Litchfield Middle School officially has a new leader with the promotion Friday of social studies teacher Ben Storrs to interim dean of students at the school.

Storrs was moved into the position by Superintendent of Schools Christopher Leone after middle school Principal Stephanie Kubisek, who is out on paid medical leave, announced Friday that she will resign on June 30.

Leone and Kubisek announced the plans in separate letters to the school community. Kubisek is recovering from her fifth surgery in two years and has been out of school since December.

“These two years have affected me and this recovery has left me with me with time to reflect on my future,” Kubisek wrote in her letter. “After much consideration and many discussions with my husband, it is with a heavy heart that I have made the difficult decision to leave Litchfield Public Schools to pursue other challenging educational endeavors.”

Kubisek has been in the school system for nearly 20 years. She previously was the assistant principal at thee high school, where she started out as a guidance counselor.

In Storrs, the middle school has a capable leader, according to Leone.

“Ben has done excellent work over the past six weeks and I believe that will continue with the support of (high school principal) Ms. Kristen Della Volpe and myself,” Leone wrote in his letter.

Storrs’ social studies classes are being taught by substitute teacher Sandra Macinaus until a long-term substitute teacher is hired this month to teach the classes through the end of the year, according to Leone.
