About Colantonio

Since our founding by Chairman and CEO Fran Colantonio in 1978, we’ve carefully grown into a $75 million firm and become a proven leader in managing complex construction and renovation projects spanning the private and public sectors. Throughout, the cornerstone of our firm and our approach to doing business has been to build effective relationships by putting people first.

Through open communication and creative problem solving, our team is persistent, proactive, and resourceful in helping clients, designers, and subcontractors accomplish project goals. We earn our seat at the table by offering a team of highly experienced and deeply engaged industry professionals who share a long history of working together and a track record of exceeding client expectations.

What Our Partners and Staff Say

“One of our requirements of all bidders was to talk to us about how they would approach construction given that it was an occupied building… Of all the bidders, they gave that the most thought. They were really thinking about…who lived here, problem solving from the get-go and finding the best way to stage the construction so that people would be least impacted. That was a huge signal to us that they were the right partner.”
