Empowering North Texas Nonprofits.

The Big Give is an one-day hackathon, where digital professionals in North Texas volunteer their time and skillsets to transform the web presences of local, nonprofit organizations.

The Big Give 2019 will take place on Saturday, October 5, at Toyota Connected in Plano, Texas.


Our Mission

We transform local, nonprofit organizations serving our community through the mobilization of digital professionals as technological resources for our one-day hackathon events.

In short, we gather Fortune 500 tech rock stars, who volunteer their time to build or enhance websites, software and applications for nonprofits.

Bringing together need and ability, we can directly improve our common future.

Get Involved

There are multiple opportunities for those interested in volunteering! We welcome all to spread the word, donate to The Big Give, or volunteer your administrative muscle on the day-of at our hackathons.



Are you interested in becoming one of the nonprofits we transform? 

Learn more about how we can help meet your organization's needs.



We're looking for designers, developers, analysts, product and project managers, photographers, videographers, copywriters, and social media, SEO and information security experts, as well as volunteers for day-of efforts.



Your tax-deductible donation helps us provide resources to local nonprofits. 

As an all-volunteer nonprofit organization, we can't do it without you.


Our Partners

The Big Give would not be able to provide these services to nonprofits without the generous support of our community partners, corporate sponsors and in-kind sponsors.

The Marzban Family




Our Team

Our Board of Directors has a wealth of experience and knowledge in the nonprofit sector and the digital space, coupled with a drive to give back.



Bill builds internal creative and user experience teams that help companies to build better products faster. Having led multiple international UX teams for many years, Bill most recently built out an Enterprise UX Team at RealPage in Dallas, TX. He is currently at Texas Instruments in Richardson, TX.

Building and operating an Enterprise UX Team across a 5,000+ person enterprise is exactly the type of challenge that energizes him. Building a team of natural collaborators who know when to take a step back and allow their teammates to shine and to continue to be life-long learners is what has brought us this amazing level of success and what will continue to allow us to deliver User Experience capabilities at scale across the entire enterprise.

Bill is also on the Board of Experience Driven in Dallas.



Catherine discovered her passion for helping people and organizations flourish by managing learning programs in organizations. Her work with nonprofits has focused on helping to grow professional communities through a variety of channels, including technological tools and conferences, which dovetails nicely into the hackathon world.

Catherine holds a Bachelor of Science in Business Administration from UT Dallas. 

She is extremely fond of all dogs, but mostly the extremely shaggy ones. Much to the chagrin of her dieting husband, she is a phenomenal home baker, crafting the most delicious and gluten-filled desserts one could ever dream of.



Geoff has been crafting interactive experiences for small businesses, nonprofits and tiny startups to giant corporations since 1997. While working at nonprofits, he noted the lack of technological resources and vowed to fill this need.

After graduating with a Master of Fine Arts from ArtCenter College of Design, Geoff has continued to serve the nonprofit community, but in a volunteer capacity––both physical and digital––and felt compelled to do more for the Dallas community.

Ask him about Texas BBQ, he and his wife’s fixer-upper or the Greater Good initiative at Armor.



Keisha is the founder of Brass Tacks Collective and BT Foundry, a hybrid creative experience agency in Dallas that offers a one year, paid apprenticeship to creatives entering the industry.

In conjunction with her work for the agency, Keisha is also deeply involved in the nonprofit community. She sits on the board of Union Coffee and over the course of the last 8 years, she and BTC have done creative work for Union, Café Momentum, the Commit Partnership, MPACT for Mankind, TeachDFW, For Oak Cliff, and many others.

Her biggest passions include social, racial, and gender equity, experiencing all the food, and being the one person living that knows more about The Golden Girls than Betty White.


Laura Martinez

Laura has been designing things in the hopes of making people’s lives better for over 15 years for big companies, small start ups, non profits and many people and businesses that fit somewhere in between. 

She is passionate about helping people realize their full potential and unlock the amazing things inside of them - especially those less fortunate who may not be aware of their abilities because they have never had exposure to what they could truly achieve. She continually advocates for the power of design beyond web screens and app concepts. 

Laura currently leads the product and marketing design teams as the Head of Design for Auto Refinance at Capital One. She lives in Grapevine with her husband Frank, her daughter Celia, and her two rescue mutts, Lola and Chuy.   



With over twenty years of experience and specialized training, Lisa Rattner is a licensed Clinical Social Worker serving women, families and couples. Lisa’s passion is helping women (and their relationships) break through strongholds and navigate through life’s challenges. Her goal is to help her clients find peace and joy while experiencing the fullness of their identities.

Lisa has a keen sensitivity toward those who are suffering with grief and loss associated with trauma. She was part of a team of clinicians who provided counseling to widows and families in a New Jersey community who lost loved ones during the September 11th terrorist attack - one of the most traumatic periods this country has ever experienced.



Mark has a deep knowledge of product management in the tech space, having worked two decades at Microsoft, Active Network, GameStop, RealPage and Armor. He is currently a Senior Product Owner at Toyota Connected. 

As a former Staff Sergeant of the United States Air Force, Mark is active in veterans' organizations, such as Team RWB, as well as other nonprofit organizations, such as the Active Joe endurance races.  He is also active in the product management meetup community and Toastmasters.

He enjoys running with his family and friends and is also passionate about soccer. He and his wife of 28 years enjoy date nights at the FC Dallas games.
