About

This location is extremely polarizing. Some patients have a quick, painless experience with friendly staff, while others report long waits, rude service, and billing nightmares. It seems to depend heavily on who is working that day. If you go, make sure you have all your paperwork ready and maybe try to go early in the morning.
