This 2020/2021 school year marks my seventh year of teaching and my fifth year here at Duker! Prior to teaching in District 15, I taught first and second grade at a Charter School. I attended Roosevelt University, where I graduated with my Bachelor’s Degree in Elementary Education with a concentration in Psychology.
In my free time, I enjoy playing with my Chihuahua Tucker, shopping, reading, and baking.
I truly love being a teacher and I am so grateful to be here at Duker with your children each and every day!

This is my 21st year teaching 5th grade in District 15. I taught my first year at Landmark, then moved to Duker when it opened as a 4/5 building. I've been here ever since! I have a Bachelor's degree in Elementary Education from Illinois State University (Go Redbirds!), and a Master's degree in Educational Leadership from Aurora University. For as long as I can remember, I've always loved working with kids.

This year begins my twentieth year at Duker teaching fifth grade. I am truly blessed to be able to teach in the same district that my children, Jessica and Victor, attended. I was born and raised in Australia and was a teacher there in the early 1980s. I met my husband while he was stationed in the small town, Woomera, I was teaching in. I have been living in the US since 1987 and became a US citizen in 2012. In my free time I love to read, sew, crochet, scrapbook, and spend time with my family. I look forward to every day and the adventure each new class gives.

Czesz, if you're not Polish, that means hi! I am Sabina Rodenkirch, and I love being surrounded by kids each day as my job. I grew up attending this school as a 5th-8th grader when it was formerly called McHenry Junior High. Now, I am lucky enough to continue to make wonderful new memories as a 4th/5th-grade looping teacher. I received my Bachelor's Degree from Northern Illinois University and then went on to earn my Master's Degree in Teaching from Webster University. I am blessed with love from my husband, Brian, and our son Caleb. On the weekends you can find me on the soccer field cheering on my son, or daydreaming of being on the beach somewhere!

Mrs. Sullivan
My name is Amy Sullivan. This is my 23rd year teaching special education and my third year as a teacher here at Duker. I am honored to be a part of the Duker community!
I was born and raised in Minnesota where I raised my two children with my husband. We moved to Illinois in 2021 and have enjoyed getting to know the area. We do a great deal of traveling to Minnesota and Wisconsin to see family and friends. We love watching football—I am a HUGE Minnesota Vikings fan—we love being outdoors, and I love reading and baking.
