Mary-Lou provided really exceptional service in all respects. I would recommend her to anyone selling or thinking of selling a house in the Lexington MA area. I wish she could be here in CO to help us buy our next house!

Mary-Lou was extremely helpful in the home buying process. Being a first time homebuyer I had several questions and concerns when looking for a home and Mary-Lou was available practically 24-7 to help. I would never hesitate to recommend her to others, I look forward to working with her again in the future.
