5 /5 George Santana: I’ve been with Dr. Cohn for over a decade - over the years I have moved from Dutchess, to Rockland and most recently to White Plains and no matter how far, I continue to see Dr. Cohn. She and her staff are courteous and personable. Dr Cohn and the hygienists here have a gentle touch. Painless and pleasant. They’re the best!
