TECA-SF Board of Education

The Thomas Edison Charter Academy Board of Education is composed of parents and community members who play a vital role in the governance of TECA. They ensure that the students in our school receive the best education possible. The board meets together regularly to make decisions regarding school policies, budget allocations, and educational goals.

Please Join Us

We generally hold our board meetings on the third Wednesday of every month at 6:00 p.m. Meetings are open to all TECA families and community members.

TECA’s collaborative policies, programs, and instructional framework have helped our community bring a vision of educational excellence to life. We are committed to including students, parents, teachers, and our community in our decision-making process.

Translation Services

The board strives to make board meetings accessible to all members of the TECA community. Although we conduct board meetings in English, language interpretation is available upon request. If you would like to attend a board meeting and require language interpretation, please contact (415) 970.3330 ext. 221 as soon as possible, but at least 48 hours prior to the scheduled meeting, and we will make every effort to accommodate your request.

Our Responsibilities

Under the requirements of the State Board of Education, the TECA board is responsible for ensuring that the school:

  • implements the provisions of its charter as approved;
  • obeys all requirements of federal, state, and local law that apply to the school;
  • operates prudently in all respects; and
  • provides a sound education for all of its students.

About Joanna Powell

Board member since: September 20, 2017
Term expires: September 30, 2020

Joanna Powell grew up in Southern California, where she had the good fortune to attend rigorous elementary and secondary schools that prepared her for a lifetime of learning. She then moved to the east coast to attend Yale University and graduated cum laude with a B.A. in political science. After college, she became a second grade English as a second language teacher in the Bronx through Teach for America. 

Joanna left the classroom and enrolled at NYU for law school, where she focused on education law and policy. Following law school, she moved back to California, where she clerked for a federal judge and practiced education litigation at a big law firm. She now works as a school attorney at Fagen Friedman & Fulfrost LLP, where she works on litigation, special education, and labor and employment issues. She also volunteers as a tutor with SMART.

“My time as a second-grade teacher in the Bronx instilled in me the belief that all children can learn, and I’ve dedicated my career to expanding their access to the educational opportunities that allow them to do so. I joined the TECA board because I live in the community and want to help ensure that the children in my community have excellent educational options. Thank you for welcoming me!”

About Ryan Hazelton

Board member since: April 11, 2017
Term expires: April 30, 2020

Mr. Hazelton grew up in San Diego, arriving in San Francisco ten years ago in pursuit of a career in online advertising technologies. After a few years and having previously worked in a welfare-to-work office out of college, Mr. Hazelton decided to leave the tech sector and pivot to a career in nonprofit. A new passion for education and building healthy families arose from a position fundraising for a nonprofit preschool focused on providing low-income and homeless families with early childhood education and family support services in the Mission District. Mr. Hazelton currently works in fundraising as the major gifts and individual giving officer at Safe & Sound, a nonprofit organization working to end child abuse and strengthen families in San Francisco.

Mr. Hazelton holds a bachelor’s degree in communications from the University of California, San Diego, and also sits on the board of directors at Tandem, Partners in Early Learning, to increase early literacy skills and family engagement programming in the Bay Area.

“Education is the great equalizer. I joined the board of directors at TECA because I believe all children deserve access to high-quality education in a safe and nurturing environment. When children are empowered with education and encouraged to be curious explorers of the world, the opportunities they have to better themselves and the community can be endless. And, when parents and caregivers can drop off their children in a safe and nurturing environment during the day, they can focus their attention on building and maintaining a healthy, stable home for the family to thrive. This is how we build a stronger and healthier community for us all.”

About Brenden Green

Brendan Green was born in Johannesburg, South Africa and spent his formative years in Indianapolis, Indian,a and London, England. The dichotomy in his schooling gave him a taste of how different cultures approach education in different ways. This began his lifelong interest in education and educational methodology, which culminated in him starting his own educational toy and digital media company while pursuing an MBA at the Wharton School. Brendan spent four years developing toys that bridged traditional and new technology to help children build skills and promote positive play patterns. In 2015 he and the company moved to San Francisco. While the kids loved the product, it was not meant to be and Brendan now leads global customer operations for a Bay Area-based technology company.

Education is the key that unlocks not only the opportunity but also creativity and wonder. Every child deserves a great education, not only because every child deserves equal opportunity, but also because every child deserves to unlock and fuel creativity and sense of wonder. It’s truly a great thing to expose a young mind to something new and watch the excitement grow. As a society, I believe we all must do more to nurture young minds and dedicate ourselves to support our teachers and the institutions, like TECA, who are doing so.
