Dr. Paul Rehder is my dermatologist
I have gone to a number of dermatologists in my long life, and am pleased to say Dr. Rehder is the best of them. He is accurate, fast, considerate, and even provides discounts for cash clients. Dr. Rehder has done two minor operations for me and I am extremely pleased with the results.
I don't know what the previous reviewer experienced, but noting his/her very poor English, perhaps there was a failure to communicate.
