Mary Kay was born July 5, 1959, in Clinton, Iowa, to Ralph and Ellenor (Mangan) Kroymann. She grew up in Welton, Iowa, where her family owned the feed store. Mary Kay graduated from Central Community Schools in DeWitt and went on to receive her Nursing Degree from Moline Public Hospital School of Nursing. She married Terry Rossmiller on June 23, 1989,  at St. Anthony’s Catholic Church in Davenport. The couple resided in LeClaire, where they raised their two children. They retired to Calamus in 2024 to be near her family. Mary Kay worked as nurse for over 40 years, primarily in the ER at St. Luke’s in Davenport (now MercyOne Genesis-East).
