I was there around may 1, and was charged 185 $ for "new patient fee" when I have been going there for about 15 years. Was in and out in 20 min. I called to talk to someone about my charges and asked for the doctor to call me back so I can see why I was charged so much. It has been 2 weeks and still no call from anyone.
