About Seal Harbor Companies
Seal Harbor Companies is a family owned business operating in Massachusetts and Southern Maine. The company is comprised of talented management staff that bring your dreams to reality!
Mark M. Gallagher is the founder and senior manager of the companies. As a developer and builder, he has been developing land and constructing homes in the New England area since 1982. A graduate from Suffolk University, Mark began in this industry first by designing his own home shortly before being married in 1981. After overseeing the construction of our new home, he began developing land and constructing homes in the Acton, Concord and Lexington area. Throughout the next 25 years, he has continued to build homes in these areas as well as Maynard, Carlisle and Westford, Massachusetts.
In the mid-80s, the business expanded to include construction in New Hampshire and Maine. My experience allowed me to expand the business into design/build as well as commercial construction such as office buildings and small resorts.
In the 90s, my construction business evolved to focus solely on commercial construction, including the design and installation of fire suppression systems and construction in larger commercial buildings. Major customers included Irving Oil, AT&T, Exxon Mobil and the United States Government.
Since 2001, my company has enjoyed an office in both Massachusetts and Maine.
Mark P Gallagher is the vice president and manager of Seal Harbor. Mark has been involved in the development and construction business since his graduation from college in 2016. Mark attended Bryant College in Smithfield, Rhode Island and graduated with a degree in accounting and a minor in law. Mark is married and has two wonderful growing children. Mark manages our offices in Massachusetts and also manages the daily scheduling and all of the permitting required to run our business.
