I have been seeing Dr. Mathias for about six years now and I am very pleased with the office staff, hygenists, and the Dr. They are prompt, swift to change appointments when things arise, and very helpful in reminding you of appointments. The office is in a great location and is very clean. The office has expert knowledge regarding insurance questions. I would say they are on the expensive side comparated to other dentists, however; you get what you pay for.
