About Me About Me

Margaret Jane ("MJ") is among the top producing agents at William Pitt in the area.  Her proven results are the outcome of her excellent service coupled with her keen ability to make every transaction meet or exceed the client's expectations.  Prior to joining William Pitt, MJ worked on Wall Street for many years in corporate finance, domestic and international investment management and strategic planning for several Fortune 500 companies. She settled in Old Lyme, captured by a shoreline similar to the one she knew growing up in New Jersey. MJ quickly made a world of friends and a name for herself as a person with a can-do attitude who gets things done. She makes it all look easy.

Actively involved in her community, MJ serves on the Board of Directors at the Lyme Art Association where she assists in development activities of individuals and businesses throughout the region. In her down-time, she tinkers on the piano, and "babysits" for all of her friends' dogs!  She is a terrific cook who also holds an MBA in finance.  When asked, she will tell you, "I am grateful to live in a community where I can share both my professional expertise and my personal enjoyment of the arts to benefit others."

If you are considering a sale, purchase, or lease of property in CT, throughout the US or world-wide, call, text or email her for a complimentary consultation.  MJ can bring the world to your doorstep with William Pitt Sotheby's International Realty.

MJ is dedicated and on top of the details! It was a pleasure working with her. Lauralee Cromarty
We could not be more pleased with the way MJ and Roger handled our listing. The time they spent reassuring us during these unprecedented times and the care and concern for our protection during showings made it obvious just how fortunate we were to have chosen two of your best real estate agents. With the many ups and downs of selling our home Roger stayed in close contact with us offering reassurance as MJ kept us apprised of the number of interested perspective buyers. They left “no stone unturned “, even when we had one solid interested buyer, they continued to show the house just encase of a problem with the first one. Roger and MJ made selling our home as stress free as possible. We thank them for their genuine concern for our exposure to the COVID 19virus and their professionalism. Two great agents. George Reynolds, Carol Leach
MJ is fantastic! Very helpful and on her game! Tamera Jackson
