Second Grade Teacher
Jennifer’s passion for working with children began with her job as a camp counselor in high school and college. It gave her great joy being outdoors with children, delighting in all that nature has to offer. After many summers of canoeing, hiking, archery, singing, skits, games, art projects and having received a BA in child development from Sacramento State University, she decided to pursue a teaching credential. Once completed, she taught kindergarten for 12 years in Fairfield and loved it! After her third child turned one year old, she decided to stay home. While home, she found a second career as a Clinical Coach for Touro University. This gave her the opportunity to mentor teachers working to get their teaching credential.
Jennifer is beyond thrilled to be heading back to the classroom at this most amazing school! Waldorf education matches her belief that education should be engaging, well rounded, developmentally appropriate, teach the whole child, and most importantly be filled with love and care for one another and our Earth.

Martha holds a Masters in Early Childhood Education from Virginia Tech and is enjoying expanding her Waldorf knowledge as a class teacher at Stone Bridge. She loves being outside with the students, moving and singing to keep each day exciting and full of joy.

Julia U’Ren first learned about Waldorf education as an undergraduate at UC Davis where she studied both Rhetoric and English. She enrolled in UC Davis’ credential program upon graduation and began teaching full time that same year in a 7th Grade Language Arts classroom in South Sacramento.
Her three years teaching culturally and linguistically diverse children inspired her to earn a Master’s Degree in Educational Thought and Socio-Cultural Studies, this time from the University of New Mexico in Albuquerque. After graduate school came more middle school teaching, marriage, and three children of her own. Julia found herself thinking about Waldorf education once again. As she filled out the application to enroll her oldest daughter as a Mulberry Kindergarten student at SBS, she added a note that read, “I think I might want to teach for you one day," and if things haven’t changed…
As a Napa native and longtime area educator, I’ve had the honor of contributing to the incredible human journey of many in our community through varied roles and across generations. My education and interest spans art and music, commercial design, literature, mythology, sociology, and psychology. While I am proud to have academic success, I am also dedicated to applied learning as it relates to expanding experience, character, and conscious growth of the individual and our society for the benefit of the public good. I have been a teacher, transformative coach, and administrator in service to these goals, and am excited to continue with that work for many years to come.

Movement 5th - 8th
Wil Anderson has a background in human development from the Arica Institute. He also attended the University of Southern California and studied acupuncture at the Samra Institute. In Los Angeles, he was co-owner of Pyramid West, a nonprofit business focused on personal growth and understanding the human process. Soon after moving to the Napa Valley in 1987, he opened the Veranda Club Spa in Yountville which thrived for 22 years. Wil has spent 50 plus years organizing group trainings for industry workers and military veterans in methods and techniques that uplift the human condition across the human spectrum.
It was during his marriage that he became aware of Rudolf Steiner. Steiner's perspective on the child and the deep respect that should be accorded impressed him. He found Steiner's ideas about how Waldorf teachers should present themselves most fascinating. The idea of the teacher being a guide and not an imposer appealed to him.
Wil is the father of five adult children who all attended Waldorf schools in their youth. He was thrust into a leadership role as the president of the Napa Valley Waldorf Education Foundation in 1997. This organization provided the foundation for what is now Stone Bridge school. It was George Hoffecker, a Waldorf Charter School developer--dear mentor and brother--who inspired Wil to continue contributing to the evolutionary process of SBS.
Wil found that bridging his work and the Steiner method was a harmonious process. He was further assisted by Edmond Knighton (President of the Steiner Waldorf College) who had authored several texts on how to instruct movement classes and how to teach archery, javelin and discus. Edmond led several Movement Teacher Trainings, which Wil was fortunate to attend. The blending of Wil's past training/teaching skills and the Waldorf games trainings work well together to create a healthy Movement program for SBS.
Handwork 1st - 8th
Maria Giusti is the Handwork Teacher/Director for Grades 1-8. She has worked at Stone Bridge School for over 18 years - 13 years as a class assistant and the most recent five years teaching Handwork. When she first came across Waldorf education 20 years ago, she knew it was the right fit for she and her sons. Teaching and learning through head, heart and hands was very much how she experienced all of life.
Maria learned knitting, sewing, embroidery, gardening, cooking, building, and many other life skills from her family as a child. Not only did she want these experiences for her own children, but she was eager to bring such skills to others as well. Over the past 15 years she has studied Waldorf education at Steiner College and through various Handwork Conferences and other coursework. She is grateful to combine her love of creativity and fiber arts with a deep desire to do purposeful work through Waldorf education.
Woodworking 5th - 8th
From an early age, as far back as he can remember, Greg was a tinkerer. He would spend countless hours at his father’s workbench creating, inventing, discovering. No wonder then that in 2016, Greg (aka “Mr. G”) would become the woodshop teacher here at SBS, bringing his creative and inventive spirit to the students. “I love working with wood, how it can be transformed by our head, heart and hands – indeed, how our head, heart, and hands can be transformed by it!” Greg has a B.S. in Biology, three lovely children, two of whom attend SBS, and a very patient wife!
Farmer 1st - 5th
As far back as Farmer Chris can remember, he's always been an "outside" person. Growing up on a family farm not far from the SBS Campus, his love of the outdoors seemed pre-destined. "Some of my favorite memories came from that farm. Splashing around in the creek, climbing the unimaginably huge oak trees, caring for the horses, sneaking fresh carrots right out of the garden."
After graduating from Sonoma State University with a degree in Environmental Studies and Planning, he worked in viticulture for several years before finding his true calling in the classroom ... or more accurately, the Farm. Since 2015, Farmer Chris has overseen multiple Elementary School Garden Programs at various schools throughout the Napa Valley. In August 2019, Farmer Chris became the Farm Instructor and Farm Manager at Stone Bridge School.
His passion for the unique opportunity that outdoor education provides has found a home on the SBS Farm. Farmer Chris views the SBS Farm as not just a place to grow plants, but rather a "living laboratory" primed for student investigation and inquiry.
In his free time, Farmer Chris can usually be found, no surprise, outdoors. His hobbies include fishing, hiking, camping, kayaking, gardening, nature photography, music and cooking.
Math 6th - 8th
Laura was born and raised in the Napa Valley. Looking for a "big city experience," she moved to Los Angeles and attended the University of Southern California where she earned her bachelor's degree in Civil Engineering. Deciding Northern California was more her style, she moved back to the Bay Area to work as a Project Engineer. During this time, she encountered Rudolf Steiner's ideas regarding farming while her husband worked at a biodynamic winery in the Santa Cruz mountains.
Fast forward a few years, Laura returned Napa where she and her husband were raising their two young boys. While looking into school options, she discovered Stone Bridge School! This was her introduction to Steiner's ideas regarding education. Excited to become involved in the SBS school community, Laura started substitute teaching, then took on the role of Assistant Teacher to the class of 2025, from first through third grade. When the Middle School Math Teacher opportunity opened up, Laura was so excited to share her passion for math with upper grades students. Laura strives to prepare her students for the rigors of high school while keeping math class fun. She puts great importance on helping students understand that there is never just one way to think through a math problem and enjoys helping students discover how math is all around them!

Upon electing a separate college path, Jane earned a B.A. in Psychology from Pennsylvania State Universtiy then ventured further wesward to Columbus, Ohio, where she eventually completed the graduate program in Developmental Psychology at The Ohio State University (OSU). During and after grad school, Columbus, Ohio offered a wealth of opportunities in teaching, research, and administration. Jane taught psychology courses at OSU and Franklin University.

As the current Games teacher and Educational Support Specialist, Tony is enjoying the opportunity to help students both academically and emotionally. When he is not on campus, Tony is typically found with a book in his hand or kitty on his lap, or as one of his favorite poets put it, “Books. Cats. Life is good.” (T.S. Eliot)
Capucine de Swarte Sturmer
Capucine was born and raised in France, where she spent a happy childhood enjoying the Parisian city life, exploring museums during the week and a more “down to earth” life during weekends and school vacations. She loved exploring the woods and respecting the nature, a passion that her father shared with his children. She traveled a lot through France and Europe with her family and later with her husband.
Before finding her true vocation in early childhood education when she became a mother, she studied law at University Paris V, worked for a private equity firm, and a law firm in France. Always very interested and passionate about the wine world, she worked at Robert Mondavi Winery when she moved to the Napa in 2012, educating visitors about winemaking and tasting.

Trying to advocate for young children and make a difference, she opened her own daycare creating a nurturing, loving and safe environment where young children could be themselves and develop their personality and milestones at their own pace.
For her joining SBS is taking the next step into making a difference in this world and be part of a community that cares about the world in general, one another, and especially about young people.

Karla enjoys spending time sewing, painting, gardening, traveling, reading, hanging out with her family and pets, and being a stage mom to her youngest child.
Eric grew up in Napa, a stone’s throw away (no pun intended) from the SBS campus. He graduated from SFSU with a bachelor’s degree in clinical psychology and worked for Suicide Prevention at the Institute on Aging for 20 years.
Eric lived in San Francisco for 28 years, loving it immensely. He spent years attending the San Francisco Zen Center. He was also deeply engaged in underground theater as an actor, in addition to embracing bicycle culture and learning how to live without a car. Ten years working with the folks at the San Francisco Department of Elections was also a very fun side gig.
Eric returned to Napa in 2015 and has been part of Stone Bridge School’s Aftercare team since 2016, joining his friend of over 35 years, Karla Bunter, our Aftercare Director. Eric’s father was a pediatrician, and Eric recognizes that he echoes his father’s deep care for children in his own daily work with the students at SBS.
