Gary Sheridan, Project Superintendent

Gary has worked for Colantonio since 1989 and is deeply experienced with renovation and new construction work, particularly in the public sector.  His projects include historical restorations, affordable housing, higher education, academic, municipal buildings and maintenance facilities. Gary consistently impresses owners (and fellow staff) with his ability to assess problem situations and offer viable solutions on the spot.  He recently oversaw the gut renovation of the Eliot Upper School in the North End and is now building the new Hopkinton Early Elementary School.  

New Superintendents and interns are routinely assigned to shadow Gary so that they learn from the best. "I can't imagine doing anything else," he says.  "No two days are alike, and working for Fran is like working for family.  I consider myself pretty lucky."  Fran's only beef with Gary?  "I have to force him to take a vacation!", he says.
