This was my first visit and I was nervous. I didn't know what to expect. I was worried for nothing. The waiting area is quite nice. New looking, quiet, and not crowded. They took me back for the exam, right at my appointment time which is great because I hate waiting in doctor's offices. The tests were administered and my audiologist explained everything clearly each step of the way. I really am impressed with Optimum Audiology.

Response from the owner:Hello, thanks for the great review!

Response from the owner:Hi, we're delighted to hear about your experience. Thanks for sharing!

Office staff is courteous and the Dr. is very friendly. He explained the testing process and was very accommodating. This was more than I had anticipated. I was measured for Hearing aids, and custom molds were made of my outer ear and were ordered. Over all I give this office a 10/10 for being so well organized and service was excellent.
