School Principal Work Phone: 847-296-3490

I am a graduate of Catholic schools, receiving a Bachelor of Arts, from DePaul University, and a Master of Education, from Loyola University. I have been committed to Catholic school students and parents for thirty-six years as a principal, teacher, and assistant principal. I believe Catholic schools complement the role of the family in nurturing a strong sense of self-worth in the child, enabling each child to meet the challenge of today and tomorrow, and demonstrate responsible stewardship in the community and society.

I have been principal at St. Emily School for eleven years, working with the teachers to develop a complete Curriculum Guide, in conjunction with Archdiocesan frameworks and Common Core State Standards, and raising standardized test scores to National Blue Ribbon standards.

I came to administration after being a classroom teacher for twenty-five years. My comprehensive teaching experience included grade levels third through eighth. While teaching in Florida, I worked, concurrently, with college-bound high school students in Upward Bound, a federally-funded program for disadvantaged students. In addition to full time teaching responsibilities, I was assistant principal for seven years, and curriculum coordinator.

I consider myself fortunate to be part of the excellence that is St. Emily School.

Parish Secretary Work Phone: 847-824-5049

Sue and her family have been members of St. Emily since 1990. In the early years, Sue, Bill and her boys, Patrick and Andrew, were well known in the school and parish, being involved not only at school activities (boys are St. Emily alumni), running fundraisers, Scouts (both boys are Eagle Scouts) and volunteering when needed. Sue is very proud of her family. Her boys are Notre Dame College Prep alumni. Patrick graduated from Valparaiso University, IN with a degree in Meteorology, Andrew graduated from Miami University, OH with a degree in Zoology & Environmental Sciences.

Sue began working part time at the school in the Extended Care program and worked her way up to school secretary. When the job for parish secretary became available, Sue decided it was time for a change, a job which offered new challenges and a flexible schedule.

Sue has taken on the role of Protecting God’s Children site administrator, bulletin editor plus many others. She enjoys helping parishioners with all their needs. If she doesn’t know, she will try to find someone who does. Sue looks forward to assisting you with any of your parish needs.
