Our LA office is pleased to offer mechanical engineering services led by senior mechanical engineer, Joseph “Joey” Balducci, PE. Joey is working closely with Coffman’s established San Diego mechanical engineering department to support clients in LA and OC and throughout Southern California.

Our San Diego office’s mechanical engineering team is led by principal, Louis Abbott, PE. Together, Joey, Louis, and the mechanical team strengthen Coffman’s capabilities and expand our support for clients from LA through San Diego. Our mechanical engineering capabilities are diverse and you’ll see our hand in projects such as the California Highway Patrol Facility in San Bernardino, Southern California Edison (SCE) Central Administration Building Improvements, and the University of California, San Diego (UCSD) Southwest Fisheries Science Center at Scripps Institution of Oceanography.

We look forward to chatting with you about your next mechanical or multidiscipline project.
