Brenda has worked in independent middle schools across the country. In Philadelphia, Brenda worked with Breakthrough Collaborative, a non-profit focused on helping low-income students move from middle school through college, which was housed at local independent school Germantown Friends School. Brenda then taught middle school Spanish and worked on diversity initiatives at The Baldwin School, an all-girls PreK-12 independent school, and The Shipley School, a co-ed PreK-12 independent school. After completing a graduate school program focused on private school leadership at Teachers College Columbia University, Brenda moved to Austin, Texas to become the Middle School Head at Trinity Episcopal School of Austin, a K-8 independent school. An opportunity to be the Middle School Head at The Overlake School, a 5-12 co-ed independent school, in Redmond brought Brenda to the Puget Sound. She is excited to now be the third Head of School at Seattle Girls’ School.
Why I love middle school: Middle school is an exciting time in a student’s life when the main constant is change. There are so many parts of oneself to discover and explore; it’s possible to end up just about anywhere. While that idea may seem daunting or a bit chaotic to some, it is the joy of middle school. Our girls are working hard to become themselves in all areas of their lives: as students, friends, activists, daughters, athletes, thinkers, artists, community members and more. And, while we don’t know exactly where they will each end up in each of the many facets of their lives, we value the journey because we get to see them learn, laugh, and courageously face and overcome obstacles. Our girls awe us daily as they grow and teach us moment to moment what possibility looks like.

Barbara began teaching in 1997, and since then has worked in public and private schools in San Francisco and New York City. Most recently, she was Divisional Director at Greene Hill School in Brooklyn, NY, where she had the rare opportunity to create a new progressive school program spanning ages four through fourteen. At Greene Hill, she was instrumental in creating a flexible curricular framework and school culture that supported deep and purposeful learning. Barbara joined Seattle Girls’ School in 2014, and is responsible for ensuring that students (and teachers!) are engaged in meaningful work that challenges each of them intellectually and creatively. Barbara believes she has the best job in education, one that allows her to get deeply involved in the nitty-gritty of classroom life, and also to step back and see how all the pieces fit together to support the wide-ranging needs of middle school girls. She is thrilled to be at Seattle Girls’ School, and never imagined all those years ago that her Math and Women’s Studies double major would ever feel quite so practical!

Why I love middle school: What’s not to love about middle school? It’s a time of exploration, debating issues of fairness and justice, learning new skills, and not only thinking big about problems, but also trying to come up with solutions to those problems. I see such great promise in middle school students and feel very privileged to be part of the SGS community.

Why I love middle school: Middle schoolers are a goofy and awkward bunch — and I love them for that. I also appreciate middle school kids for their willingness to laugh, their natural curiosity, and their exuberance for all things science. I especially like teaching science to middle school girls because I can provide them with opportunities for traditionally “un-girly” experiences like (safely) setting things on fire, using power tools, and engrossing themselves in an array of slimy and stinky stuff. In a single-gender middle school science classroom, the girls have to be the ones to take all of the chances because there are no boys to defer to like they often do in mixed-gender classrooms. Not at SGS!

Why I love middle school: Middle school is this magical time where young people are optimistic and innocent AND ready to think about tough and abstract topics. It is a time when they are both able to follow the rules AND challenge their fairness. Middle school youth can share with you the most mind-bendingly deep thought one moment and then hang upside down on the monkey bars like a six year old the next moment. They’re like New England weather – wait five more minutes and you’ll see a whole new side to them! They’re such passionate, curious, challenging, and interesting people; it’s a mystery to me that everyone wouldn’t want to work with middle school youth!
