At the helm since 2003 is Donna M. Mueller. By law, the CEO is appointed by the governor and confirmed by the Iowa Senate for a four-year term. Donna was most recently reconfirmed on April 11, 2016. Iowa law requires the CEO to have high credentials and experience in pension and investment administration. She received her Juris Doctor in law from Washington and Lee University and is also a graduate of the John F. Kennedy School of Government's Program for Senior Executives at Harvard University. Her commitment to long-term financial health for IPERS is evident in her work with legislators and members. As CEO, she oversees actuarial services, general counsel, internal auditing, and public information, as well as the organization as a whole.
