About HSD Engineering
Repair, rebuild, calibration and systems
Who we are
A second-generation family business: Bay Area since 1993, Concord since 2019.
Dick Hagen designed and serviced vacuum equipment, and in 1993 he founded HSD Engineering in Oakland. The business started with a furnace and grew into the repair, calibration, lab and systems work we do now. His grandson, J. Tyler Hagen, took it over in 2014 and runs it as President.
