Dr. Kenneth Mark, MD

Referred by a close friend, as a fair skinned woman, Dr. Marks not only makes you feel comfortable on your first visit, but he also really cares about your condition and walks you through the process in a personable way.

Dr Mark and his staff are the best team of medical professionals I have ever seen. One really feels that they are in very capable hands.

This doctor is part of the Stonybrook network, which mandates mask wearing in all associated offices. Dr. Mark's office has a prominent sign attesting to the Stonybrook/Southamption "masks required" policy at his front desk. But, as his unmasked receptionist told me, his office doesn't observe the mask mandate. None of the other patients in the waiting area wore masks, although one was coughing. I am in my 70's and a cancer survivor, as Dr. Mark knows, as I have been his patient for several years. I asked the receptionist to tell Dr. Mark that I would like him to wear a mask, but when I saw him, he was unmasked. I asked him to please wear one, saying, "I don't feel safe if you don't wear a mask." He retorted that he "didn't feel safe having me as a patient" if I wanted him to wear a mask. An average of 500 people are dying every day in America from COVID, 85% of them over the age of 65. This doctor cannot be trusted to place the safety and health of his patients first.

Horrid.... I paid $4000 for ultherapy which was a painful procedure to say the list, which not only didn’t work, but increased wrinkles on the left side of my face.....I still can’t believe what happened... never in all CNN my years had such an awful experience...and no one seemed to care at his office... Would never recommend ultherapy to anyone or the physcian

Dr. Mark gives me the best advices when it comes to my skin. He listens to what my concerns are and finds effective solutions.

Dr. Mark possesses all the qualities a patient wants. He's knowledgable and professional and truly compassionate. We had confidence in him right away. He explained what was going on and answered all our questions. We were impressed that he called that evening.

I was recommended to Dr. Mark by a friend and now I will only see him. He is extremely thorough and caring and very realistic and honest. I feel very confident that I am doing the best for myself by being his patient and would send my family members to him without a doubt.
