Our Team

Teresa Shippen teaches one of our Transitional Kindergarten/Kindergarten classes. Teresa began her teaching career in Live Oak, California working at a three room school out in the orchards. She taught 3-4th grades for eight years, and loved being a part of the community of Live Oak. Teresa left this job to be a stay-at-home mom for her two young children. During the thirteen years that she stayed home she had a third child. Jacob, her oldest, currently attends Chico State and will be graduating this Spring (2016). Jessica is currently a sophomore at the University of Oregon in Eugene and Peter, her youngest is currently 13. Teresa began her path back into teaching Kindergarten at Chico Montessori, a then private school in town. Her Montessori training was a great fit for the way she felt education should be.

Adam Mankoski teaches one of our Transitional/Kindergarten classes. Adam joined our team for the 2022-2023 school year, more on Adam coming soon!

She entered the Sherwood community in the 2016-2017 school year, substituting in every class and acting as a resource for some of the teachers, while working on her Masters in Education.

Happy Yasko My name is Happy and I hold teaching credentials in both Special Education and Multiple Subjects. Prior
to teaching here at Sherwood Montessori, I was the Ed Specialist for the 6th grade inclusion class at
Palermo Middle School. Before that I taught special ed at Youth for Change in Paradise. It was there that
I found my role in the world of education. A professor of mine said it best when she said, “you didn’t find

Special Ed, it found you”. I have found that all can learn, we just need to find the language that makes that possible. My favorite quote from a student is, “You tricked us into learning Mr, Happy”. I am an adventurer by nature. I have gone on a mission trip to the indigenous people of Costa Rica in the rainforest and have also been on 2 trips to Haiti. I am honored to be called a member of the staff here at Sherwood Montessori School.

Anne Adams

Anne Adams is one of our Lower Elementary teachers (1st/2nd/3rd). Anne is also an accomplished musician and writer. In her own words: When I was a student, my teachers often said, “You should become a teacher!” and I thought to myself (with all due respect), “What do they know? They’ve always been teachers!” and I set out to find out what else I could be.

After college, I moved to Portland, Oregon and became a copy clerk, a soda jerk, a “professional” musician inasmuch as that’s possible, a music analyst for a commercial database, an ad-writer, a copy-editor, a fact-checker, a describer of diamond rings and wedding cakes, a volunteer organizer of an all-ages music festival, a stop-motion animation movie crew member, a ukulele radio jingle composer, and the city’s only midnight fry-cart dinosaur fortuneteller. My last stop was a six-year sojourn as an arts and theater critic, ‘til finally I decided, “I’ve explored enough. It’s time, after all, to teach.”

I chose to train in Montessori pedagogy because, when practiced as intended, it’s limitless. Maria Montessori calls elementary education “Cosmic Education” because 6-12-year-olds’ appetite for new information and ideas is so vast. Draw a kid’s attention to anything specific, and they’ll impulsively zoom out to see the “big picture” that surrounds it. They earnestly want to know it all, because they’re building a worldview. I can appreciate that, and I can help! I share the few things I know, and I show them how to find out more.

I also appreciate the values promoted by this hundred-year-old teaching tradition—particularly cooperation, courtesy, philosophy, patience, and gratitude. I strive daily toward meeting these ideals myself, and I’m committed to showing students these vital ways of being.

Prior to joining the Sherwood team, I taught grades K-6 in a rural public school in an unincorporated region east of Redding. I’m exhilarated by this new opportunity to work within a larger group of more experienced colleagues and a more diverse group of students.

Hey...maybe that’s why they always told me I should be a teacher.

Anyway, here I am.
