Mrs. Sarah Shivadecker

Testing Coordinator

Sarah Shivadecker has been an educator for 13 years. In 2006, she received her bachelor’s degree from Wright State University in Early Childhood Education. Before teaching at Immaculate Conception, she was called to serve her community as a family advocate, infant/preschool teacher and home visitor with EvenStart through Kettering Schools Grant Programs. Through this experience, she worked with refugees from many places, including Iraq, Syria, Mexico, Turkey and Sudan, helping the families to become assimilated to the US, working with adults as an advocate and teaching English to family members in their homes. She also worked with local families to empower adults to receive their GED, give research based parenting tips, and to keep the young children on track for school with after school tutoring. Some of the families she worked with during this time she has reunited with as students at ICS!

Mrs. Shivadecker has been a 3rd grade teacher at ICS for 8 years now. She is very grateful to be able to teach in Catholic schools after having received an education in Catholic schools at St. Anthony and Chaminade Julienne. She is also very humbled by the ability to serve her community, having been raised and still residing in East Dayton. Immaculate Conception is a special place for her, as her parents and all of their siblings attended ICS and her children Gabrielle (14) and Owen (11) have also attended ICS. She is very passionate about teaching and truly considers it a blessing to live out what she considers her calling.
