Josh Tewalt re-joined the Idaho Department of Correction on December 1, 2018, after two years as the director of operations for the Association of State Correctional Administrators (ASCA). In that role, he travelled the country promoting the profession of corrections, supporting ASCA members in the implementation of evidence-based practices, and influenced national policies and practices affecting public safety.

In those roles, he helped secure funding for a pay-progression plan for uniformed corrections staff. He was also responsible for strategic initiatives, including shaping a department reorganization to better position the agency to meet future demands.

As director, Josh oversees the entirety of IDOC's operations including its nine prisons, five community reentry centers and seven probation and parole districts. The department has an annual budget of $313 million (FY22) and employs nearly 2,000 correctional professionals. They are responsible for the incarceration and community supervision of 25,000 people convicted of felonies.

Josh is an Idaho native, a rancher, and a former executive vice president of the Idaho Cattle Association. He served on the staff of two Idaho governors and a U.S. congressman.
