Everyone in the office was very friendly and Dr. Maddala was very caring, asked a lot of great questions to get more information about what’s going on with me and was quick to schedule further testing. Great visit, not rushed.

This 4 star review is based on the reason that I asked for an appointment with one doctor, but another was assigned later . It’s not that I’m not happy with the doctor assigned for me but it was the timing of the new doctor changed before my appointment day. Anyway the service from doctor Blessy John was good.
