SHAZAM Network, a member-owned electronic funds transfer network and processor based in Johnston, has named Paul Waltz as its new CEO. Waltz replaces longtime CEO Michael Hollinger, who retired from the company in August. SHAZAM hired Waltz as executive vice president and chief operating officer in 2013; he was named president in 2014. Prior to joining SHAZAM, Waltz spent more than 30 years working with community financial institutions in Iowa, most recently as chief operating officer with First American Bank in Clive. Waltz has also held a variety of positions on the SHAZAM board of directors, including chairman. “Under Paul’s leadership, the team is as focused as ever on addressing industry challenges and assuring SHAZAM’s continued success as an industry leader,” said Tim Kintner, chairman of SHAZAM’s board of directors.
