Progress has always been our business. From the industrial age to the digital frontier, Yoh has stood at the intersection of innovation and execution for more than eighty years.

1940s–1950s

Born in the industrial age, built for innovation. Yoh began as Duncan Tool Design, delivering technical talent to innovations that defined a generation. Within a decade, we became trusted by pioneers like Lockheed, DuPont, and IBM to power the next era of engineering.

1960s-1970s

As the world looked to the stars, Yoh engineers were already helping to get there. Our teams contributed to NASA’s early Mercury and Gemini programs and even helped shape the 1964 World’s Fair Monorail. When Yoh joined forces with Day & Zimmermann, our ability to deliver across industries grew exponentially.

1980s-1990s

Innovation met scale. Yoh introduced one of the first managed staffing programs for GE, earned ISO 9002 quality registration, and expanded nationally through key acquisitions. Our IT, engineering, and scientific divisions set new standards for specialized recruiting.

2000s

Yoh went digital. We launched an early VMS platform and surpassed $98 million in online sales. Our technology-first approach earned us the ASUG Impact Award and positioned Yoh as a leader in workforce innovation.

2010s

Momentum multiplied. With new leadership and a growing portfolio, including the acquisitions of Starpoint Solutions, Embedded Resource Group (ERG), and GECO Deutschland, Yoh became one of the largest recruiting firms in the U.S., surpassing $500 million in revenue.

Today and looking ahead

Eighty years later, Yoh remains one of America’s longest-standing tech consulting, staffing, and enterprise companies—and one of its most forward-thinking. We’re still here, still innovating, and still delivering the expertise that keeps work moving.
