I and my whole family have been going to Dr Bernstein and now live in Florida. When I need a procedure I fly back to Long Island bc he’s the best . Most caring, most professional and I’ve gone to two different Drs here in Florida and there’s no comparison. My wife now needs a procedure and we’re calling this morning to make an appointment as she’s not comfortable with any other. Thank you Doctor
