Sharon Roberg
Continuing Education Coordinator

Mrs. Sharon started with Kinder Haus in August of 2003. Mrs. Sharon brought a wealth of experience with her to Kinder Haus and we are grateful for her wisdom and her love of Montessori. Mrs. Sharon first became intrigued with Montessori education when her two oldest children attended a Montessori school in Wisconsin. She immediately knew this was something she was interested in and wanted to embrace this for herself. Mrs. Sharon then enrolled in the A.M.I. (American Montessori Institute) training program. She received her AMI Certification in 1981. Mrs. Sharon then taught in Wisconsin at a Montessori school for a few years and in a school outside of Chicago for over twenty years. We are blessed to have her as a part of our Kinder Haus family. Your children will greatly benefit from the knowledge, experience and the love she brings to Kinder Haus Montessori.
