Sonia Park – she/her/hers

Executive Director

Sonia is a daughter of Korean immigrants and the product of public schools. Growing up she moved frequently and attended many schools in and around Philadelphia. In some instances, she and her siblings were the only non-white students in the entire school. She directly experienced the possibilities and limitations that a zip code can confer.  She believes that the primary place that can bring people together – school – should be a space where students can develop understanding and empathy across lines of differences.  She believes that in today’s world, her son should not have to defend or define who he is.  She is striving towards creating that ideal. 

Sonia’s been working in education reform for over 20 years.  Prior to DCSC she served under Secretary John King at the US Department of Education as a Senior Policy Advisor and also was the Executive Director of Charter Schools Accountability and Support in the NYC Department of Education under Chancellor Denis Walcott. In addition to leading Manhattan Charter Schools, a two-school charter network located in lower Manhattan, her work experiences include the National Foundation for Teaching Entrepreneurship, NY Charter Schools Resource Center, NY Charter Schools Association, and Edison Schools.  She’s a Brooklyn convert who runs at a glacial pace and believes that kimchi fried rice with spam topped with a fried egg is the perfect breakfast.


Dave Bryson – he/him/his

Deputy Director

Son of a social worker and a corporate lawyer, Dave grew up in a highly segregated white neighborhood in Boston, MA. The divergent professions of his parents provided him with an early understanding of inequality, as well as his own relative access to power and privilege. Though he didn’t have the language to describe it as a child, this visceral understanding of fairness (and its lack thereof) has driven him ever since seeking out areas of study and employment that provided opportunities to work toward a more just world.

Prior to joining the team at DCSC, Dave helped lead Bedford Stuyvesant Collegiate (part of the Uncommon Schools network in Brooklyn, NY). While he continues to be a proud supporter of his colleagues at Uncommon he always wondered what BSC would look like if the student and family community represented a broader array of racial and socio-economic backgrounds from families across Brooklyn. Dave is inspired by the work of DCSC members because they are answering that question on a daily basis. As Deputy Director at DCSC, Dave appreciates the opportunity to support practitioners realizing the promise of school integration. He also has an extremely specific point of view on what constitutes a high quality sandwich.


Ashley Heard – she/her/hers

Managing Program Director

A Baton Rouge native, Ashley (she, her, hers) grew up moving around the country. She landed in Nashville for college and was shocked by the economic privilege of many of her peers. Thanks to supportive friends, professors who went the extra mile (one loaned her a laptop so she could work on her senior thesis!) and a financial aid officer who more than once found a little extra aid money or another work study job, she made her way. As graduation loomed, she found herself wondering about opportunity, about those who had it, those who lucked into it as she had, and those who were cut off from it. Upon graduation, she joined Teach For America and taught in Washington, DC; she has worked in education ever since.

Ashley returned home to Baton Rouge in 2015. In 2016, Alton Sterling was shot and killed by Baton Rouge police and the response fell along predictable racial lines. Racism, and the segregation that comes with it, is both a defining feature of Baton Rouge’s history as well as its current reality. In 2017, Ashley learned about Diverse Charter Schools Coalition (DCSC) and the work to start intentionally integrated public schools. She was drawn to work that combined her experience in charter school growth with work to integrate schools and, by extension, communities. Ashley now serves as the Managing Director of Program and loves working with UnifiED school launch fellows and explorers. Ashley is an overly lenient dog mom to Annabel, a friend, sister, aunt, and daughter. She is an avid yogi, turned novice runner and bike rider in a covid- 19 world. She can clap one-handed and likes Prince, cooking, wine on the porch, gardening, and Twitter debates.


Seon Britton – he/him/his

Program Manager, Membership Engagement

A product of two first-generation college students of the civil rights era, Seon comes from Detroit, MI. Moving to the suburbs at the age of seven was an early lesson for Seon on how resources are distributed to communities of color vs. white communities. His experiences growing up made him a strong believer of equity in which he chose to work within the education sector teaching 6th grade reading in Arkansas as a Teach For America corps member. After this, he focused on finding great teachers for students by recruiting for TFA and later the NYC Department of Education under NYC Men Teach. Seon currently lives in New York City and when not working on school integration is perfecting his expertise on classic Black 90s sitcoms through Netflix.


Amy Jiravisitcul – she/her/hers

Data & Evaluation Manager

As an educator, Amy consistently sought out institutions that prioritized educational equity. She is a proud daughter of Chinese heritage parents who arrived in the US during the 1980s as refugees from Southeast Asia. Although Amy’s parents hail from Savannakhet, Laos, and Bangkok, Thailand, Amy grew up in a predominantly white suburb of Milford, Connecticut. Amy’s K-12 experiences in a white-centric public school system sparked her passion for disrupting generational legacies of systemic racism, colonialism, and trauma among marginalized communities.

She formerly served on the Board of Directors for Asian American Resource Workshop, supporting programs related to neighborhood-based organizing and fighting anti-Black racism. Amy’s background includes teaching foreign language at the elementary and middle school level, as well as advising underserved students and families in a Boston out-of-school-time academic program. In her free time, she enjoys discussing racial identity development, making pizza dough from scratch, and getting lost in everyone’s Instagram stories.

Veronica Brooks-Uy

Growing up, Veronica Brooks-Uy attended school in rural, southern Virginia. Many of the spaces she navigated were highly segregated, and she often felt people tried to place her into boxes that did not fit. It wasn’t until college when she had the privilege to meet a diversity of people and be exposed to a broad variety of experiences and ideas did she begin to see that those boxes were arbitrary and that she could decide who she wanted to be. As a former teacher and now a mother, Veronica wants to help build a society where her students and her son are allowed to experience the world, determine who they want to be, and live their truths.

Veronica is now the Vice President of Policy at the National Association of Charter School Authorizers NACSA). She started her career as a middle school science teacher and has worked at the Louisiana Department of Education in the authorizing office, served as the Policy Director for the Louisiana Association of Public Charter Schools, and was a Consultant at Public Impact.
