Head of School

Brenda Leaks

Phone: (206) 709-2228, Ext. 1120

B.A., Spanish and Secondary Education, Notre Dame of Maryland University
M.S., Educational Leadership, Columbia University

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.

Why I love middle school: In middle school, students learn so much about themselves.  It is a fun, but challenging journey.

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!

Why I love middle school: What I love most about teaching middle school students is that they challenge me to be a better educator. Their needs change on a daily (or even hourly) basis, and I love the task of figuring out how to empower them to become successful learners. Being a part of the ‘aha!’ moments when students realize that they are their own best advocates on their educational journey is satisfying and exhilarating. Plus, middle students are just plain fun to be around. They exude a frenetic and contagious energy – they are funny, full of drama, and yet serious and thoughtful about their world, too.
