I would like to welcome you to the 2019-2020 school year! The year to Rethink, Reimagine and Rebuild! My name is Will Seidelmann, and I will be the new principal for the Chicago Heights Middle School- Home of the Spartans- opening the summer of 2020!


I couldn’t be more excited to start this year in District 170, but first, how I got here. I attended Eastern Illinois and earned dual certificates in Elementary Education with a Math Concentration and Special Education (K-12.) I began teaching with Southwest Cook County Cooperative for Special Education in their Communication Development (C.D.) Program housed at Andrew High School. I then left the cooperative to coach and move to more of a math focus. At Plainfield Central High School, I taught students with emotional and behavior disorders and mathematics (Algebra 1 and 2.) I coached varsity girls’ volleyball and freshmen girls’ softball. I completed my masters in Educational Leadership at Concordia University and my Special Education Directors Endorsement at Lewis University. I then moved into administration as the Assistant Principal in North Palos at Conrady Junior High School. After two years, I left to become the Principal at Hickory Creek Middle School in Frankfort. 


I spent four amazing years in Frankfort where we earned athletic and academic awards. We won several athletic state championships, awards in Mathletes, Speech and Scholastic Bowl, and our Band, Orchestra and Chorus programs were extremely successful too.  Hickory Creek was also named a 2018 Blue Ribbon School of Excellence and was recognized as a Model Middle School through the Horizons Schools to Watch Program and Association of Illinois Middle Grade Schools (AIMS.)


This year, I am privileged to dedicate a majority of my time to planning and preparing for the successful opening of the new Chicago Heights Middle School. In addition, I will be working with the 5th through 8th grade mathematics team alongside Ms. Bishop. I began working in the beginning of July in “The Heights” and each day is a new project and adventure. My hope is that through this planning, while you all are focused on an amazing 2019-2020 school year, that I can live in two worlds; the 2019-2020 mathematics world and the 2020-2021 Inaugural Middle School Opening year!


My experiences as a teacher, coach and administrator have taught me that teachers, students and family members have the most up to date information on their school and community’s climate and culture. In order for me to learn more about Chicago Heights, I ask that anyone interested in meeting with me, and sharing with me some ideas you may have about the middle school, to please make an appointment. I will have a traveling office throughout this year so that I can spend time in 5th through 8th grade classrooms. My plan is to get to know as many of the students, parents, staff and community members prior to the middle school opening as possible.


I look forward to getting to know each of you! Have an amazing 2019-2020 school year.
