Recently, we brought you the story of Nadel Architects ownership transition, as part of our continuing series on building and growing your business. We were intrigued by the process and wanted to get more details on the nuts and bolts of ownership transitions in general. We went right to the source: attorney Bill Mandel, who handled the ownership transition plan for Nadel Architects, and his partner Laura Terry Howard. At their San Francisco–based firm MBV Law, Mandel specializes in transition planning for architecture, engineering and design firms, including mergers and acquisitions and ownership transition programs, while Howard's practice area runs from addressing formation issues in the start-up phase to developing and implementing an exit strategy. Here, they give us more insight into a critical process in the life of a firm—when done right, it can mean thriving for decades to come.
