Nisa Frank appointed Prospect Sierra’s 3rd Head of School

October 2018

Dear Prospect Sierra Community:

The Board of Trustees is delighted to announce the appointment of Nisa Frank as Prospect Sierra’s third Head of School, beginning July 1, 2019. After an extensive search process, the Search Committee gave the Board a resoundingly affirmative recommendation for Nisa to lead the school forward and the Board accepted the recommendation with equal enthusiasm.

Nisa captured the hearts and minds of so many in our community. We are confident that her warmth, talent, and authentic leadership will guide Prospect Sierra through the next phase of our evolution as an independent school leader. Nisa brings a child-centered focus and lifelong passion for education that unequivocally inspires students, families, faculty, staff, and administrators. And as one community member reflected, “She seems to be exactly the kind of person I would hope we would have in charge of the school. She understands where we are as a school and community, and has a firm foundation and the experience to take us in the right direction.” We know that Nisa will help us continue to foster deep intellectual engagement in our classrooms, encourage self-knowledge and empathy with one another, and make change in this ever complex 21st century.

As a Bay Area native, Nisa comes from a family of educators, and her experience as a teacher and administrator in independent school education is both impressive and broad. Currently in her fifth year as the Head of Lower School at The Hamlin School in San Francisco, Nisa also serves on the boards of Aspire Public Schools and the Bay Area Teacher Training Institute, where many of our Prospect Sierra assistant teachers continue their education and training.

Prior to her tenure at The Hamlin School, Nisa was the Assistant Head of Preschool and Lower School at Packer Collegiate Institute in Brooklyn, New York. Nisa taught 2nd grade for seven years at The Town School in New York, NY, where she also served on the Board of Trustees before becoming the Director of Admission at Waterside School in Stamford, Connecticut. Her board level experiences and administrative knowledge will be significant assets to Prospect Sierra as we look to build upon a financially vibrant future for the school.

Nisa holds a B.S. in Child and Adolescent Development from San Francisco State University, an M.S. Ed. in Early Childhood Education from Bank Street College of Education, and a M.S. Ed. in Private School Leadership from Teachers College at Columbia University (Klingenstein Center).

This appointment is the culmination of a thoughtful and thorough search conducted over the past ten months. The Search Committee, with the support of Brigham Hill Consultancy, considered an impressive number of candidates from around the country. We were able to attract such a remarkable pool of candidates because of Prospect Sierra’s reputation in the national independent school community, the high regard with which Katherine Dinh is held in that community, and the exciting opportunity presented by our school. In accepting her appointment, Nisa said:

“Prospect Sierra is an incredible place. I saw first hand the profound commitment to a mission that sees the true value in cultivating the whole person, as a means to driving deep academic engagement. From the moment I entered both campuses, I could feel that the people, both children and adults, felt at ease, engaged, and real. The school’s mission was further brought to life by the students who sat with me at both Avis and Tapscott. They were kind, joyful, deep thinkers, and comfortable in their own skin. I am honored by this opportunity to lead Prospect Sierra and can’t wait to meet all of you.”

We want to thank all the members of the Search Committee, whose dedication, thoughtfulness and love of Prospect Sierra resulted in the appointment of such a superb choice to succeed Katherine Dinh. Thank you also to the faculty, staff, students, trustees, parents, and alumni for your time and insights.

As we settle into the remaining school year, Nisa will have opportunities to visit Prospect Sierra before officially beginning on July 1, 2019. In the meantime, please join us in extending Nisa a warm and heartfelt welcome to the Prospect Sierra community.
