21 Oct Black Lives Matter Statement
The Cottonwood School of Civics and Science stands in solidarity with our Black families. Our goal is to nurture compassionate and confident students who possess the skills needed to confront racism in our community and beyond. We recognize that multiple perspectives and experiences can coexist in one place, and we hold firm in our dedication to racial justice. Hate has no place here. We are committed to fighting systemic racism, especially within our schools and neighborhoods, and we strive to model humility and non-violence for our children.
The Oregon State Board of Education passed a resolution supporting Black Lives Matter on Oct. 15. The Oregon Department of Education announced this move, stating: “the resolution strongly supports justice and dignity for all Black people and renews the Board’s commitment to anti-racism, equity, and access to education as a core value. It also urges Oregon school districts, public charter schools, and education service districts to take several actions to support Black students, educators, and community members including renewing their commitment to anti-racism and strengthening networks of support for students and families who are experiencing increased harassment, violence, bullying, or hatred based on race.”

I grew up in Denver, CO with the Rocky Mountains as my playground, and spent my childhood summers exploring everything that the desert southwest has to offer. I believe that all children should have the opportunity to thrive in the outdoors and think deeply about their environment, which is why I am so drawn to the Cottonwood School and its field based educational philosophy. My childhood experiences in the mountains and my inherent curiosity for the natural world led me to pursue a degree in Geology, and I graduated from Smith College in 2025 with my BA in Spanish and Geosciences. I spent summers in college working for overnight camps with Girl Scouts of Colorado and did a math teaching fellowship my senior year, and knew that I wanted to continue working in education post graduation. I spent the 2025-26 school year as the before and aftercare Site Director at Cottonwood, and am so excited to be joining the team full time this year as an Educational Assistant for the Upper Grade classrooms. Outside of work you can find me reading lots of epic fantasy and sci-fi books, exploring Oregon’s local geology, hiking, playing board games, and obsessing over my house plants (ask me about my Night Blooming Cereus!).
My name is Sam Lloyd. I grew up in California and studied at UC Berkeley for my undergraduate degree, I majored in Economics at Berkeley then earned my Master’s in Education at the University of the Pacific in Stockton. I began my teaching career in Oakland, working with 4th and 5th graders for five school years, and about eight years ago, I moved to Portland with my wife and two daughters. Since then, I’ve been teaching middle school math in local private schools. I joined Cottonwood in 2025.
Growing up in an organic farming intentional community in upstate New York meant spending most of my childhood exploring and learning from the environment around me. After my family moved here to Portland when I was in middle school, my love for learning from the land continued, and while at Cleveland High School I was a regular Outdoor School volunteer. This was a formative experience, and propelled me to pursue teaching science in middle school.
My name is Matthew Gaffney, call me Gaff! I have spent my IT career up to this point doing EdTech and it has been such a rewarding experience. Blending the worlds of technology and education has been a joy to do so far. I strive to make our student’s learning experience the best it can be, and alway try to leave a situation better than I found it. In my free time, I love to go to concerts, explore the wonderful nature of the PNW, and play with my Goldendoodle, Simon. I think every single day is an opportunity to learn something new, and I can’t wait to see what the future holds at Cottonwood. Have the best day 🙂

Hello! I am Daniel McArthur– I joined Cottonwood community in 2024 as Middle School Humanities teacher. I’m a passionate educator with a love for history and writing. I’ve been lucky enough to work with students in a wide range of settings, from an all-girls Catholic school to a homeless youth resource center to public high schools in Detroit, Michigan. In my roles, I’ve seen my students do amazing things when compassionate teaching meets high-expectations. I am originally from Salt Lake City, Utah, where I developed a deep love for mountains and lakes. Outside of the classroom, I enjoy reading, running, and hanging out with my cats. I am always looking for a new book or park recommendation. Let me know if you have any suggestions!

Sara was born and raised in Montana where she grew and nurtured her love and curiosity of learning from and about the natural world with the guidance of her parents and her community. She moved to Oregon in 2007 and attended Pacific University where she earned a BA in Environmental Studies. She left undergrad feeling overwhelmed by the state of the world, and sought out education as a way to foster empathy, critical thinking and creativity in the next generation. Post college, she worked on a ranch in Montana, rode her bicycle across the country and traveled to far away places just like her childhood story hero, Miss Rumphius. She spent some years working in various educational settings such as the Bird Alliance of Oregon, and then decided to pursue her graduate degree in Education at Portland State.
