Board of Directors

Board Chair, Teacher Education Representative (July 2022 – June 2026)

Charity Freeman

My CSTA Story

Charity’s journey as “unofficial brand ambassador for CSTA” began when she received a scholarship to attend the 2019 CSTA Annual Conference. There, she learned about CSTA’s then–brand new Equity Fellowship and went on to join its first cohort! Since then, Charity has written several articles for CSTA’s The Voice, served as the first Equity Strand Lead of the Annual Conference Committee, and led CSTA’s Nominations and Elections Committee. She became chair of the Board of Directors in July 2023. “#iLoveMyCSTA, and I’m passionately committed to our organization’s growth as we support and advocate for our teachers to be seen, heard, and valued.”

My Story

As part of the University of Illinois Urbana-Champaign’s computer science department, Charity Freeman is supporting the launch of two new graduate degree programs in her hometown of Chicago. Tried and true, she’s a diehard Bears fan, staunch supporter of the “Sears Tower,” and a firm believer that ketchup doesn’t belong on hot dogs. Her determined spirit carries into her work in CS education throughout the state of Illinois, where she helps lead the newly formed ECEP Illinois team. As a governor-appointed member of the Illinois P–20 Council, she co-chairs a project-based working group on scaling K–12 CS education. Charity is also the lead instructor of the Teaching Methods in Computer Science endorsement course for in-service teachers at UIUC’s College of Education.

In her spare time… That’s funny. Charity’s rarely-enjoyed hobbies include watching football, playing tennis, and enjoying dinner with her family. Meanwhile, she’ll continue focusing on building and sustaining K–20 CS education ecosystems that systematically identify and address disparities in opportunities, outcomes, and representation in computing education.

Andrea Wilson Vazquez

My CSTA Story

I became involved with CSTA as a teacher who started volunteering with a local CS-focused nonprofit on the weekends. I was passionate about the need to bring CS into the K-12 school day so that all learners could experience the power of creating new things with technology and was excited to find others with similar vision! I soon joined my chapter’s leadership team and then got involved with national CSTA projects, including as an Equity Fellow (2022-23), CSforELs program facilitator, and most recently joined a team helping to update the CSTA coaching toolkit.

Carla Neely

My CSTA Story

Since joining CSTA in 2018, Carla has come to appreciate and respect how much scope computer science offers for students to add their own individuality and creativity. Carla believes that students need to be exposed to computer science beginning at the early grades, just as they require early exposure to learn a second language. Computer science needs to be equal and equitable for all students, and Carla considers herself an advocate for girls in computer science, especially girls of color and girls from other underrepresented communities.

My Story

Carla Neely is a 5th–8th–grade science and computer science teacher. She has found a way to integrate the two subjects together, resulting in memorable learning experiences for all of her students, and she now coaches teachers at her school to integrate computer science into core subjects.

In addition to his teaching responsibilities, Delmar is chair of the math department, ESSAC chairperson, union steward, and head coach of boys’ varsity basketball.

As Delmar began working on his doctorate degree in 2013, he came to the realization that there weren’t enough minorities in computer science. He created an AP CSP course at his school and began by recruiting his ninth graders, none had ever dreamed of taking a computer science course, much less an AP course. Over the years, this course has become a student favorite, and in 2021 he started the school’s first Computer Science Honor Society. As a veteran teacher, Delmar continues to push CS forward by utilizing his CS Honor Society to broaden CS participation and by introducing students to CS during Computer Science Week. Delmar believes that computer science is not just for a select few; it is for everyone. It has the power to transcend boundaries, break barriers, and unlock the unlimited potential within each and every student. As teachers of the 21st century, we have a commitment to ensure that we are effectively preparing our students to be future leaders.

Kimberly Hermans

My CSTA Story

Being the only computer science teacher at her school, Kimberly was eager to connect to other computer science teachers, even if that meant driving over an hour on a Saturday morning to attend the closest CSTA meeting back in 2012. In 2018, Kimberly was able to attend her first CSTA Conference, where she presented on Google Firebase. Kimberly was inspired by the community of educators at the conference, and soon after joined a newly chartered local CSTA chapter closer to her home. She has since been involved with CSTA, presenting at conferences and serving as a representative to CSTA GLA.

My Story

Kimberly Hermans has taught AP Computer Science A for 14 years and AP Computer Science Principles since the pilot program’s inception in 2013. She also has 7 years of experience lecturing computer science at California State University, Fullerton, and the University of California, Irvine.

CSTA Board Treasurer (July 2024 - June 2026)

Yolanda Lozano

My CSTA Story

I joined CSTA in 2018 when I began teaching in New Mexico. As the only CS teacher at my high school, I was thrilled to connect with like-minded educators statewide and nationally. Gradually, I became more involved, leveraging my programming experience to contribute to the group. This led to my role as president of the New Mexico chapter, and eventually, I was elected to the board.

My Story

Yolanda’s interest in computer science began as a TA for a technology course at the University of Michigan. She earned an MS in data modeling and Management from Carnegie Mellon, followed by roles at Rice University and the Board of Governors of the Federal Reserve. She later embraced an entrepreneurial challenge with a Harvard Business School tech/finance start-up, leading to its successful acquisition. After a career in software, retiring from Citrix Systems in corporate strategy, she now manages funding from NSF, USDA, and major tech companies to advance equitable CS education. Yolanda serves on the IEEE Quantum Education Committee, is a board member of Elevate Quantum Workforce Collaborative (EQWC), state representative for AI4K12, treasurer of the Computer Science Teachers Association, and teaches computer science at Gogebic Community College.
