At the Grafton clinic, there are many wheelchairs available in the vestibule. They are all very wide and have footpedals that extend very far. They are very difficult to navigate in the small exam rooms and are difficult to navigate in the bathrooms. Can you please get some normal size wheelchairs that have foot pedals That do not extend forward? I was in the West Bend clinic and they had all normal sized wheelchairs. It was a much nicer situation.

Doctor Yoon and staff are always friendly kind listen to you and answer my questions. Makes for a relaxed informative interaction that is appreciated.
