  • As it is for most people, I realize health is of primary importance. I've been a patient with Newburyport Medical Associates for about 40 years, first with Dr. Mendelson and now with Jane Cleveland. If I have a question, or need an unexpected appointment, I can count on them. This is very reassuring.
