David Spencer
Hometown: Yankton, SD

Spencer believes in working with others in the community to make a difference: from volunteering with local youth sports, serving as an advisory board member for Yankton’s Park and Recreation department, to volunteering with church and area chamber of commerce organizations. As a Thrivent member for nearly 25 years, David has participated in many Thrivent programs. He currently works as director of sales and marketing for Farmer's Pride.
Our leaders work in the best interest of our membership––not third-party shareholders, like publicly traded companies. Clients with a benefit membership can vote in the annual election for the Thrivent Board of Directors. As the organization’s supreme governing body, the board focuses on serving the interests of the membership, both now and into the future. The board establishes and promotes Thrivent’s purpose and oversees major business decisions, and works with leadership to assess and manage risk.
