Mainsail Management Team

Jim Keliher

Jim has been investing in the future of Boston for 36 years. He began purchasing and resurrecting Back Bay apartments in 1980 – the same season Oil Can Boyd was drafted by the Sox – and has remained committed to the city ever since.

Jim guides the team in acquiring, developing, and managing high-end residential properties in the Back Bay, Beacon Hill, Brighton, and the South End. He is deeply involved in every Mainsail project and plays a key leadership role in initiating investment and development opportunities. To date, he has renovated hundreds of apartments throughout Massachusetts. Jim is very involved with South End Baseball and is happy to support the Mainsail Management Red Sox!

Tom Helms
Head of Construction

Tom has 24 years of experience managing high-end residential and light commercial construction. From 1989 – 2010, Tom worked as a project superintendent and manager with Connaughton Construction. Tom coordinated and oversaw construction crews through project completion and worked closely with the city/town officials to obtain necessary permits.

A stickler for quality, Tom keeps Mainsail’s projects on time and within budget. He knows every crewmember by name and regularly conducts progress meetings with property owners, architects and subcontractors to ensure client satisfaction. His “drama-less” approach and experience in managing multiple projects have been invaluable assets for our team.
