What I want my patients to know about me:My Care Philosophy: A diagnosis of skin cancer can be scary, but fortunately, the treatment doesn't have to be. I look forward to providing you and your family with the best care possible right here in your community.What I do when I'm not seeing patients:I like to spend my free time with family, friends and my dog. I enjoy staying active and spending time on the water, using proper sun protection of course!

This is the third time Dr. Zaleski has performed Mohs surgery for me. She's very kind, treats me with respect & is concerned for my comfort. Since she knows we live 2.5 hours from York, she offered dissolvable sutures, so I wouldn't have to make the drive to have them removed.

I had a very positive experience with the surgeon. She explained everything as she was going with the surgery and was very caring.
