Dr. KOSS is, without a doubt, the best in her field. I travel a distance to see her. She is in Commack now with a beautiful office and a great staff. She is caring, professional and can spot any type of growth as tiny as they are, immediately. Thank you, Dr Koss. I am so thankful I found you.

Dr. Koss is truly exceptional. She consistently respects appointment times, which speaks volumes about her professionalism and consideration for her patients’ schedules. Her bedside manner is second to none—warm, attentive, and genuinely compassionate. She takes the time to listen deeply to every concern, making sure you feel heard and never rushed. Her care feels personal and thorough, and it's clear she’s deeply committed to her patients' well-being.

The staff in the doctor are so nice and professional. I got all of my questions answered and I was seen on time. It is a beautiful Office and everyone is extremely knowledgeable.

Great staff, clean, very positive experience.

Office staff super friendly and efficient. Dr and assistant were thorough. No waiting for the appt. Highly recommend

So incredibly happy that Dr. Koss opened her own practice. I saw her years ago elsewhere, but could no longer take the impersonal, filled with "red tape", behemoth that Schweiger Dermatology became. Dr. Koss is knowledgeable, thorough, and has a wonderful disposition. Making appointments with her office staff is easy and professional. I was seen on time for my appointment; there was no waiting.
