Who We Are
ABOUT HESTER
Hester Fabrication was started in a garage in 2007 based on Daniel Hester’s passion for innovative, precise, and practical design and execution. After years of crafting custom engineered products for a wide range of customers, Hester developed a reputation across the San Francisco Bay Area for providing solutions to unique programs. After working as a civil engineer on the Bay St Louis bridge and the San Francisco Bay Bridge major bridge, Daniel left the heavy construction industry to start a small engineering and fabrication shop in Oakland, California in 2012. The business quickly grew, and the projects become increasingly technical and involved increasingly high-end clients. The business eventually moved to its current location in Hayward, California and continued to grow into a leader in complex engineering and fabrication, serving customers around the globe.
In 2020 Daniel Hester sold his stake of the company to Robert (Bob) Simmons who took over as CEO and John Rettie took over as president.
Bob Simmons, as his role as CEO is responsible for product innovation and strategy. Simmons holds more than 100 patents in manufacturing and construction technology and is a recognized thought leader in combining lean manufacturing, lean design and lean construction for marquee global companies.
Since then, in June of 2026, Kevin Marek now presides as President and is responsible for all business functions. Kevin brings a strong background in applying manufacturing and fabrication technologies in product developments and manufacturing structural steel, as well as experience managing both detailed fabrication processes and large-scale product delivery. He has strong values combined with fresh idea's to grow Hester Fabrication to new heights.
We continue to pursue technically challenging work in a wide range of industries where we can bring
value to our customers.
