Degenkolb Engineers and Ruby+Associates Combine Firms, Expanding Geographic and Service Offerings

BINGHAM FARMS, MI — San Francisco-based structural engineering firm Degenkolb Engineers (Degenkolb) and Michigan-based structural engineering firm Ruby+Associates (Ruby) recently signed a Purchase Agreement and closed on an acquisition. Ruby’s 55 employees will join Degenkolb, which will now have more than 330 employees in 10 offices.

The Michigan-based team will operate as Ruby+Associates, a Degenkolb Company. With Ruby’s engineering licenses in 42 states, the District of Columbia, and three Canadian provinces, the company’s combined forces will have a much broader geographical reach. The acquisition expands Degenkolb’s presence beyond the western United States for the first time in its 83-plus year history.

“I have known leaders at Ruby for more than a decade, and we have partnered in different aspects of our business for multiple years," said Stacy Bartoletti, CEO of the combined firm. "Our cultures align around giving opportunities to our employees and providing exceptional client service. The combined firm will grow more together than each firm would have on its own.”

Ruby+Associates is a 39-year-old structural engineering firm headquartered in Bingham Farms, Michigan (metro Detroit), with a focus on steel construction and construction engineering services. Tricia Ruby has served as CEO since 2011.

“We are both proud of the firms that we’ve built. Our people are invested in our identities," said Ruby, who is Principal and Group Director at the newly combined firm. "The opportunities that this will provide to our existing employees and new hires are incredible. There will be flexibility in location, in markets to serve, and in clients to work with in the future."
