Donald Ostrem began this Edmonton-based family business in 1963. Today his grandchildren, Ben Tungland, Erik Tungland and Sarah Tungland, own and operate Ostrem Chemical together. Don was a one-man show for many years and beginnings were humble. He would put on a suit to make sales calls, then come back to the shop, put on his coveralls and go to work. He’d change yet again to deliver the products before donning his suit to head out on another sales call. Eventually Don was in a position to hire, and the fourth person he hired was the man that would marry his daughter the following year, Roar Tungland.
