Dave Mack

Dave has two primary objectives with the people he serves: The first is to help make their retirement goals a reality. The second is to help them prepare for the “certainty of uncertainty.” Married with two adult children and five grandchildren, Dave understands the importance of flexible planning throughout life changes that we all experience. Dave has been with Thrivent since 2011 and takes a lot of pride in helping build a solid team practice in order to help support Christian families not only locally, but in many other states. A key accomplishment for Dave is helping create and grow the region’s largest free Christian music festival, Flint Hills Praisefest.
