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.

Outside the classroom, I love spending time in nature. I work at a summer camp in Maine during the summers, and in my free time, I enjoy hiking, kayaking, reading and playing basketball and soccer. 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

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 🙂

Hi, my name is Krystle. I found my love of working with children in 2012 when I was hired for a temporary position in a preschool classroom. Since then, I have worked with children of all ages within the daycare setting until 2017 when I was hired for my first job as a behavior coach.

I am very neurodiverse and have a passion for celebrating all forms of neurodiversity and building pride within that. I love being able to express myself in different ways and have multiple hobbies that I cycle through including different art forms (cross- stitching, painting, resin art, diamond art, drawing, etc), theater, watching football, and tabletop gaming. I also love to read, especially fantasy and horror novels. I am very excited to get to know my students and to help foster their love of learning and of themselves.

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. Sade joined the faculty in 2023 after being a stay-at-home mom, and student all while serving on the Cottonwood board and the DEI committee. Sade holds a Bachelor’s in Communication from  Portland State University  and an Associate Degree in Business Administration. She is excited to step into a new position at Cottonwood as the Director of Students, Culture and Belonging.

Sade believes every child from a diverse background should have someone advocating for them in the school system. 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.
