Kate notes that many Montessori principles can be applied not only to developing children, but to directly benefit people at work and in life at almost any stage. When we meet people where they are, foster independence and intrinsic motivation, always with grace and courtesy, then we all have the opportunity for successful and meaningful lives. Marin Montessori School was a natural fit for her children’s education.

After two decades as a professional chef and baker in fine dining and casual settings in Kentucky, Washington DC, Buenos Aires, Manhattan, and Antarctica, JEFF GOSSETT became his newborn son Gus’s primary caregiver when his wife Amy’s job took them overseas to Spain. In Madrid, Jeff had the wonderful opportunity to share his passion for sourdough bread-making, which he had honed at Sullivan Street Bakery, with the eager young students at Gus’s first Montessori school set in a lovely old house. He relished helping prepare the school's daily vegetarian lunches while always looking to fix whatever needed repair that day. He led rooftop garden lessons with the students and learned more about the Montessori pedagogy while catering an annual All Spain Montessori educators’ conference.
Experiencing the beauty and purpose of the Montessori method deeply influenced Jeff. It ignited a love for volunteering, as a way to contribute and find community, which continued throughout Gus’s eight years at MMS. Jeff was excited to dive into any MMS initiative, including leading creative expression classes at the Junior High, and is honored to continue to work with the creative, warm, and welcoming MMS community as a Board member. Jeff, Amy, and Gus, now attending The Bay School of San Francisco, live in the Marinship area of Sausalito.
FRANNIE POPE-HOHMAN has called MMS her community since she and her family moved here from Seattle in 2005. Not knowing anyone in the area was potentially a scary transition, but Marin Montessori welcomed all of them with open arms. Frannie threw herself into every volunteer opportunity the school had to offer. Very quickly, lifetime friends were made not only by Frannie and Robert, her husband, but also by her sons, Oliver and Elliott. From ages five and three respectively her children grew up at MMS. They continued their education all the way through Junior High with Oliver staying for 9th grade. Their best friends to date are all still MMS students.
Frannie continued to volunteer in the classroom long after her children left lower campus. Being a classically trained actress from Boston University and working as an actress for 15 years, Frannie put her skills to use first by helping various directresses with their class plays and finally becoming resident play director in the Great White Egret classroom for the past seven years.
In addition to being active in her family’s daily life, Frannie is passionate about Social and Criminal Justice. She is a facilitator for a Victim Offender Education Group at San Quentin Prison. She welcomes any discussions or questions about the work and hopes to bring interest and awareness to her beloved MMS community. Frannie lives in Tiburon with her husband and two children.
