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.
