Who Are We?

connecting, coaching, and catalyzing simple churches in Calgary, Canada, and the nations!

The Mosaic Network is a collection of missional communities who are distinct self-governing, self-supporting, and self-multiplying entities which choose to relate to one another relationally. Some of our communities will be part of the Vineyard family of churches while others will have other affiliations. Together we encourage and share gifts and resources.

Don Maxwell

Don Maxwell is an adventure lover, husband, father, stumbling friend, recovering human, creative, big picture thinker and problem solver. He enjoys overcoming challenges by equipping individuals and building teams to accomplish meaningful tasks. “Mistakes are stepping stones” you will hear him say. “Hope” is central to his way of thinking, whether facing obstacles at work or his inner demons.

After graduating from Prairie High School Don completed a Bachelor’s degree in Theology from
Prairie Bible Institute. His family played prominent roles in founding and leading the college. After college he worked with Operation Mobilization in a variety of jobs for about 12 years in Europe and Central Asia. Don’s cross-cultural experiences started in early childhood in Colombia, South America, as a child of missionary parents. Besides enjoying travel and a variety of food he now speaks parts of Hindi/Urdu, Swedish and Spanish.

He met Shestine while working with “OM” and they were married in Sweden, her home country. They now have two adult children, Nina and Kevin, studying nearby in Alberta, Canada and he loves being part of their lives.

Presently Don is owner of a construction company, Maxwell Builders Inc. established in 1997.  For the past decade he has been involved in “recovery” courses, both for personal reasons and for facilitating the healing and growth of others. After personal issues around anger, isolation and anxiety became painful, frustrating and overwhelming, Don began what he describes as “a journey of brokenness and hope.” He says, “It was so refreshing to find a community that was safe enough to be honest about everything; my confusion, pain, doubt, anger, anxiety, and also offer me hope to change on the inside.”

He credits the start of his renewal to the recovery group at Westside Kings church in Calgary. He also participated in the Celebrate Recovery program at Crossroads in Red Deer and facilitated a Freedom Session group at Prairie Bible College in Three Hills. With these experiences of personal growth in community Don keeps encouraging others to form authentic communities everywhere.
