I gave them proof of my insurance during my appointment, and they never billed them. Instead the extremely rude and condescending secretary accused me of not having insurance. I offered to fax or email paperwork so that she could bill the insurance and she refused to give me a fax number or email address. I called them several times to help them fill out the paperwork, and they didn't do anything. Instead she sent me a bill for work that is 100% covered by my insurance. They are completely incompetent and rude. Avoid this place!
