I had an appointment at the office on 4880 Wynn and overall received fine service. The ladies working the front were helpful, but a bit forceful with other customers. I waited in the lobby for 20 minutes and waited 5-10 for the doctor in the patient room. My appointment was at 7:20am, so there was no crowd. Dr. Chen was quiet, but answered any questions I had. I have been to better offices, but this one will do fine for now.
