How likely are you to recommend Dr. Mertz?

(Select your rating)
I see Dr. Mertz at the downtown office and would recommend him to all my family and friends. He achieved what other doctor's could not and that was find what was causing my head congestion and allergies. I have one negative complaint and that is the billing department. I had a billing question and tried calling at 3:15 pm. I was told the biller leaves at 3:00 pm, so if I had a question I should call before that which is unheard of and very inconvenient.
