Foster began his career in the family business in 2007 when he joined the forest products division of the company, working various jobs in the sort yards. In 2009 he transitioned into the manufacturing division where he eventually moved into the sales and marketing side of the lumber business.

Foster’s passion for the environment drove him to find a more environmentally and sustainable way to provide lumber products. This resulted in the founding of Coulson Cedar, a division of Coulson Manufacturing dedicated to producing the most innovative and environmentally friendly wood siding products on the market today. Today, Coulson Cedar’s engineered products are sold across North America through some of the largest retailers on the planet.

Foster is also conducting the business development and sales & marketing activities for Coulson Aviation. In 2019, Foster transitioned to Co-President of the Coulson Group with his brother Britton Coulson.
