Teaching for Change Board Members

Board Overview

The board meets every two months with the leadership staff to stay informed about the diverse programs, review finances, plan fundraising, and outline strategic direction. The meetings include programmatic-policy discussions and a due diligence review of finances and human resources. The board monitors Teaching for Change grant and contract obligations.

Current Board Members

Kate Tindle, Co-Chair

Board member since 1999
Senior Program Associate, Synergy Enterprises, Inc. 
As a child of a military family, Kate Tindle moved around every three years, being exposed to new communities and schools throughout her K-12 experience. This mobility fostered an awareness of how people can make others feel different and marginalized. Before her father was drafted into the military, Kate’s father worked at hanging wallpaper and pumping gasoline. Her mother, with five children, was a stay-at-home mom until cancer took her at an early age, when Tindle was seven. Tindle’s mother’s family, Irish immigrants from Cork to Baltimore, also shared a blue-collar background of plumbers, salesmen, and secretaries. This family background, coupled with transient school experiences, fostered in Tindle a desire to make a difference by pursuing teaching in high needs schools as her career. She tried to foster a sense of activism in her seventh grade students by teaching biology through the lens of how human behavior can impact living things and how political and legal action can help save environments. Tindle eventually moved into preparing graduate students at George Washington University to teach in high-needs urban schools and currently works for educational reform at Synergy Enterprises, Inc. In 2012, Tindle contributed a chapter to the book, White Women Getting Real about Race: Their Stories about What They Learned Teaching in Diverse Classrooms.

Sylvia Y. Sanchez, PhD 

Board member since June, 2014
Sylvia Y. Sanchez, PhD has had a long career in early childhood and bilingual education. She served as Associate Professor in the Graduate School of Education at George Mason University. There she co-founded UTEEM, a teacher education graduate level program that blended the fields of early childhood education, early childhood special education, bilingual/second language education, and multicultural education. This nationally recognized program prepared teacher candidates to work with culturally, linguistically and ability diverse young children and their families. Sánchez is known for her research interests in early bilingualism, diverse families, family stories, and professional development of teachers who work with culturally and linguistically diverse young children and their families. This commitment grew out of her personal experiences. As she explains, “I grew up in San Antonio, Texas with racially segregated schools, neighborhoods, religious institutions, and even segregated shopping areas. Language oppression was prevalent; it was against the law to speak a language other than English in a public building and children were routinely punished for speaking Spanish. Overnight, houses in my neighborhood would be boarded for long periods of time as migrant families followed the migrant stream up North. Migrant children dropped out of school at very young ages and no teacher ever spoke about them or questioned why they were not in school. In spite of these powerful local and state political forces, I grew up surrounded by a stable and loving extended family. We spoke Spanish at home. My grandparents lived across the street, and all of my eleven aunts and uncles and my large number of cousins lived no more than five miles away. This has shaped by belief in the powerful role of families, and the importance of supporting them.”
