Having previously had a very large 13 stitch skin cancer removed I was deeply concerned about a new growth on my face. Deborah Horwitz professionally examined my area of concern and assured me the growth was not cancerous. It was a fast growing skin problem that she immediately solved by freezing it. I was totally happy and delighted with the treatment of my face and with me as a patient.
