What Our Patients Are Saying...

  • Kay Derm has been my go-to for a few years now. I have been seen for problematic skin, have had the veins on my legs treated post pregnancy, IPL to treat the brown sun spots on my face and laser hair removal treatments. On occasion, they might be running behind schedule, but in my experience, that is only due to the very thorough evaluation/treatment I've had. Alia, thank you for yet another great visit.

    They do amazing laser work, especially physician assistant/ laser technician Nancy Primo who is super skilled and knowledgeable. Dr. Kay is very caring and kind. He cares very much and it shows. I have had fabulous results with his Sclerotherapy procedure. He oversaw a treatment of Actinic Keratosis - held steadfast that it was not cancer to hold off biopsy, despite other doctors saying to cut.
