Joined Mount Madonna School in 2019

"I'm looking forward to teaching again within a school that emphasizes values-based education. It was important to me to find a community of people who care about each other and strive to be accountable to shared values. In Mount Madonna's mission statement I was especially drawn to the acknowledgement of the "transformative power of the creative process". I hope to make the art studio a hive of collaboration, experimentation and critical thinking - a place where students can discover, navigate and harness this power for themselves. I aim to foster an art studio culture that emphasizes growth mindset thinking. I believe art-making should be joyful and sparked by curiosity, and it should also be a place to practice persistence, adaptability and problem-solving. I'm really looking forward to getting started and seeing what the MMS students bring to the art studio and each other."

"When I accepted the teaching position offered to me by Mount Madonna School, I anticipated an environment in which individual teachers and learners would be recognized for our strengths, supported in our growth and challenged to expand our roles as global citizens. I have not been disappointed! I feel academically stimulated and personally fulfilled in this family-oriented community of learners. The school administration sets a tone of high expectations and responsible delegation for faculty and students, inspiring in me a sense of empowerment and commitment to the school's three pillars: academic excellence, creative self-expression and positive character development. I am honored to share my passion for lifelong learning with the Mount Madonna School community."

"I am thrilled to be working at Mount Madonna because it is a particularly nurturing and loving environment.  As a First Grade teacher, I strive to make learning fun, exciting and meaningful. I do this by teaching thematically and infusing a great deal of music and art throughout our curriculum. Teaching first graders to read and write is not only a huge responsibility, but is extremely rewarding!

I care deeply for my students and fostering meaningful relationships. I hold social success in as high esteem as I do the academics. I am honored to join the staff at Mount Madonna, where I can be surrounded by others who are as passionate about their work as I am."

Danielle Barr, B.A.

Preschool Teacher

B.A. Speech and Communication Studies, San Francisco State University , San Francisco; Montessori Northwest, Portland/Milpitas Primary Guide Credentialed

Joined Mount Madonna School in 2020

"I deeply value that Mount Madonna School offers an environment that nurtures curiosity and exploration and fosters independence and individual creative self expression. I commit to staying aligned with these values by guiding the children to find and recognize their place in community and their greatest potential. I believe it is important to learn early on compassionate ways of communication and the ability to nurture relationships, while staying open and true to possibility. My role is to guide and inspire each child's innate curiosity and facilitate their natural development of focus and concentration throughout, what Maria Montessori named, "The Absorbent Mind" years. I'm inspired by her philosophy to support each child in discovering the key that unlocks their individual treasure.

I was born with a love of learning and my personal vow is to never stop looking at the world through the eyes of a student because there is just so much more to discover. I am so grateful to share my passion for a lifelong love of learning with the children of Mount Madonna School."

Joined Mount Madonna School in 2021

In that time I also worked with Youth Empowerment Seminar, a socio-emotional program which incorporates breathwork, interpersonal skills, and mindfulness. I strive to honor the unique learning needs of every child I work with. This means integrating multiple approaches to teaching into the daily program to optimize each child’s success. As people around me know, I am especially passionate about the importance of cultivating creativity. I believe creativity not only improves our sense of well being but that creative people will be in high demand in the world of tomorrow."

It is part of us and we are part of it."

M.S., International Relations and Global Development, Universidad De Granada, Granada, Spain; B.S., Health Science Education/Minor in Nutrition Science, University of Florida, Gainesville, Florida

Joined Mount Madonna School in 2021

"I believe that making art moves mountains and creativity climbs higher than any challenge life can toss our way. It was while working for 15+ years in non-dance or necessarily art-based disciplines, that I saw something I couldn't un-see. What my career journeys into healthcare, research, management, sports and international relations, continued revealing to me was the tremendous power of arts and languages to heal, transform, unify both individuals and communities.

I’m here at Mount Madonna School (MMS) to teach Spanish and dance but that’s only part of the story. AT MMS, I’m a member of a learning community that values creativity and curiosity and supports students to be lifelong learners. Through collaboration with my learning community team, I expose students to a dynamic array of ways that dance, performing arts and foreign languages skills can be danced, spoken, loved, enjoyed and transferred into life."

Re-Joined Mount Madonna School in 2017

"Mount Madonna Center and Mount Madonna School (MMS) have been integral parts of my life for more than 30 years. I had the privilege of being in an adult version of THE RAMAYANA in 1990 which included several MMS students. Meeting them, seeing how creative and self assured they were, helped me make the decision to send my son, Jeremy ('07) up the mountain to school!. I began teaching music and performing arts in 1994. As a teaching artist, I love to share my passion for performance and process with my students. This year we are revamping the performing arts program in response to the pandemic. I am excited to see all the ways our creative spirits can carry us forward."

"I want to work at Mount Madonna School because I share its commitment to teaching the whole person, where the development of the whole person is intellectual, creative, and moral. I also share the School's commitment to social justice and the values of a democratic society."


Haley Campbell ('02) , M.A.

Joined Mount Madonna School in 2014

Mount Madonna School Graduate, Class of 2002

"The culture at MMS is so unique because there is such a strong emphasis on academic excellence, but it’s equally balanced with love and support. Today’s educational philosophies highlight the importance of educating ‘the whole child,’ catering to the intellectual, emotional, psychological, physical, and spiritual needs. MMS is the embodiment of the ideal. I knew it was an amazing place in my twelve years as a student, but as a teacher, it’s an absolute dream to teach at a school like this where you have the freedom to honor your students as individuals.

I have always loved reading, writing, and storytelling. I think these are such powerful ways to engage with the world, to ask the big questions, to explore new perspectives. I grew up on the mountain as an only child and spent a lot of time wandering through the woods narrating stories in my head. To me, literature is as much a sage guide as a friend or therapist – we can learn so much about human kind, nature, and ourselves by engaging with a good story."

Hilary Alvarado, Ph.D.

Middle School Math and Science Teacher

Ph.D. Environmental Studies, University of California, Santa Cruz; B.S. Natural Resources and Environment, University of Michigan, Ann Arbor; Single Subject Teaching Credential (Science)

Joined Mount Madonna School in 2018

"Math and science give students a new language to observe the world and understand how it works. I love teaching middle schoolers these subjects because middle school is a time of self discovery.  During this time, students often decide if they are or are not a 'math person' or a 'science person,' and they are starting to make decisions about their future. It’s my job as their teacher to make math and science accessible to them and to make sure all students believe that they can (and will!) learn these subjects. I believe that middle school science and math should spark curiosity, imagination, and  inquiry, which is fostered through hands-on activities and real world situations. Mount Madonna School’s campus and its surrounding environment create an ideal outdoor laboratory that lends itself to hands-on exploration and observations of the natural world."

"With an open mind & heart, I hope to invite children & adults into learning through inquiry, curiosity, & exploration. I strive to create opportunities for experiential learning through the mind and body. It is my honor to build learning communities of respect for the earth & for all people through stories, play, nature, art, music, movement, and imagination. I am excited to work at Mount Madonna as it is an alternative education program that is balanced in approaches such as its Montessori and Waldorf influences as well mindfulness, yoga, and anti-bias curriculum. I hope to share my passion for social and environmental justice with age-appropriate content. As a guide to children in their learning adventures, I hope to be a caretaker of wonder."

Joined Mount Madonna School in 2002

"I chose to teach at MMS because I was looking for a school where I could teach while pregnant with my first child, that embodied my educational philosophy. I believe that teachers and education act as a mirror and a window. I believe my teaching should help children to see and find themselves and look into others' perspectives. MMS presents the teacher with an arena to do just that! After my hiatus to raise my family I returned to MMS because I knew after that first year that this was the only school I ever wanted to teach at and the only school for my children to attend. I have never experienced such genuine love, support and care from any other teaching environment!"

As an educator, mental health therapist and facilitator, I am committed to projects that celebrate uniqueness and model compassionate communication.  I joined Mount Madonna School because of its’ emphasis on a balanced approach to education which includes students emotional well-being and sense of belonging. I have witnessed how the Performing Arts Program pushes students to act with courage, building confidence and trust in the support of their community. As a student and later an environmental educator, many of my own transformative experiences have come while in the natural world.  Mount Madonna School is nested in the hills, engaging our connection to nature, which supports personal responsibility and stewardship of the planet. I am so looking forward to diving in with the students to build a Life Skills Program that sharpens the tools needed for caring behavior towards self and others."

Joined Mount Madonna School in 2021

"I love helping students discover the amazing world around us, make connections, and become mature thinkers. I enjoy and teach the processes of 'finding things out' and I strive to help students develop their agency, curiosity, and scientific literacy, rather than focusing on collections of facts. I'm excited to teach at Mount Madonna School because the school sees students and staff as whole people and global citizens, and the small class sizes allow for rich educational dialogue. Previous to MMS, I coordinated the physics teaching laboratory at Cabrillo College for 20 years. I have a varied background that includes teaching preschool, welding bells and bike trailers, working at NASA, teaching outdoor skills and natural history, helping build houses with natural materials, playing music, and traveling extensively in Latin America."

The outdoor environment at MMS is the kind of atmosphere that just doesn’t exist at other schools.

From a very early age I have always been interested in the uniqueness and complexities of our world and have challenged myself to continually learn and discover it whether that be through travel, extended learning, or just building relationships through community action. I hope to impart that desire to the students at MMS by developing an interest in not just the semantics of learning a new language but also a focus on history, art, music and literature.
