Review for Dr. Cossman

I was very impressed with Dr. Cossman's attention to detail and his willingness to spend the time to explain what had to be done in the treatment of my skin issue. His professionalism is to be commended.

Review for Dr. Cossman

I have numerous skin conditions and growths. Dr. Cossman is extremely thorough, pleasant, and instructive. He diagnosed melanoma in my friend and has found several skin cancers on me. I’m very grateful for his meticulous and wonderful care.
