Two Mount Mercy University students are gearing up to spend their summers doing missionary work in Africa. Dia Brown, a junior nursing major from Urbandale, Iowa, will travel to Sierra Leone and work with a team at Jonathan House Ministries, a house for orphans. Elizabeth Brumm, a senior English major from Cedar Falls, Iowa, will travel to the small village of Dafor, Ghana as she joins forces with the Fellowship of Catholic University Students (FOCUS).
