Our Story
Our story

Dave joined Thrivent in 2011, after feeling called to serve people through a financial services organization driven by a higher purpose. Over the next several years, he built a team to serve northeastern Kansas and beyond. The Flint Hills Group now boasts six team members and continues to grow.  

Blaine joined forces with Dave, his friend and mentor, after graduating from Kansas State University in 2015. He strives to make an eternal impact by helping clients work toward their dreams and be good stewards of the resources entrusted to them by God.  

Dave’s son, Dillon, came on board soon after Blaine, and personifies our commitment to generational financial planning. Dillon relishes the close relationships he’s built here and feels our strong bond enables us to serve clients more effectively.  

In 2019, Scott joined Flint Hills Group. Dave became Scott’s financial advisor—and dear friend—after Scott moved to Manhattan in 2013. Their friendship eventually led to conversations about Scott joining the team, which he felt called to do shortly before the pandemic began.  

Shelby and Amy round out our team by providing much appreciated administrative and insurance support while helping carry out our mission.  

At Flint Hills Group, faith and family are two core values shared by everyone on our team. We take care of each other and push each other to be better. We celebrate our families’ successes and lift each other up during difficult times.  

We look forward to working with you and your family, and we hope to help you—and the generations that follow—make the most of God’s many gifts.

Dave has been with Thrivent since 2011 and takes pride in helping support Christian families not only locally, but in many other states. Dave has two primary objectives when serving clients. The first is to help them make their retirement goals a reality and 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 forming flexible plans in case of unexpected life changes.  

Dave’s diverse background includes military service, corporate leadership, entrepreneurship, marriage, coaching, parenting, and now, grandparenting. All these experiences help him relate in some way to most of his clients.  

Outside of the office, Dave has helped create and grow the region’s largest free Christian music festival, Flint Hills Praisefest. He also cherishes spending time with his family and whatever outdoor adventures he can find.

Dillon’s competitive nature has also been an asset throughout his life. He is a former collegiate baseball player, a high school coach, a marathon runner, and most recently, a long- distance dirt/gravel bicycle rider. In addition, his competitive nature is evident in the financial plans he writes for clients, where he strives to find solutions that will help them “win” as it relates to their personal financial goals. 

Dillon and his wife, Shannon, have been married since 2015. They have four children: Eleanor, Ada, Jack and Madelyn. When not spending time with his family, Dillon enjoys running, lifting weights, hunting and fishing.
