Los Angeles, CA– Keystone Business Advisors is pleased to announce the successful acquisition of Design Build Associates (DBA) by Ownershift, an investment platform backed by committed capital from venture firm Downing Capital Group. The transaction marks another successful deal facilitated by Keystone’s tailored M&A process, which is designed to uncover both strong financial value and cultural fit.
Founded in 1983 and headquartered in Southern California, DBA has long been a respected leader in construction management and consulting services, specializing in projects for Homeowners’ Associations (HOAs). With over 475 clients served and more than 350 years of combined construction experience among its team, DBA has earned a stellar reputation for its expertise in coordinating contractors, architects, engineers, and other professionals to deliver high-quality results across a broad range of residential and multi-family projects.
Dennis Brooks, owner of DBA, will remain involved in a consulting role to support a smooth transition. One of DBA’s seasoned executives has been promoted to the role of President and will now lead the company under the new ownership.
“After four decades of building this company, finding the right buyer was about more than just price, it was about finding a partner who valued our legacy and our people,” said Dennis Brooks. “Keystone’s process brought us multiple qualified buyers and allowed me to make a thoughtful decision. I’m excited about the future with Ownershift and confident in the leadership team moving forward.”
Keystone’s go-to-market strategy in this transaction included listing the business without an asking price, inviting the market to determine value. This strategy attracted a strong pool of qualified buyers and led to multiple competitive offers, giving Dennis the opportunity to choose the partner that aligned best with his goals for both the business and his team.
