gave up after 2 years of negative tests, so I was referred to Dr. Coates. He diagnosed my condition on our first appt, and we found a treatment plan that's more effective than I'd ever hoped for. He continued to follow up regularly to make sure my meds were still helping, was always wonderful at explaining my condition and our options, and genuinely wants to help people. I sadly had to stop seeing him because I changed insurance companies, but he's the best.

Dr. Sharon Coates and her assistant Cora I was scheduled for 11:30 I didn't get called in until noon at which time we spent about a half hour trying to get the equipment to work and it would not they asked me if I would go get some lunch on them and come back within a half hour if the device work I would be seen if not they would reschedule I called they said it worked I got there they had already taken another patient and I was left to sit in the waiting room to wait again all in 2 hours wasted

Dr. Coates seems like a nice guy and a good doctor. But he is severely understaffed all the time. It is near impossible to get a call or email back, which is very scary in some scenarios not being able to reach them. They mixed up my file with another's and tried getting me on different meds until I called and questioned it. I would stay away from here if you're looking for a new gi.

Increased wait time due to hospital based procedure prep time. Dr. Coates is personable and is excellent at his job. I experience much less nausea and vomiting now.

I have been with Dr. Coates for 27 years now. He saved my life and continues to excel in keeping me healthy. He has an awesome attitude and really listens to his patients.

Dr. Coates is absolutely amazing and highly recommended. However, his after hours (especially) and other schedulers along with several other office/behind the desk personnel, are extremely unpleasant and rude! They are easily replaceable and should be asap! Thx for listening
