Very disgusting service. Rude medical staff on the phone. Need to learn how to speak to people professionally.

Remember not to talk to a single soul in the building or else you are presumed to be buying drugs. Therefore you get kicked out. Mike at the front desk is hella cool. I would give this place 1 star but he’s there so I decided to add the extra 2.
