5 Important things to know about your business coach.

Member of the Coach's Coach Business Coach Certification Program.


Retail Leadership.

One of the first jobs Don had in his youth was working as a salesperson in a Radio Shack franchise in his Calgary neighborhood. Little did he know, this part-time role would transform into a 20-year career in the retail electronics industry including 10 years managing and later owning a top 10% ranked Radio Shack franchise. After selling his franchise he began a 7-year stint with Sony Store Canada. At Sony Store he worked his way up to Regional Manager overseeing 9 locations in 3 cities. At Sony, Don taught his managers to: interpret their P&Ls, CRM methods, and an interactive 3-day sales course. Don won awards and commendations for merchandising, innovation and sales.


Commercial Product: National VP of Sales.

Don's next major achievement involved companies selling office furniture. As VP of Furniture Sales for Alberta for Corporate Express Canada, Don grew his division to the top region in Canada. He totally revamped the business format in Edmonton and then sold the national president on a nationwide conversion program. Don then became the VP of Furniture Sales for Canada and moved to head the office in Mississauga to complete the conversion work and manage the team. Don grew and aligned his 9 branch locations across Canada from $64M in sales to $89M in just 3 years, a 39% increase.


Manufacturing Sales-Western Canadian VP of Sales.

Moving back to Alberta in 2011, Don took on the role of VP Sales for the Retail and Dealer division of Expocrete, a manufacturer and marketer of concrete hardscape products. Responsible for approximately $35M in sales for Western Canada through large retailers like Home Depot, Lowes, Home Hardware and Rona, as well as an extensive independent dealer distribution network. Don and the Expocrete executive team built up the business over the next few years with a first-year increase in Don's area of 25% and then the business was sold to construction material giant, Oldcastle.


Western Canadian Sales Director.

Moving to a much larger construction product business in 2017, Don became the head of the Direct to Consumer Channel for All Weather Windows in Edmonton. Don was later asked to take on the Director of Sales role for the Dealer Channel for all of Western Canada. Don had progressively moved up at All Weather from $30M in sales responsibility to nearly $100 in two years before Oil and Gas price drops and COVID-19 issues required drastic staff reductions. It was at this point Don started Four Tree Coaching.


Husband, Father, Volunteer and Luge Athlete.

Married since 1982, has two sons, both married, and 3 grandsons. Don spent 10 years with his wife in volunteer leadership roles with a boy's youth organization. He helped develop the winter sport of Luge in Canada in preparation for the 1988 Calgary Winter Olympic Games. He was a member of the National Natural Luge team for 3 years, racing in Europe and Canada, Canadian Men’s Champion in 1986, coached young luge athletes and held various leadership roles in the Canadian Luge Association including National President. Other activities included ten years in martial arts and then another decade learning and teaching Taoist Tai-Chi. Don completed a Masters in Business Administration degree, in 2007.

Don is a consummate professional offering a valuable combination of education and experience well suited to his senior management role. Don is able to plan and execute business strategy on a national scale while adjusting for regional differences. His success in this respect has been his ability to leverage internal and external (supplier) relationships that simply put - make the plan work. Importantly, Don is known as a strong contributor to both his colleagues and the community.

I've had the honor to be mentored by Don. Don is a leader first and foremost, the finest of fine who leads by example. He is respected by all, a great listener, truthful and honest. What I appreciated most about Don is his visionary outlook and impact on business and creative solutions. His brilliant mind is an exemplary asset to any organization. He is polished and professional. What a privilege to work with this man and to witness his impact on others.


Colin Wiebe

VP Sales and Marketing, All Weather Windows

Overall, Don is an exceptional and experienced leader that brings a calm approach, an executive presence and a logical direction to all groups he engages with. I was able to see this with his clients, subordinates, peers and leaders in his time in multiple roles at AWW. He conducts himself with the highest degree of professionalism in any situation and is seen as a genuine leader that strives for sustainable results. I would highly recommend Don for any role in Sales Leadership, Senior Management or Executive Leadership
