Capt. Zac Zumwalt serves as the Corps Officer for The Salvation Army in Waterloo, Iowa, alongside his wife, Capt. Karissa Zumwalt. Originally from Kansas City, Zac has worked with The Salvation Army throughout the Midwest since 2014 in Chicago, Kansas City, Watertown SD, and Sioux City, IA.
With more than a decade of ministry and community service experience, Zac is passionate about putting faith into action through practical support and outreach. In Waterloo, he and Karissa oversee multiple community programs, including three homeless shelters, an extensive feeding and drive-thru pantry program, and a local church congregation, all aimed at meeting both the physical and spiritual needs of the community.
Zac and Karissa are celebrating 12 years of marriage this year and have two children, Theodore (2 years old) and Lincoln (5 months old). As free time allows, Zac enjoys spending time with his family, a really good book, and going to the theatre to see the latest movie release.
