I have had nothing but great care and concern for everyone in the office !!

Dr. Papachristou should be the example for all doctors. He is kind caring and sensitive to my health problems. He is aware of my total medical condition and not just the problem that he is treating me for. He spent considerable time with me and did not rush me out of the office. He answered all of my questions.
