Established in 2004 by Stephen Callahan, Global is the result of the restructuring of an organization with heritage to1954.  The firm was created to focus on the real estate development segment of the industry.  Global’s founder Stephen Callahan was a principal with John T. Callahan and Sons prior to this reorganization. The firm’s second generation growth included property development not only in New England but in Florida and the Southeast. Together with his4 brothers, the firms functions were formalized and reorganized, with John Callahan forming JTC III and moving into Florida offices, Pat, Tim and Mike reorganizing under the moniker Callahan Inc. and Steve dedicating his collective time to Global here in the New England Region.
