The 12-Acre Classroom!

Faculty and Staff

teacher and student cirlceOur faculty and staff are proud to be a part of the growth and development of students at Cedar River Montessori. Our administration team oversees finances and executes school operations to support our staff, students, and families. Administration connects our school community with our larger surrounding communities through communications, admissions, and advancement.

In addition to college course work, certified Montessori teachers undergo extensive training to prepare them for the task of guiding the student. For each level (age 3-6, grades 1-3, grades 4-6, etc.) teachers complete intensive training followed by a year-long internship in the classroom. This differs from a traditional teaching program in that the focus is on a smaller age-group, enabling the teacher to acquire a deep understanding of the development, academic, and social needs of their students. Our teachers have all completed Montessori certification for the age group which they teach, and several have additional certifications. We also have a Washington State Certified teacher, several teachers have additional education and training, and a balanced experienced-to-fresh perspective ratio. Our teachers’ classrooms are often visited by teachers-in-training. Several staff have presented locally and nationally at assorted conferences and workshops.

Our assistants bring a wealth of experience and training to their interactions with our students. Working with the teacher in the classroom, they are responsible for helping the classroom run smoothly and ensuring the continuation of the Montessori philosophy from the classroom to the playground and beyond. Our assistants speak several languages, have training in education and other areas, and a wide range of interests that they share with students.

Kelly Humphrey – Program Specialist, Elementary and Middle School Art

Narrowing down one single color for the oft-asked question of what your favorite is, has always been a challenge to Kelly. A soft yellow green reminds her of new leaves as they unfold in the beautiful NW springs that she loves. Tangerine orange is cheerful and tart and makes her think of hot summer days and eating fresh nectarines. Hot magenta pink is 80’s net gloves and Duran Duran music and seventh grade… Kelly believes fully in the richness of color and life in the world around us, in our history, and in what we create. The question of what her favorite part of school is/was has never been a challenge though. She has always loved making, studying, teaching, seeing art. From grade school in central Arkansas, to completing a Bachelors of Fine Arts degree at Brigham Young University in studio arts and a teaching certification for arts education, to her move to Seattle where she’s been creating and selling art, to teaching art in schools, the community, and with her own three children, Kelly always loves the opportunities to develop and share this passion. Kelly joined CRMS as an art teacher and creative leader in 2018. She believes that giving kids an outlet for creative tactile artistic adventures is important for growth and understanding the world around us, and she loves being an art teacher.
