Mari Scherma Sennott

A full time real estate professional since 1999, Mari Scherma Sennott leads Mari Sennott Plus/Today Real Estate. She is joined by her husband, Hank, and the newest “plus,” Colleen McDermott.
Mari and Hank have been partners for more than 35 years. They are proud parents and grandparents who have lived on Cape Cod since 1994.
A native of Attleboro, MA., where her family owned the popular Jerimar’s Restaurant for 25 years, Mari brings considerable know-how to every transaction, whether first-time home buyers or empty nesters.
She is consistently one of the most effective realtors not only in Today Real Estate, but Cape-wide. Throughout their career, Mari and Hank have sold over 400 homes.
Mari is a member of the Board of Directors of the Cape and Islands Board of Realtors (CCIAOR).
When they recently found themselves to be empty-nesters, Mari and Hank downsized and sold the home where they had lived for 28 years to purchase a smaller property. In the process, they gained a new appreciation for what buyers and sellers experience; a unique perspective that they bring to every transaction.
Mari says the goal of Mari Sennott Plus/Today Real Estate is to ensure that when you “make your move with Mari” it is as enjoyable and stress free as possible.

Hank Sennott
Hank joined Mari in 2016 to form one of Cape Cod’s most successful real estate teams: “Mari Sennott Plus/Today Real Estate.”
He brings more than 40 years of marketing experience in the real estate, utility and non-profit fields to the team. He also taught communications on the college level for 25 years, most recently at Bridgewater State University. Twice a week he co-hosts a YouTube and internet morning program, “What’s New Cape Cod?” with legendary Cape Cod broadcaster and current Executive Director of the Mashpee Chamber of Commerce Stephanie “in the Morning” Viva.
Along with Mari he is a member of the Events and Engagement Committee of the Cape and Islands Association of Realtors. Hank previously served on the Finance Committee. He is an active member of the Boards of Directors of Mashpee TV and Lemonaide-co, the non-profit that operates the Mashpee, Bourne, and Barnstable Farmers Markets. He is a former Sandwich (MA) Selectman and Finance Committee chair and recently completed a term as a member of the Community Impact Council of the Cape and Islands United Way.
In October 2025, he achieved a long time goal with the publication of his first collection of short stories: “Chances: Stories and Memories Real and Imagined.”

Colleen McDermott
In January 2026, Mari and Hank were excited to welcome to the team a new “Plus,” Colleen McDermott.
With a background in home improvement from working on the television show This Old House, Colleen has a passion for the real estate industry and gained an eye for potential in every home.
A South Shore native who now lives on Cape Cod, Colleen brings deep local knowledge of both areas. Her past experience in production and publishing has honed her skills in organization, communication, and coordination – essential qualities in navigating real estate transactions.
She spends her spare her time exploring local beaches with her dog, Raffie, checking out different golf courses with her husband, and finding the best spots to post up with a latte and good book – all recommendations she is excited to share.
Colleen says that she brings “patience, enthusiasm, and a keen attention to detail to help buyers find the perfect home or for sellers to put their house in the best position for a successful sale.”
