I make sure to provide individualized treatment with a care plan that is tailored to meet my patient's needs. Over time I build relationships with my patients and their families, working together to make sure their plan continues to treat their skin using the most appropriate and state of the art treatment available.

I have been battling skin cancers for forty years and over that time have seen several dermatologists. Dr. Katz is by far the best. He is skilled at finding my skin cancers and knows what treatment is best. Have lost count of the number he has treated. Every single one has had clean edges. Not one has reappeared. He is a remarkably skilled physician!

I recently accompanied my father-in-law to an appointment with Dr. Katz. We were both very happy with his sincere and personable interaction during the entire visit. Dr. Katz asked my father-in-law many questions so that he could thoroughly understand the symptoms he's been experiencing and what might be causing the issue. Dr. Katz then talked with both of us about his treatment plan and made us feel as though we were going to be working this out as a team; that was very comforting to my father-in-law.
