At 72, John Quinn doesn’t see retiring from the firm he founded or moving into an emeritus role in his near future. In an interview this week, he challenged anyone questioning his fitness to run with him at the Rose Bowl Stadium in Pasadena, California.

“I’ll leave it to other people how fit and astute I am to run a $2 billion organization,” Quinn said, noting that at any time, his partners can decide who is best suited to run the firm.
