Sue Nadell Gintel
Executive Vice President & fundraising chair
Originally from Brooklyn, New York, I moved out to LA after college to be part of the entertainment industry. I’m now a full-time mom to a current Marshall sophomore and enthusiastic volleyball player. As Vice President of the PTSA, I look forward to interacting with local businesses to help raise funds for our school while promoting a strong sense of community. It is my goal and my passion to support the students, teachers and staff at Marshall so that everyone can enjoy the most rewarding and enriching school year possible.
Tim Boland
VP Communications
I’m thrilled to be volunteering with the JMHS PTSA! As a neighborhood resident for 25 years and a proud parent of a JMHS Senior. I’m excited to help strengthen our school community. I’ll be assisting with communications, promoting events and fundraisers, driving membership, and finding ways to make our wonderful community even more connected.
Sarah Briuer Boland
SECRETARY
Hi everyone! I’m a fiercely proud Angeleno and delighted mom of a Class of 2027 Barrister. I am also an anti-racism organizer, educator and facilitator, committed to honoring the inherent worth and dignity of all people. As Los Angeles network contact for Integrated Schools, I’ve learned that public education is how we achieve equity and bright futures for our own children, for all children and for democracy. That’s why it is my honor to serve the Marshall community as PTSA Secretary this year.

Jasmine Starr
Parliamentarian
Hi, I helped start the Marshall High PTSA to provide a way for myself and other parents to be more involved in supporting Marshall. We are lucky to have such a great school in our community, but its continued success depends on all of us pitching in. Being part of PTSA is a great way to stay connected to our kids at a critical time in their lives. It is also a fun way to connect with other families and the amazing teachers and staff at Marshall. I hope you’ll join us today!

I am a mom to a sophomore student-athlete at Marshall and a mom to a 7th grader at King MS. Born and raised in Wisconsin, I am a fighter for our public schools in Los Angeles. My husband and I help run an arts non-profit that provides in-school and after-school classes as part of the LAUSD Arts Community Network, and I am a math educator and curriculum specialist for 25+ years. I hope to continue to support the amazing families and students in our Marshall neighborhood.
Anne Edgar
Chair, Membership Committee
Nice to meet you! Before my son came to Marshall (he’s a Senior this year) I volunteered for several years for Marshall’s excellent program, College Path LA, and got to meet many graduating seniors. I have loved watching the Marshall community come together to help our kids grow academically and as human beings, and have found it fascinating and sometimes challenging to keep track of the many, many opportunities for Marshall students, teachers, families and staff. There’s so much going on!
This year I will be working hard to welcome new members to our PTSA and bring us all together. Every Marshall student, family member, teacher and staff member has a story to tell, tips to share and important observations to make about our school. I can’t wait to hear yours!

Originally from San Diego, I feel fortunate to have spent the last 34 years in Silver Lake.

It’s a pleasure to serve on Marshall’s PTSA alongside a wonderful group of people doing great things for our school and our kids. From hosting end-of-semester teacher & staff brunches to launching new community initiatives, I’m excited to continue building school spirit this year. Outside of PTSA, you can find me working in my garden or keeping up with my two boys—a freshman and a junior this year.
