    12-Acre Trails and Forest Restoration Project Update

    Coming this November - The Southern Loop Trail!

    Trail building has begun in the southern section of our forest restoration, between the barn and Jones Road. This loop trail will be accessible year round by all ages of students at Cedar River Montessori, providing additional outdoor lesson space and allowing students to observe the forest restoration up close! In February, we will plant hundreds of native trees and shrubs to begin growing our new forest.

    "This is our first year at Cedar River Montessori and we love it... even in the midst of a pandemic! We can tell our 3-year old is thriving by the way he talks about his classroom and teachers and by the huge smile on his face when pick him up in the afternoon. His teachers are supportive, creative, and keep open lines of communication."

    I really feel like I stand out at [high] school academically and have a deeper understanding of the world than my classmates, and I am very grateful for that.

  • Whitney, '98

    I am an ICU nurse and I always want to know how and why things work the way they do, which is a huge part of my role in the ICU. I feel CRMS gave me the tools and the drive to ask questions and never stop learning.
