Waited 47 minutes to see the doctor! The first time ever. I didn’t mention it to him, but I just figured he spent time with patients.

Dr. Wiesen is fine to deal with. With a good listening ear. The office leaves a bit to be desired: a slamming front door, lots of folks waiting for an hour to be seen and a carpet that desperately needs to be replaced.
