Founded in 1966 by Jack Lockton, Lockton Companies has become a premier insurance agency. After Jack died in 2004, the company’s tradition was maintained by his brother, David, who serves as chairman. Jack’s son, Ron, is vice chairman, and two other sons, Don and Steve, are successful producers. Lockton’s family atmosphere extends to its more than 5,600 associates around the world; the company has been recognized repeatedly as a great place to work in national and local award programs. And the philosophy works from a business perspective, too: Between 2007 and 2015, Lockton grew organically from $629 million to $1.24 billion; it now serves more than 48,000 clients.
