Jeff Olsen

President and CEO

Jeff’s passion, and pride in his family’s business, propelled BTN from being a first-time home improvement store and supermarket supplier, to International Grower of the Year in 2022.

He moved from grower, to sales, VP of sales, President and then in 2009 when he purchased Brookdale Treeland Nurseries Limited, he became the CEO. Since that day Jeff has created a familial environment for all his workers and propelled this company into a leader of horticulture. He has served on many industry boards and committees throughout his career and is currently the Treasurer of Landscape Ontario and Grower’s Chair of the Canadian Nursery & Landscape Association. Outside of the industry, Jeff is a board member of the Young Presidents Organization as well as a co-founder of Friends for Life, a cancer research charity which he founded with his wife Carol.
