Mr. Casey

My name is Sean Casey, and I am happy to be the School Psychologist at Duker School! I joined the team here at Duker in 2008. I am consistently heartened by the friendly atmosphere and positive attitude of our school and community. I truly enjoy working with students, families, teachers, and staff here. As a School Psychologist, I assist students who have academic, behavioral, or emotional difficulties. I also work with school teams to find solutions for individual students and groups of students. My role at Duker compliments my educational passion, which is to assist in the implementation of systems of support that positively impact all students. If you have any questions or concerns, please do not hesitate to contact me!

Mrs. Kruse

Hello! My name is Cathy Kruse, and I have been Duker’s school physical therapist since 2018. I feel fortunate that I get to work with students at Duker and Riverwood, but also the middle and high schools. It gives me great pleasure to see how the students grow and progress throughout their time in school. As a school-based PT, my goal is to help students fully participate in all aspects of their school day across a variety of environments. Additionally, I like to focus on the overall health and wellness of students to give them confidence to be as independent during their school day as they can be. I have a bachelor’s of science degree in PT from Marquette University and a doctorate degree in PT from the College of St. Scholastica. I have worked in many settings but enjoy the school and hospital settings the most. My husband and I have 3 children who are working professionally in their fields – two in healthcare and one in engineering. I enjoy walking for exercise, cooking, gardening, and being with my family.

Mrs. Jozwiak

I began my D15 life as a student, where I began Kindergarten at Landmark, and ended at West Campus. Back then, Duker was where I spent my middle school years, but it was called McHenry Junior High. 

After high school, I left McHenry for a bit, but ended up coming back to raise my own family. My husband and I have two grown sons (who also went through D15) and one grandson. That little guy has given me a whole new lens from which to view education.

School, learning, and education have always been important to me and my own life has shown me how incredibly valuable, and even life-changing, education can be. I earned my Bachelor’s degree from NIU, then a Master’s from St. Xavier and a second one from Judson University. 

This is my 25th year with District 15. I spent 19 years in the classroom (most of those at Duker) before becoming an Instructional Coach. I have taught in three of our D15 schools, 1st - 5th grades. I have had some really incredible kids over the years, and it’s so fun to watch them grow into adults and into who they're supposed to be. I haven’t had kids of my own students yet, but I know that day is coming soon!
