Every time I came to this office I have to wait at least an hour, then the doctor just talk to you for a few minutes. One day, my appointment was at 3:45pm. I arrived at 3:35pm. I ve been waiting for almost two hours. I have to leave at 5:30. The doctor never showed up. Terrible management. Never want to come back.
