I've been going 5 years. I have friends that have been going 20! His office might not be swank, but his work is excellent. He really knows his dentistry. He's kind and sensitive, and he will work with a patient to come-up with a payment plan if they have no insurance. To give you an example of how good and honest he is, I went to him with a tooth that another dentist wanted to pull. Dr. Wolf realizes that the problems was simply a poorly done root canal. He re-did the root canal and I got to keep the tooth!
