Dedicated. Generous. Witty. Tireless, Enthusiastic. Kind. Those are words that first came to mind when friends and colleagues were asked to describe John Ryan, who led the Venice Area Chamber of Commerce since 1999. Ryan, 59, died from an apparent heart attack Aug. 12 after mowing his lawn. Under Ryan’s leadership, the Venice chamber grew to 1,100 members, supported a thriving downtown and formed a young professionals group, among many accomplishments.
