Who We Are

A Family-Operated Mechanical Construction Firm

At Cannistraro, our success is driven by our people. From our roots as a family-owned plumbing shop to our growth to become Boston’s largest mechanical contractor, everything we do is guided by our approach to putting people first.

Our History

In June of 1963, John Cannistraro, Sr. set out to achieve his lifelong goal of entrepreneurship with little more than $1,500 and the support of his wife, Rita. Over 55 years later, the family-owned plumbing shop he founded has developed into a world-class, mechanical construction firm with over 1,000 employees and a sterling reputation for quality and innovation.

Today, Cannistraro offers the most comprehensive package of mechanical services by delivering plumbing, fire protection, HVAC piping and sheet solutions, as well as turnkey service and maintenance to building owners and construction managers throughout New England and across the globe.

Cannistraro leads the field of specialty contracting with our approach to safety, and we’re proud to have been named a “Top Place to Work” by The Boston Globe. Our company is annually named among ENR Magazine’s Top 50 Mechanical Contractors and is currently Boston’s Largest Mechanical Contractor, according to the Boston Business Journal’s “Book of Lists.”
