OakHaven Montessori School is a growing private school that highly values people who are self-driven, professional, and want to make a difference. We look for individuals who are devoted to an authentic Montessori education. Fantastic teachers are our best resource. 


Our teachers have the benefit of well equipped classrooms, tuition discounts for their children, continuing education, and competitive salaries and benefits including health, dental, vision, and life insurance as well as an employer matched retirement plan. Our school is conveniently located in O’Fallon, MO, yet tucked away on four beautiful acres with gardens, wildlife, and a natural playground. 


O'Fallon is a small town about 35 miles from St. Louis, the gateway to the west. The Katy trail, many conservation areas, state parks, and the scenic wineries of Defiance are all within a short drive. Being close to a big city while also far enough away allows for ample opportunities to explore the area for cultural, recreational, and environmental reasons. 


OakHaven Montessori School is an equal opportunity employer, and diversity and inclusion is a strong shared value among our administration and staff.  We do not discriminate against employees based on race, color, religion, sex, national origin, age, or disability. 


Benefits of working at OMS: 

  • The potential to be sponsored in your AMI diploma course. 

  • Our beautiful, natural environment is nestled on four acres in the St. Louis suburb of O'Fallon, including a soccer field, gaga pit, gardens, and playground. 

  • Classrooms are sunlit, warm, inviting, organized, and fully equipped with authentic materials developed by Dr. Maria Montessori. 

  • You get to be a part of making a difference in young children’s lives, ultimately creating a more peaceful future. 

  • Opportunities to develop relationships with colleagues of the same mindset and values.
