I came to Dr Maddala with painful GERD symptoms and was given the upper GI scope. They found out what was going on inside and worked out a plan to help relieve my pain. She is so nice, any her office staff is great! They make sure youre comfortable and informed, every step of the way. The waiting room is so beautiful!
