Meet Our Teachers and Staff

Pacific Crest is accredited through the AdvancedED

All of Pacific Crest’s Primary and Elementary teachers are trained through Association Montessori Internationale (AMI) training centers. Our Middle School teachers attend Montessori trainings for the adolescent level; these are offered by the North American Montessori Teachers Association (NAMTA) in partnership with AMI.


HEAD OF SCHOOL: Dorrie Knapp Guy

Dorrie Growing up in a small college town in Oregon’s Willamette Valley, her years in Montessori education are rooted in her own early childhood experiences in a Montessori Primary school.  With a BA from Smith College in Northampton, MA and experience working at Pacific Crest beginning in 2005, she went on to earn an AMI Elementary diploma from the Washington Montessori Institute in DC and a Masters of Education, with a focus on adolescent education, from Loyola University in 2009.  She returned to Pacific Crest School in 2009 to teach in the Middle School and in Lower and Upper Elementary classrooms.  

In late 2015 she stepped into administration as the school's Operations Manager, and she became Head of School in 2016.  She completed program certificates in NAMTA's Whole-School Montessori Management and the NWAIS New Heads Institute in 2016. 

Dorrie lives in Ballard with her husband and two nieces.  She finds inspiration through her work with the dedicated and creative teachers, staff, parents and children of Pacific Crest as each discovers with joy their own unique gifts and character.

“Directing our action toward mankind means, first and foremost, doing so with regard to the child. The child, that ‘forgotten citizen’, must be appreciated in accordance with his true value. His rights as a human being who shapes all of mankind must become sacred, and the secret laws of his normal psychic development must light the way for civilization.” (Education and Peace)

Assistant Head of School

Jennifer took the dive into the Montessori world when her then three-year-old daughter joined a “children’s house” classroom back in 2000, and has worked in Montessori school administration since 2004. She received AMI Primary training (ages 2 ½ - 6) from Montessori Northwest in Portland,  a B.A. in history from the University of Washington, and an M.Ed. from Loyola University Maryland.

In her spare time, she can be found learning a new tune on the ukulele, singing in a local community choir, reading a good book, quilting, or exploring the beautiful Pacific Northwest.

“An education capable of saving humanity is no small undertaking: it involves the spiritual development of man, the enhancement of his value as an individual, and the preparation of young people to understand the times in which they live.” —Maria Montessori, Education and Peace

"If the idea of the Universe be presented to the child in the right way, it will do more for him than just arouse his interest, for it will create in him admiration and wonder, a feeling loftier than any interest and more satisfying." - To Educate the Human Potential

Erin has been teaching at PCS since 2006. She holds a Master's in Teaching from the University of Washington as well as a Masters in Conservation from the University College London.

I love working at a school where the staff are so deeply committed to improving their practice, rooted in a deep understanding of Montessori philosophy and a belief in the potential of all people.  A Montessori quote that I keep in mind relates to education as a means to creating a better world.

"An education capable of saving humanity is no small undertaking; it involves the spiritual development of man, the enhancement of his value as an individual, and the preparation of young people to understand the times in which they live." -- Maria Montesssori

Peter is originally from Maine and is currently in his 7th year at PCS and his 6th year as a Middle School teacher at PCS.

"In this fierce battle of civil life a man must have a strong character and quick wits as well as courage; he must be strengthened in his principles by moral training and he must also have practical ability in order to face the difficulties of life. Adaptability--this is the most essential quality." (Dr. Montessori, From Childhood to Adolescence p. 61)

Chuck joined the Pacific Crest Middle School staff in 2006. He holds a B.A. from the University of Washington in Political Science and completed the AMI-NAMTA Orientation to Adolescent Studies in Ohio.

Pacific Crest offers the opportunity for adolescents to develop skills and perspective not available in a traditional setting, highlighted by working on the school's farm on Vashon Island.

"Work on the land is an introduction both to nature and to civilization and gives a limitless field for scientific and historic studies...there is an opportunity to learn both academically and through actual experience what are the elements of social life." -- From Childhood to Adolescence

Amy joined Pacific Crest in 2003. She earned her BA in History from The University of the South in Sewanee, Tennessee, and a Masters of Environmental Studies from The Evergreen State College in Washington.

Sean is married and has twin boys that keep him busy all the time.

"What I enjoy most about working at this school is the variety of work that we get to explore with students.  From academics to cooking to building a stage, I truly enjoy working side-by-side with our students on many different projects".

"Education should therefore include the two forms of work, manual and intellectual, for the same person, and thus make it understood by practical experience that these two kinds complete each other and are equally essential to a civilized existence." -- Maria Montessori
