Gretchen Klaubert
MUSIC TEACHER

Klaubert's journey in music education began long before she graced the classrooms of Mill Valley. Born and raised on the East Coast, she attended the renowned Hartt School, a performing arts conservatory that is part of the University of Hartford, in Connecticut. There, she pursued her undergraduate degree in vocal music education, laying the foundation for her future as a dedicated music educator.
Klaubert’s pursuit of musical excellence did not stop there. She went on to earn her master's degree at Oakland’s Holy Names University, specializing in Kodály Emphasis, a method that focuses on children’s choral training with the use of hand signs — a testament to her commitment to music education. Her deep-rooted passion for teaching music has spanned over two decades, with nearly a decade of those years dedicated to nurturing budding musicians at Neal Cummins Elementary in Larkspur.
Believing music to be a transformative art form that connects people, provides an emotional outlet, and spreads joy and peace, she simply concludes, “For kids this age, I want music to be fun.”

Julie Leonard
ART TEACHER

Art Teacher Julie Leonard has taught at Mill Valley Middle School since 2000, but she was familiar with her classroom well before that – she did her student teaching here as well!
Born and raised in Philadelphia, Leonard graduated from Tyler School of Art with a degree in Fibers and Fabric design, working in costumes and wardrobe for the television and film industries after college. Leonard discovered her love for teaching while volunteering with at-risk youth in an after-school program. She returned to school herself, and got her teaching credential in art from Sonoma State University.
Leonard loves working with middle schoolers; in particular, she loves their energy and enthusiasm. Of her work at MVMS, Leonard says, “I’m so grateful to be in a community that supports the arts. I love interacting with the students as they create – I learn as much as I teach, and I laugh so hard every day.”
Leonard's teaching inspires her students to think creatively as well as critically about their art. She encourages them to stretch their ideas and use new materials and techniques. It’s important to her that her students can go outside their comfort zones and take chances with their learning, in a safe and fun environment.

Katie attended School of the Arts High School in San Francisco (now the “Ruth Asawa School of Art”), where she developed her technical skills. She went on to study Art with an emphasis in Painting at University of California Santa Cruz. It was during her time at UCSC that her eyes opened to the world of art, and she learned to use art as her voice.

Ms. B grew up in Hudson, Ohio and comes from a long line of artists. "Art was not just a hobby, but a way of life in my home," says Ms. B. "I have continued this tradition with my own children. Art is our go-to activity to energize our spirits and feel alive!"
She describes her teaching philosophy as inclusive, and wants each student to take risks while learning about themselves through artistic expression. "In my classroom there is no right way to do art," asserts Ms. B. "As long as you are expressing yourself and learning about new mediums, your voice will show through!"
