Biography
Andrew believes in the potential for education to be transformative and empowering for all students. He developed and led international and U.S. education programs and taught students from 10 different countries. He also experienced the full breadth of public and private educational institutions, working with early childhood through undergraduate, graduate, and adult learners. All of his work is geared toward providing empowering, culturally sustaining, learner-centered, anti-bias, antiracist, and equitable education to students around the world.
Andrew attended a Montessori school himself through Upper Elementary, which is why he returned to the method as a teacher. He opened two Montessori adolescent programs as a founding lead teacher at the middle and high school level. In those roles, Andrew most enjoyed building deep relationships with students, creating a holistic humanities curriculum, and collaborating with adolescent practitioners across the country.
In addition to his work at Oneness, Andrew is the Co-Host of the Breaking the Paradigm podcast and an Affiliate Instructor of Montessori Teacher Education at the graduate level at Loyola University. He holds a Masters in International Educational Development from the University of Pennsylvania Graduate School of Education, a Bachelors in Anthropology from the University of Rochester, an AMI Adolescent Diploma, a micro-certification from Embracing Equity, and a certificate from the Phillips Exeter Humanities Institute.

She graduated magna cum laude as a member of Phi Beta Kappa from Bowdoin College with a major in Francophone Studies and a minor in English Education. In 2025, she completed Bowdoin’s intensive teacher-training program as a postgraduate to earn a teaching certificate in secondary English.

Professionally and personally, Jilly is drawn to self-expression in all its forms, including language, art, music, and literature. As a Humanities Teacher, she wants to help students find and hone their voices by building in opportunities for them to hear and share stories, especially those that are traditionally marginalized or silenced.
As an undergraduate, Jilly worked at Upward Bound to provide underserved high schoolers with the tools to become first-generation college students. Also at Bowdoin, she worked as a teaching assistant and completed a French independent study on post-colonial discourse and curriculum. Her love of mentorship extends back even further: in high school, she worked for the Girls’ Leadership Institute to help middle-schoolers develop leadership skills and build service-action plans. As a long-term Girl Scout, Jilly earned her Silver and Gold Awards, which focused on sharing the healing benefits of art and nature.
Jilly is passionate about empowering those in her care through shared respect, wonder, and a heaping cup of joy. She is excited to join the Oneness-Family community this year!

Debbie Kahn
American Sign Language (ASL) Teacher
Email
Biography
Debbie’s career journey is like a winding road trip through diverse landscapes. She began as a computer programmer in a bank but shifted gears to become a Montessori teacher and later the Associate Director at the Oneness-Family School (1992-2009). She then took a sharp turn and ventured off-road to travel to Niger with the nonprofit Amman Imman: Water is Life as the Associate Director, where she inspired students to assist indigenous populations affected by climate change, desertification, and water scarcity.
In addition to her professional pursuits, Debbie has also acquired fluency in sign language through her journey. She learned sign language from her deaf housemate and quickly became her interpreter at local events. As a teacher at Oneness, she taught sign language to students and engaged them in fun performances at festivals and in-house events. Now, over a decade after “graduating” Oneness, she’s back on the road, teaching American Sign Language (ASL) at the high school level.
Debbie holds a Montessori teaching certification from 1992 and a B.A. in Education from Goddard College (2007). In her free time, Debbie writes poetry, enjoys hiking, and loves exploring the wilderness with dogs and kids of all ages.

Biography
Brian was born and raised in Seattle, Washington, and loved that he could explore from the oceans to the mountains. He worked as a veterinarian assistant, helped manage a Bed & Breakfast, guided whitewater rafting trips, and worked on a team building and remodeling houses. Eventually he headed off to the University of Washington, where he received a Bachelor degree in Fine Arts with an emphasis in painting.
