Ten years ago, I left the construction industry because I needed a change. I wanted a break from the constant travel, and I wanted to get to know my home town of Denver again. So I took an opportunity to run a foundation and, later, became assistant dean at the University of Denver’s business school. Last year, I was coaxed back to the construction industry to become president of Continuum Advisory Group, a management consulting firm focused on our industry. After a decade away, I decided to catch up on what I had missed by interviewing 40 owners of the industry’s largest firms, many of them past clients.
