Dr was very informative Took plenty of time with me.
The service was great. I had an appointment and arrived on time and was seen without waiting. The staff was very efficient and Dr.Patel explained every detail about the procedures I am going to have.
The nurses and doctors were very thorough and made me at ease.
This was my first visit with Dr. Wayne Liu, since Dr. Thomas Ardnt retired. I was sort of apprehensive, but he made me feel so at ease just like Dr. Ardnt. I am so glad that we found another great doctor to handle and treat my ulcerative colitis. He was calming, he was informative and he was just what I needed at that time. Thank you Dr. Liu for taking over Dr. Ardnt’s practice and being there for me.♥️
My experience at the Oak Lawn location was very pleasant. Dr. Wayne Lue and staff were very kind, thoughtful and explained the procedure step by step. I will definitely go back for my 3 year follow up.

I was seen in Oak Lawn and was treated so nice and friendly. Felt really comfortable. And they're also professional at the same time.
I had a positive experience at GI Alliance in Oak Lawn. The entire staff from the reception area to check-in and preparation for my procedure was friendly, courteous and very respectful. Dr. Bluemenstein was attentive and courteous and clearly explained everything to me.
Dr. Lue and the GI Alliance office staff are all very courteous and efficient. I really appreciate the great experience they provide on each and every visit!
Excellent care over the decades. I wouldn’t go anywhere else.
Dr Blumenstein provided excellent service. He listened very closely to my symptoms and came up with a treatment plan.
Dr. Lue and the whole team were great. From start to finish I was well informed and all my questions were answered in a kind and professional way. Everyone I was in contact with introduced themselves, explained what their role was and what would be happening every step of the way. Extremely kind, professional staff, I felt very comfortable and at ease with the whole team.
Dr. Lou and his team are the best. Thank you.
Dr. Wue and staff were amazing! Every person I encountered was warm and friendly. They all seemed to genuinely love what they were doing and care about the patients. That really helped to quell my anxiety about my procedure.
Dr. Lu is absolutely amazing! Very positive and connected. It's not his way or the highway. Open dialogue with patient well at least with me. I would highly recommend him to family and friends.
