Dr. Sideridis is an amazing GI doctor! When you are with him it feels like you are talking to a friend - he really listens to you and always goes above and beyond. The staff however seems to be overwhelmed, limiting their response times.

It was very helpful and I felt the doctor did care even though I had trouble earlier with telephone calls. He advised me to ask for Ashley on future calls to avoid problems. I am feeling much better than before my visit.
