    My husband is deaf, and had a horrible time just getting in. This place is very deaf unfriendly. When he triedto make sense of why he wasn't called in, the staff would not look at or answer him, just demanded his ID. They were extremely rude to him and threw papers at him and hold him just sign it! He was trying to ask why a test was not covered since it has always been covered before due to his health condition. They refused to look at him, which blocked communication for him. When he left. Same thing, they would not look at him. This is an ADA lawsuit coming!

    Have chosen this location duplicate times because their service is always great. They are respectful of your time; punctual. They keep the office clean and professional and the team is always kind anytime I see them interacting with me or other patients.

    Sue Reynolds was very professional & cordial. Blood draw was excellent & I had hardly a mark on me the next day.
