Patient verified via Press Ganey

I really enjoyed meeting and working with Dr. Maher. He didn't make me feel rushed, took the time to explain everything carefully to me, and answered all of my questions. So many doctors now appear rushed and just ready to get to the next patient. It was refreshing to work with a doctor that took his time and showed genuine interest in the patient and helping the patient.
