At the end of every school year, I reflect on my takeaways, my areas of growth, and how I can continue to grow as an educator. Returning to in-person teaching last year presented a lot of challenges and opportunities for me, including the opportunity to step into the role of an administrator. It felt invigorating! It was not always easy, but it opened my eyes to a role that I hadn’t previously been ready to consider. I have finally reached a point in my long career as a teacher in which I feel ready to take steps in a different direction, one that will allow me to lead in a community that I love. After teaching for 20 years, deciding to step out of the classroom was daunting, but I’m ready! I am ready to help bring more joy and enthusiasm to our school while maintaining the same high expectations I’ve always had for our students.

I look forward to serving in our community as a Dean of Culture and Instruction with the same passion I had for teaching, the support for parents and guardians as a parent myself, and authenticity as a proud Latina and lover of education!

Hello! I am incredibly excited to be a part of the Summit Tamalpais family as their Dean of Expeditions! Originally from Bismarck, North Dakota, I graduated with my BA in English before heading to the Bay Area where I received my MA in Education. I have been with Summit Public Schools for four years, the last three of which I have spent on the Expeditions team where I have not only taught Creative Writing & Short Story Composition at five of Summit’s California high schools but I also acted as an Independent Learning Coordinator at Summit Shasta this last school year. I feel so fortunate to have been able to be a temporary presence at Summit Tamalpais these last three years and so I cannot wait to be a more permanent fixture there moving forward.
