He’s as fine as a hot fudge sundae! Very interactive, terrific sense if humor, very intelligent, able to explain everything in a VERY concrete understandable fashion, compassionate, puts the patient at ease, humane, professional in manner and dress and ethics. I say. Run don’t walk to see Dr. Marc Posner! He was my 2nd opinion- as it turned out, my first choice paled in comparison and I will be using him for my radiation. I was anxious when I walked in and confident I was in good hands when I left.

Dr. Marc Posner is a ray of sunshine in the cloudy days of cancer treatment. He is positive, supportive, and non-judgemental. He takes time to explain radiation oncology and answers every question. He is patient first in his language, his practices, and his support - an advocate for patients in negotiating the journey of cancer treatment. He also has surrounded himself with outstanding staff who also reflect his positive patient care values.
