Our History

We are mechanical engineers based in Santa Rosa, California. Together, we share decades of experience designing educational, industrial, institutional and commercial facilities.

Our clients include many of the premier architectural firms in northern California. We also work directly for leading high-tech manufacturers, health care facilities, colleges and public school districts, and wineries. We are proud to receive most of our business from long-standing, repeat clients.

Although our projects extend throughout California and west across the Pacific to Southeast Asia, we focus on the Greater Bay Area and northern California.
