The Rev. Antonio Dittmer, at Newman Center since 2005, has been reassigned to Immaculate Heart of Mary Seminary, Wenona, Minn. A farewell celebration is planned for 5 p.m. Sunday at the center, 501 S. Main St. In August, Sister Silvia Tarafa will become center director. Local priests will rotate coverage of Mass, said Dittmer. The center serves students at four Twin City campuses and Eureka College. Three full-time ministers and two part-time development directors also lost their jobs. Phone calls on Thursday and Friday to the diocese were not returned. Dittmer hopes to return for the chapel’s dedication Mass, expected sometime next spring.
