They have a very organized system here. The receptionist was extremely friendly and approachable. She told me the wait would be about an hour and a half to two hours and was extremely appologetic about it. She was right about the wait, but as soon as I was admitted into the exam room the doctor was very quick.
They have an internet service that allows you to check the wait online but it was completely inaccurate. If you're unsure, you can always call the receptionist and ask.
While I did feel completely taken care of by the doctor and nurse, I felt that she was rushing because of the large number of patients waiting to be seen. There were some questions that I had wanted to ask but didn't because there wasn't really the opportunity to do so. I was able to ask the followup nurse.
For someone without insurance the walk in fee was $129, and and x-ray is $50.
