Wendell Vinson

Co-founder and Chairman

In 1983, Wendell and Lynda Vinson became the pastors of a small congregation in need of revitalization in Bakersfield, California. They told the Lord that they would spend their whole lives serving Him in this city if He would allow it. More than three decades have passed and Canyon Hills has become one of the leading multi-site churches in Southern California with campuses throughout Central California from the Sierras to the Pacific Coast. The passion of their hearts has never wavered; their greatest desire is to bring a living Jesus to a dying world.

Wendell is known for initiating conversations and collaboration among pastors, business leaders and influencers to bring about community transformation. He gives generously of his time to invest in young leaders for the fulfillment of the Great Commission. He has developed a culture at Canyon Hills that values moving beyond the walls of the church to take the Gospel of Jesus Christ from the neighborhood to the nations.

Wendell and Lynda have two adult children, Jenifer and her husband Kris and Jeremy and his wife Sarah. They are also the proud grandparents of two grandchildren, Oliver and Kaylyn.
