About Us
Mazzetti is an employee-owned Benefit Corporation committed to Bending the Climate Curve™.
As a global MEP engineering design and consulting firm, Mazzetti helps clients solve complex facility and infrastructure challenges—creating healthier, more resilient environments that perform today and adapt for what comes next.
For more than 60 years, we have combined deep technical expertise with a willingness to challenge conventional answers. It’s deeply embedded in our DNA.
We work across the full life cycle of the built environment—from strategy, planning, and design through equipment and technology integration, commissioning, optimization, and renewal. This connected perspective helps clients make more informed decisions about resilience, decarbonization, operational efficiency, deferred maintenance, infrastructure investment, and future growth.
Mazzetti excels when tackling highly complex challenges, tackling uncertainties, and pioneering new paths forward.
Our deepest experience is in healthcare and other similarly mission-critical environments, where systems are complex, operations are 24/7, and the consequences of failure are significant. Our work spans academic medical centers, acute care hospitals, outpatient, behavioral health, and other specialty care, research, aviation, academia, clean rooms, and more. Across all, our focus: aligning people, technology, infrastructure, and long-term performance.
As an employee-owned Benefit Corporation, we’re built for accountability, not just profit.
