I have great confidence in Dr. Alter. I had a lot of bad dental work in the past, and he fixed what needed to be fixed, at a pace that balanced the dental urgency, the cost, and my tolerance for sitting in the chair for hours. He is friendly, responsive, and caring. He does not participate in any insurance plans, but he will always submit paperwork to your insurer for out-of-network reimbursement. He has one receptionist and no other staff so overhead is low; keeps costs reasonable for a midtown dentist.
