It is my honor to be a part of the St. Mary community and serve as the Principal of St. Mary School.  My name is Ryan Schwieterman and I am a product of schools within the Diocese of Columbus.  I attended St. Michael School during the 5th-8th grade and then attended Bishop Watterson High School.  While at Bishop Watterson, I was a 3-year Varsity tennis player and played golf for one season.


I attended the University of Dayton, a Catholic Marianist University.  I majored in Middle Childhood Education with a focus on grades 4-9 Science and Social Studies. While at the University of Dayton, I was involved with the crew (rowing) team, was a Resident Assistant for three years, and participated in a Spring Break service trip my junior year to the Dominican Republic working with locals to build an eco-tourism facility in the Cloud Mountains. That summer, I studied abroad in Dublin, Ireland at Trinity College taking education and history courses while being fortunate enough to travel around Ireland, Northern Ireland, and Scotland for the British Open.  I returned to St. Michael's where I taught 7th and 8th grade Science and 8th grade Reading.  I also coached the JV girls and boys tennis teams at Bishop Watterson for several years.  While teaching, I received my Master's in Educational Leadership, again from the University of Dayton, and began pursuing my goal of becoming a school Principal.


Outside of education and school, I enjoy traveling, the outdoors, and officiating high school athletics.  While I've been fortunate to have been in Ireland, Scotland, the Dominican Republic twice, and China and am excited about what travel the future may hold.  One of my favorite hobbies is officiating and in the fall I am an OHSAA and NCAC Football official and an OHSAA Field Hockey official.  During the winter I officiate boys and girls high school basketball.


I look forward to getting to know the students and their families as the year progresses.
