Board of Directors

Wendell Vinson
Pastor Wendell and Lynda Vinson.


Wendell and his wife Lynda Vinson became pastors of Canyon Hills Church, Bakersfield, California, over thirty years ago when it was a small congregation in need of revitalization. Today Canyon Hills is one of the leading multisite churches in Southern California, pioneering fresh approaches to church planting, church renewal, and taking the gospel to unreached tribes.

The Vinson’s unwavering compassion to love people to Jesus inspired innovative ways to serve their community better, such as Fort Faith, an award-winning children’s ministry center; Champion’s Club, a state-of-the-art center designed specifically for children with special needs; Florence Gardens Senior Living Center, an affordable housing development for seniors; and Frazier Woods Conference Center. Canyon Hills is a forerunner in the CityServe network with the ongoing renovation of a nearly 200,000 sq. ft. commercial shopping mall that serves as an inner-city outreach center and CityServe warehouse HUB.

Wendell has trained pastors, advised world leaders, and helped coordinate government briefings in Washington, DC, as part of the White House Office of Faith-Based and Community Initiatives.

He currently serves or has served as a member of the board of trustees for Vanguard University, Costa Mesa, CA; Covenant Foundation of California; Convoy of Hope, Springfield, MO; Covenant Community Services Kern County; Kern Leadership Alliance; Mission One Eleven; and National Faith Advisory Board.

Wendell and Lynda have two adult children and are proud grandparents of their four grandchildren.
