  • Cedar River Parent

    The staff and environment blend so well, I wish I had this when I was younger!

  • Cedar River Parent

    "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."

  • Selena, '18

    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.
