Our Team
Catina Voellinger
Executive Director
She/her
Born into a biracial family in Texas, Catina's unique perspective greatly informs her role at Ground Game Texas. Raised by a mother who experienced extreme poverty in Central Texas and a father from a working-class family in North East Texas, Catina directly experienced economic and racial inequality. The insight she gained from her upbringing spurred a career dedicated to challenging injustices, advocating for workers' rights, and promoting racial equity.
Prior to joining Ground Game Texas, Catina co-founded the first worker-owned political consultancy cooperative in the U.S., advocating for campaign workers and replacing a disposable culture with one that values every team member. Catina utilizes her versatile expertise in campaign management, compliance, fundraising, design, and communications to actively confront and deconstruct systems that suppress underrepresented communities. She first came on to the team at Ground Game in early 2022, and achieved an array of essential accomplishments, including building our institutional fundraising program, overhauling our communications materials, taking charge of our largest ballot measure campaigns, and generally building a focused, constructive, and collaborative culture.
Catina’s deep dedication, paired with her strategic approach, make her a vibrant force at Ground Game Texas and an inspiring leader in our shared goal of building a more equitable and just world.
