CSM Corporation develops, owns, and manages a wide range of properties including hotels, commercial real estate, and apartment communities. They're committed to delivering exceptional business results for their clients, while making a positive difference for our employees — and the communities where we live and work. CSM Corporation began modestly when Gary Holmes — CSM’s president and CEO — started selling light bulbs door-to-door in Minneapolis at the tender age of 12. A young entrepreneur, Gary enlisted his Boy Scout troop as a sales force. By age 14, he had earned enough from his light bulb sales to buy his first real estate asset: a set of Minneapolis duplexes.
