"After dealing with another agent for years, I decided to switch to Mary on the Square, the best decision I could have made. When the condo went up there were two excellent offers and we closed on the second one immediately. Mary took care of everything from staging, to showings, to the legal part of the sale. She is bright, experienced and warm and I could not be happyer especially in this price range." - Jay Schinfeld MD
