5 Stars  I was a few minutes late to a mid afternoon appointment with Dr Fredenberg. Just an annual checkup. I was afraid I’d gotten bumped and would have to wait a long time. Not so. Checked in and was called back in a few minutes. Was completely done in about 20 min. She was friendly and I rushed. –
