River Forest is a prestigious large suburb immediately west of Chicago, adjacent to Oak Park, where median household income tops $144,000, home values average nearly $669,000, and 76% of adults hold college degrees — one of the most affluent and architecturally distinguished communities on the Chicago area's western corridors. The modest enrollment creates a tight-knit community where students and teachers know each other well. Families in the area reflect a community invested in their children's futures, and the school draws from a neighborhood where education is a clear priority.

The suburban setting gives families access to community amenities while maintaining the neighborhood character that makes this a popular choice for local families.

With an enrollment of 69 students, Keystone Montessori School is a smaller school where families often find a close-knit community atmosphere. Smaller settings can mean more individual attention from teachers and staff, though they may offer fewer extracurricular options than larger schools.

As a private school, Keystone Montessori School operates independently from the local public school district. Families considering this school should inquire about tuition costs, financial aid availability, and the admissions process. Private schools are not required to follow the same curriculum standards as public schools, which can be either an advantage or a consideration depending on your priorities.
