The McMahon Group is a Boston-based commercial builder that still believes in the marriage of style and functionality. Since 1992, James McMahon and his group of highly-skilled builders and sub-contractors have been building and renovating commercial properties that are not only functional, but are accurate reflections of both the companies that occupy the buildings and the communities in which they reside.
