About Us

Sean Kalman is the founder of The Kalman Co., a luxury real estate brand serving buyers and sellers across Nantucket Island, brokered by eXp Realty. Drawing on a background in hospitality, restaurant management, and design — including Production Director for The Inquirer and Mirror and layout and design at the Boston Herald — Sean brings a concierge-level, detail-driven approach to every transaction, treating each client relationship as a personal one, not just a listing.

A year-round presence on Nantucket, Sean is committed to helping the island’s community — and the people who dream of joining it — thrive.
