Bethany native and Platte City resident Buffy Smith will serve as Chief of Staff. Smith has served in Graves’ office since early in his tenure, most recently as Missouri Chief of Staff. She previously served as District Director and Scheduler.

Based in the Washington, DC office, Knox County native Jon Harder will assume the role of Deputy Chief of Staff - Washington, DC. He has served in Graves office since 2019 in both legislative and press roles. He will also continue as Legislative Director.
