GCISD BOARD OF TRUSTEES ELECTION – 2026
A DEEPER DIVE
Author: Eldon Thomas
Published April 21
The Grapevine-Colleyville Independent School District will hold elections for three trustee positions on May 2, 2026. In each race, experienced incumbents who have served since 2023 face challengers.
These are not minor races. They will shape how GCISD handles taxes, enrollment decline, school closures, and long-term planning. The choice in each race comes down to a simple question: Do we continue with proven, steady leadership that has delivered strong results, or risk a change in direction?
PLACE 5
A.J. Pontillo (Incumbent) vs. Matthew White
A.J. Pontillo offers proven continuity, deep local roots, and unwavering commitment. A proud GCISD graduate of Grapevine High School and a longtime Grapevine resident for over 30 years, he brings valuable expertise from a distinguished career in federal law enforcement. Now completing his first full term as trustee (elected in 2023), A.J. has demonstrated steady, hands-on leadership and a consistent focus on safety, academic excellence, and responsible financial oversight. He has been endorsed by the Grapevine Professional Firefighters Association, which speaks directly to his focus and expertise on safety.
During his time on the board, GCISD has maintained strong academic rankings and a competitive reputation across the DFW region and Texas. He has been directly involved in key financial decisions, including support for the 2024 VATRE that strengthened classroom funding while helping keep the overall tax rate low and manageable for families. His profile is one of reliability: local, consistent, and deeply invested in the long-term success of the district he knows so well.
Matthew White brings a varied professional background, including time as a teacher/coach, followed by law school and a stint as an attorney, then a campus administrator in GCISD (Assistant Principal at Grapevine Middle School and Associate Principal at Collegiate Academy), and has since started another stint as an attorney. His career reflects multiple transitions across different roles and professions.
This raises a legitimate question for voters: If Matthew White changes careers relatively often, how long will he truly commit to serving as a trustee? School board service requires sustained dedication through challenging issues like enrollment declines, facility consolidations, and tight budgets — not short-term involvement. In contrast, A.J. Pontillo has shown consistent, long-term investment in the Grapevine-Colleyville community and its schools.
Matthew appears to be a one-issue candidate, as evidenced by his comments at a school board meeting where he stated he looked forward to being part of a board that would re-open Dove Elementary and install a large bronze plaque outside to “shame” all of the trustees that voted to close it.
Matthew has, on multiple occasions, indicated support for a potential tax increase. This first surfaced in a podcast and more recently in a Facebook exchange with a local resident. When challenged, he points out that he cannot raise taxes on his own, which is true. However, a board can vote to place a tax increase on the ballot for voter approval. The concern is his willingness to pursue a tax increase while clear efficiencies still exist within GCISD that could improve the budget without asking taxpayers for more.
This race is a clear contrast between steady, proven local leadership with a track record of continuity and results versus a candidate whose professional path suggests less stability and points to a short-term focus.
PLACE 6
Dianna Sager (Incumbent) vs. Lindsey Sheguit
Dianna Sager brings outstanding depth, continuity, and insider expertise to the board. With 33 years of classroom experience — including more than 20 years inside GCISD as a dedicated teacher and highly successful coach — she has built winning programs, led teams, and understands every level of district operations from the classroom to the boardroom.
Now in her third year as trustee, Dianna has contributed directly to maintaining GCISD’s strong academic rankings and its reputation as the #1 Best Place to Teach in the entire DFW area (2026 Niche rankings). She has also been part of prudent financial decisions that balanced classroom needs with responsible tax rate management. Her long-term, continuous involvement as a parent, teacher, coach, and trustee demonstrates unwavering commitment and a deep investment in the district’s success.
Lindsey Sheguit is a GCISD graduate and longtime Grapevine resident who moved her family back to the district so her children could attend GCISD schools. She is married to a teacher and currently serves as Chief of the Misdemeanor Trial Division in the Denton County District Attorney’s Office.
While these qualities are valuable, her professional experience is primarily in prosecution rather than education administration, budgeting, policy development, or long-range district planning. Translating courtroom and legal skills to the complex governance responsibilities of a school board trustee remains an open question.
Her campaign logo prominently features a silhouette of a young girl positioned behind the first three letters of her last name “SHE.” Some voters are asking: Is she giving us her pronouns? This imagery may remind many in the community of the CRT and DEI initiatives that GCISD worked hard to remove from the district just a few years ago. For those voters, this becomes an important part of the evaluation when considering long-term leadership and direction for our schools.
This race presents a clear contrast between deep, proven educational experience and decades of direct, continuous involvement inside GCISD versus a candidate with limited direct experience in school district governance and whose campaign choices raise questions about priorities and alignment with recent district reforms.
PLACE 7
Mary Humphrey (Incumbent) vs. Darrell Brown
Mary Humphrey represents deep-rooted commitment, continuity, and a genuine investment in GCISD. Her background is firmly anchored in education and long-term community involvement within the Grapevine-Colleyville area. She has supported the district in multiple roles over many years — as a parent, volunteer, and advocate — before stepping up to serve as trustee.
Now in her third year on the board (and serving as board vice president), Mary has contributed directly to decisions that have helped sustain GCISD’s strong academic performance, maintain its competitive reputation in the region, and navigate financial challenges with care and responsibility. Her steady, district-focused approach reflects reliability, established local knowledge, and a consistent dedication to what is best for GCISD students, teachers, and families.
Darrell Brown has 30 years of experience in public education. He has worked as a teacher and administrator across multiple North Texas districts before eventually serving as an elementary principal before retiring.
His career involved frequent movement between several districts rather than deep, sustained commitment to a single community like GCISD. Voters will have to weigh whether this less localized experience provides the long-term stability and community-specific understanding needed for effective trustee service — especially during challenging times involving enrollment decline, facility decisions, and budget pressures.
Darrell Brown appears to be driven largely by the Bransford closure. His daughter teaches there. His grandchildren attend there. That connection matters. His own campaign page says that just a year ago, he had no intention of running. He claims he decided to run due declining enrollment, financial challenges, and school closures. But those first two issues were already present a year ago. The only real change since then is the decision to consolidate schools. Is this campaign about the district as a whole, or about one specific outcome?
This race offers a clear contrast between strong, established roots and continuous dedication to the GCISD community versus a candidate with wide-ranging experience across multiple districts but without the same depth of long-term involvement in our specific schools and families.
THE BIGGER PICTURE
All three races follow the same clear pattern: Incumbents who have proven themselves through hands-on service, deep knowledge of GCISD, and responsible decision-making during difficult times. Challengers who bring different, and sometimes unrelated backgrounds and raise legitimate questions about long-term commitment, stability, and alignment with the direction voters have chosen for the district in recent years.
The challenges facing GCISD are significant — declining enrollment, tight state funding, necessary facility adjustments, and careful tax policy. Under the leadership of A.J. Pontillo, Dianna Sager, and Mary Humphrey, the current board has maintained strong academic rankings, earned the #1 ranking as the best place to teach in the DFW area, kept the overall tax rate among the lowest in the region, and successfully passed the 2024 VATRE to strengthen classroom funding without increasing the total tax burden on families.
Experience, continuity, and steady governance have served GCISD well. Introducing new voices with less district-specific experience and uncertain long-term focus carries real risk at a time when stability matters most.
FINAL THOUGHT
This election is not about personalities. It is about direction and proven results.
A.J. Pontillo, Dianna Sager, and Mary Humphrey have demonstrated the steady leadership, deep local knowledge, and responsible stewardship that GCISD needs right now. They have helped keep our district strong academically, fiscally sound, and focused on what matters most — our students and teachers.
Voters have a clear choice: Continue with experienced, reliable incumbents who have already shown they can navigate challenges successfully or turn to challengers whose backgrounds raise legitimate questions about commitment, plans for increased taxes, stability, and alignment with the progress we have made.
For those who value continuity, fiscal responsibility, and long-term dedication to GCISD, the strongest choice in each race is to re-elect the incumbents:
✅ A.J. Pontillo – Place 5
✅ Dianna Sager – Place 6
✅ Mary Humphrey – Place 7
Steady, proven hands at the helm have served our district well — and deserve strong support on May 2, 2026.
