Cell: (917) 287-2451

Welcome to central Fairfield County, the best place to live, work, and play. With a mix of happening small cities, and fetching, culturally rich towns, people who live here and move here enjoy a life they relish.

Mark can help you buy and sell real estate here, as well as rent and invest.

Born and raised in Connecticut, Mark returned to the backyards of Fairfield County in 2011. Since then, he has enjoyed three successive homes in the area. He has been grateful for the pace of life, the professional pursuits, and the community and natural beauty everywhere.

Always in fields requiring excellent communication skills, personal connection, and adept analytical abilities, Mark employs these attributes working for you as a professional Realtor. Diligence and service have built a substantial business for Mark and allowed him to help clients with an unlimited range of goals. His business has grown through his commitment to those clients, and particularly to their repeat business and referrals.

His market knowledge covers the broad swath of central Fairfield County from Danbury to Westport and Norwalk to Fairfield. Mark has completed dozens of transactions in more than eight towns and municipalities. In helping clients achieve their goals, Mark thinks creatively and out-of-the-box. Twice he has been the recipient of the Strategy Award for agents who demonstrate an exemplary use of tools, platforms, and approaches.

Mark is active in the industry beyond his work as an agent. As a Director on the boards of the Mid-Fairfield County Association of Realtors and the state-level Connecticut Realtors Association, Mark helps advance professional standards and promotes property owner, seller, and renter interests. Mark is also a real estate investor, owning several rental properties that he has purchased and renovated.

Mark likes to run, race, and work out; enjoys the water and beach; supports the land trust, his place of worship, and his kids’ schools; and loves spending time with his husband and twin sons.
