Mason was born on the island where his father, Tom, was a longtime partner and broker with Congdon & Coleman Real Estate. Mason joined the team in 2012, working alongside his father and his cousin Matt.
Mason's favorite part of growing up on the island was being able to explore. Nowadays, he has a major passion for collecting and fixing up old Land Rovers and Range Rovers, and continues his explorative roots by roaming the shore of the island on his ATV during the winter months. His favorite place on island is either the middle Moors or Coatue, and when he makes it off The Rock, Mason loves the British Virgin Islands.
