Mazzetti is an employee-owned benefit corporation, committed to creating healthier, enduring environments. Though our story began with a small team of MEP engineers, almost 60 years later, we’ve grown to 200+ people, in locations across the U.S. (and in India) with diverse expertise addressing the spectrum of client needs in the built environment. Mazzetti consultants deliver world-class MEP engineering and technology solutions, rooted in local culture . We aid clients in the planning, designing, optimizing, equipping, illuminating, sustaining, even “reimagining” of environments, as appropriate. The people of Mazzetti believe in seeking and delivering meaningful work. We intentionally work predominately in the Healthcare industry, notorious for its energy-intensive, highly complex, highly regulated buildings, AND highly impactful relationship with communities. This is our calling. Mazzetti thoughtfully connects people, design, and technology to create lasting, positive impact.
