Experience and Dedication

Old School Montessori's greatest strength is our people: a diverse team of experienced and dedicated educators, assistants, and administrators—some with us since our founding over 22 years ago. Our Montessori Directresses focus on each child as an individual, helping each become an independent learner and thinker. Each classroom is led by a Montessori Directress and at least one Assistant. Our Directresses and Assistants facilitate a culture of curiosity and make their classrooms places of discovery.


Pre-Primary (Toddler) Directress

Kelly Ong

Kelly's background is in Early Childhood Education and she is completing Infant/Toddler training at Seton Montessori Institute, a Directress preparation institute that has graduated thousands of qualified educators for over 40 years. 

Kelly's passion for education is sparked by watching kids work hard every day to achieve their goals—she finds it amazing to witness and very fulfilling. The aspects of Montessori education that she most values are letting the child take control of their learning, and allowing them to do things they didn't know they could do, by respecting them and giving them choices.

Line time is a very special time in Kelly's classroom. During this time, each child is welcomed to the class and they participate in singing songs they love, dancing, and playing musical instruments. The children look forward to it every day.

Born in Highland Park and raised in Round Lake Beach, Kelly currently lives in Waukegan.

sevdije muslimovic

Born in Bosnia and Herzegovina, Sevdije received a bachelor's degree in business and put it to use working for a large corporation for 11 years.  When civil war broke out in her homeland, Sevdije and her family emigrated to Germany.  Five years later, her family moved again to the United States and her journey in Montessori education began.  

Sevdije decided to follow her passion for teaching at the Midwest Montessori Teacher Training Center.  She received her certificate in primary education in 2004 and has been a part of the faculty at several Montessori schools before joining the staff of Old School Montessori.  Sevdije has been a part of Montessori education for 18 years and still loves working with children every day.

When she is not busy at school, Sevdije enjoys traveling the world and spending time with family.  She has traveled all over the United States, from Florida to California.  She loved spending time with family in Hawaii and Canada, and going back to Bosnia and Germany to visit family and friends still living there.  

Mrs. M, as she is affectionately known to her students, spends time with her busy family whenever possible.  She and her husband, Sefket, a mechanical engineer, try to visit their two children as often as possible.  Their daughter lives in California with her husband and is an assistant principal.  Their son, a business major, works inside sales and lives in the area.  

Sevdije shares that she loves working in Montessori education for the opportunity to watch the children develop and learn over the three year cycle.  She has always loved helping others, so she creates a classroom environment where children grow and bloom as they follow their own path to knowledge.

Elementary Directress

Colleen Hodges 

In her 19th year of teaching at Old School Montessori, Colleen grew up in Chicago in a family of teachers. She always knew that teaching would be a part of her life and she could not be happier with her choice!

Colleen began her career at the Special Education District of Lake County and spent four years in Libertyville schools before coming to Old School Montessori with the opening of the upper elementary class in 1999.

While her undergraduate major was horticulture and she was an accomplished floral designer, she chose to follow a different path into the world of education. She attended Midwest Montessori Teacher's Training Center for her course work in Montessori education.

Mrs. Hodges is the mother of three grown children with families of their own. Keeping up with her nine beautiful grandchildren keeps her young! She enjoys traveling with her husband, gardening, and sports, especially the Bears, Blackhawks, and White Sox. You can find her curled up with a good mystery whenever she gets the chance to read.

Mrs. Hodges works to create a community of acceptance and friendship in her classroom. She encourages each child to celebrate what makes them unique. Being the spark that ignites the interest of a child is the very best reward for an educator and something she strives for every day.
