Poor service. Could not even say hello. Just closed the door when she saw me sitting. I was the only person on waitlist. I left and went to a different location.

Great experience! I didn’t have an appointment, so I arrived when they opened at 7am as a walk-in. I only had to wait 15 minutes before being seen!

I was nervous going into my appointment based on the reviews, but I was brought back exactly at my appointment time and the staff was incredibly friendly! The nurse was one of the nicest people I’ve met and was great at calming the nerves.
