Office Source was started 17 years ago by Fenton residents Kraig and Kerstan Simmons. They supply local businesses with a full line of office supplies, copiers, fax machines, printers and other office equipment. The team at Office Source offers consultative services to help provide clients with their exact needs for their business. Starting with a small customer base, many in the St. Louis area, Office Source now has more than 900 customers throughout the United States.
