San Francisco, CA
The San Francisco office was opened by William P. Mazzetti, Sr. in 1962 as an electrical engineering firm. Since then, the company headquarters has had several names, an expansion of services, and changes in leadership, adding healthcare to its early largely industrial and manufacturing portfolio, as well as mission critical, commissioning, university, and laboratory projects.
Top San Francisco projects include The New Stanford Hospital, Sutter Sacramento Medical Center, the Kaiser Anaheim and San Leandro Replacement Hospitals, and fuel cell installation projects. San Francisco is also home to M+NLB's Climate Change Consulting division, BLUE. Long-term client relationships and repeat commissions characterize both individual and collective efforts.
