In February, PBS airs a special series called Makers. It's about women in the United States who make a difference in their profession. This week, Dakota Midday is featuring women in South Dakota who have made a difference. Karl Gehrke visited with Sister JoAnn Sturzl and Sister Lois Ann Sargent on Monday in the first of this week-long series. The Presentation Sisters have a long history in South Dakota with ministries dedicated to education and healing.
