In Cedar’s teaching, generosity is a circle.
We give, we receive, we grow.
At Cottonwood, December brings us the teaching of Cedar –
a reminder of kindness, generosity, and the grace of giving
and receiving. Our students sing it in the Western Red Cedar
song: “If I’m living, then I’m giving.”
This season, we invite you to join that circle of care.
Your gift strengthens our community, nurtures our students,
and helps our school continue to grow.
Thank you for giving in the spirit of Cedar.

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’m also passionate about cooking. I’ve taken classes around the world and have taught cooking as a middle school elective. I love working with upper elementary and middle school students and I’m very excited to work with the community at Cottonwood.

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.
Before becoming a teacher, I earned a BA in Biology from Reed College where I was part of an animal behavior research lab. I also conducted research on the impacts that humans have on plant development. After graduating, I attended Lewis and Clark Graduate School of Education and Counseling, and earned a MAT
In my teaching, I love bringing in art, curiosity and creativity in order to connect science to students’ lived experiences. I am passionate about making science accessible so that my students are not only doing science but also feel like scientists themselves.
Outside of school, I enjoy spending time with my animals (my Labrador Lilah and my cat Louis), having game nights with friends and family, going to Thorns games, and working on my various crochet projects

Hi, I’m Jeff Winograd. I teach 4th and 5th grade at The Cottonwood School of Civics and Science in Portland. My classroom centers on story, inquiry, and hands on work with a strong sense of place. I share my own stories and invite students to share theirs; we keep things fun and a little silly while holding a clear bar for academic excellence. I believe we only learn when we make mistakes, so I build routines that are safe, kind, and focused on growth. I lean on the storyline method, which lets students build empathy through imagination and shared experience. I have been a strong proponent of place-based learning since my son started at Cottonwood eight years ago. Both he and my daughter, now in sixth grade, have attended the school for their entire schooling. In line with Cottonwood’s approach, I center Indigenous voices, histories, and perspectives to learn about this place and its rich, if complicated, history. I love science and look for chances to thread it through our work so we stay grounded in the natural world. I teach 4th grade math where I share my passion for the subject and find ways to tie it to the world around us. I am currently pursuing a graduate degree in elementary education at Oregon State University. When I am not teaching, you can find me listening to music of nearly every genre; DJing house and techno; walking the dog; or watching Chicago sports: Bears, Blackhawks, Bulls, and Cubs. I also started a daily meditation practice this year and even if you don’t ask me about it, I’ll probably tell you about it anyway.

Sade joined the CSCS community in 2017 when her oldest was in kindergarten at Cottonwood; now she has three children attending. Cottonwood’s place-based curriculum and passion for civic engagement was the foundation for putting her kids at CSCS.

Growing up, Sade lived all over Portland and Vancouver, and as a person of color, she understands first-hand how challenging a school system embedded in systemic racism can be. The experience of being unnoticed and forgotten by an education system rooted in systemic racism inspired her passion for DEI work. The passion she has for DEI comes from her own lived experiences and raising four black children in the public-school system. Her philosophy is that all schools should foster a culture of difference, hold individuals accountable for equity, and challenge preexisting notions and misconceptions. This work in making CSCS a more inclusive environment is something she believes the school is committed to doing. In her free time Sade enjoys writing poetry, listening to music, dancing, and spending time with her family.
