Dr. Kohan provided relatively quick and very professional services for me. After my first appointment it only took the following week for him to perform an ear surgery. During the surgery he repaired my punctured ear drum, dealt with a cyst, and manipulated a partially damaged bone in order to enhance my earing. Three months later I have normal hearing in my left ear and am taking dive classes starting next week. I highly recommend Dr. Kohan due to his professionalism, and courteousness.
