This was my first visit, the staff were very helpful and nice. I really liked Dr Wallis, he was quite thorough in his exam, not afraid to touch you, good old school training. Explained everything well and answered all my questions. The wait in the lobby was a little long, but understandable and worth it.

My husband is a new patient to Dr. Wallis. He has had 2 office visits & a procedure done by him. We have nothing but good to say about him & his staff. All the staff are very accomodating & Dr. Wallis listens, listens, answers our questions. Very nice practice. Wish we didn't need a Gastro Doctor, but glad we have one that we are happy with.

By far the WORST doctors and staff members I've ever in my life had to deal with. The office manager Susan is on a huge power trip. You aren't allowed to even speak your opinion about your own health issues. They have staff members cancel your appts constantly, they yell at you when you take breather for 2 seconds with your mask on, you wait over 2 and half hours for doctors appointments, you get accused of being aneriox when you aren't, ive been hung up on, I've been made to apologize to everyone in the office or threatened... read more
