Clients are saying:

"Mary is the real deal!! She is everything we were hoping for in a realtor and so much more. Mary knows the real estate market better than anyone I know! She is spot on when pricing your home to sell and makes sure every detail is considered to come to that price. Mary is timely when getting home on the market and makes sure it is staged to look its very best so it is appealing to buyers. While working with Mary, you would think that you are her "only client" because she gives you her uttermost attention and is always available to answer any questions or concerns. When a buyer is found, she works very hard to make sure the seller gets the highest price for their house. Mary is not only a dedicated, hard working realtor... she is also one of the nicest, warmest people you will ever meet!! I just love her!"
