Educational Interventionist

Hello, my name is Kelly Hahn. I am the Educational Interventionist at St. Mary's. After graduating from the University of WI-Madison and marrying my husband, Matt, I took time off to raise our children - Elsa, Mike, Lucy and Tony - who attended St. Mary's. I enjoyed teaching kindergarten at St. Mary’s for six years and I currently enjoy helping our students with their academic, behavioral, and social needs. I believe wholeheartedly in the spiritual and academic benefits of a Catholic education. When not at school, you can find me at my children’s athletic events, restoring our old home, supporting the arts, or cheering on the Badgers and Packers.

Hi, my name is Sandi Eckardt.  I grew up on a farm in Athens.  I enjoy helping others and was a CNA and later became a teacher’s aide at St. Mary’s.  I now live in Rib Falls with my husband, Gary and two daughters.  Deveney and Sierra both graduated from St. Mary’s School and now attend Marathon High School.  In my free time I enjoy baking, reading and making quilts.
