Ms. Heidi Geiger, Head of School

Serving as an educator since 1996, Heidi embraced Montessori education in 2002 after 6 years of traditional teaching in both public and private school sectors. In 2003, she began her AMS Elementary I-II training at MMTTC (Midwest Montessori Teacher Training Center) in Evanston, IL followed by several years serving as an Elementary Directress. Upon the birth of her daughter in 2008, she took the Infant-Toddler training through Seton Montessori Institute in Clarendon Hills, IL and began her new journey serving toddlers at Seton for the next six years. Though she loved her role as a directress, she began getting more involved in administrative and speaking event roles. Over the next two years, she worked closely with Montessori schools, parent groups, clinics and the like to provide an array of parent education opportunities, promoting nutrition and Montessori practices in the community and homes.

Heidi is a native to Michigan where she grew up with organic goodness and wide open spaces on 15 acres of land. She continues to make frequent visits to see her extended family and childhood friends. She has lived in the Chicago suburbs for 15 years, making Illinois her new home and the birth home to her two children, whom both attend JMS. After serving 21 years as an educator in 7 different schools, Heidi decided to join JMS as Head of School in 2017.


Ms. Kristina Reid, Primary Level Guide

A guide at the Primary Level, Kristina has had many years of experience as a classroom assistant here at JMS, having come to the school in August of 2005. She and her husband moved to Joliet at this time, and then to Shorewood in 2006. She had been in the social work field but upon the move didn’t find work in that field, so applied at the school.

Ms. Reid has recently completed her training at Seton Montessori Institute in Clarendon Hills, IL, with the bulk of the training completed in the summer of 2014. She attended seminars throughout the school year and obtained her certificate after completing her student teaching in 2015. She appreciates the wealth of Montessori experience here at JMS, and the support and guidance from her colleagues.

Kristina grew up on a farm in Odell, IL and enjoys running, working out, Bears football and her family.
