Sheriff ThomWelcome

Welcome to the Pennington County Sheriff’s Office. I’m Sheriff Kevin Thom and became Sheriff on January 3, 2011. The Pennington County Sheriff’s Office has 370 employees and an annual budget of about $26 million. The Sheriff’s Office serves over 100,000 citizens spread out over Pennington County’s 2,784 square miles. We also serve a high number of visitors and tourists to our area as Pennington County is home to Mount Rushmore National Monument and Ellsworth Air Force Base. Last year Mount Rushmore received over 3 million visitors. The county seat, Rapid City, is a regional hub for transportation, medical, retail and a host of other services.
