Outstanding Young Alumnus Award 2026 — Mark Slagle (’11)
October 19, 2026

David Thorton Bell earned a Bachelor of Business Administration from Harding. He spent several years as an audit partner at Deloitte before retiring in 2020. He currently serves as Chief Financial Officer of Castellum, a publicly listed defense technology services and solutions provider. David and his wife Carmen took up the call to be vocational missionaries, keeping their work in proper prioritization as the thing that allows them to live their purpose: serving God. David has been able to find altruistic elements to his financial work over the years, but the real reward in his work comes through the freedom he has had to serve the Lord through their family, church, and broader community.
