    Read More

    • Michele first joined GDC close to 25 years ago, in the earliest days of the agency after working on the national PR team for Builders Square for Anderson Advertising. She used her experience in public relations and broadcast journalism to help clients like Citibank and H-E-B create internal communication campaigns to engage their teams across the country. Michele quickly moved up the ranks in GDC and was named group account director for all agency retail and CPG clients, including the Shopper Marketing team at Procter & Gamble with a focus on 300+ H-E-B stores in Texas and 3,500 Albertson’s stores across the US.

      While at GDC, and using insights from her CPG and retail experience, she became a founding partner in CartStart™, an in-aisle sales application for retail employees. Funded in part by Procter & Gamble, Unilever, Revlon, and L’Oreal and others, the sales app was leveraged by over 80 H-E-B beauty departments in Texas to help the store’s Beauty Advisors position the right hair, skin, or cosmetic brand based on customer’s needs.

      After leaving GDC in 2015, Michele focused on her two passions—children’s mental health and education and worked in leadership roles for Child Guidance Center and KIPP Texas Public Schools. Michele accepted the opportunity to re-join GDC as the Chief Operating Officer in 2020.

  • Tom Lewis

    Controller

    bio

    If something’s out of order, Tom notices. He’s “a little OCD” and likes to keep his pictures hanging straight, his receipts in a shoebox, and his dog neatly brushed.

    Read More

    • The trait obviously comes in handy in leading our accounting team at GDC. And the best part is, he streamlines the paperwork process to keep the message in the numbers clear and concise.

      Though he was born with an eye for the details, Tom has further developed the skill with a lengthy accounting résumé. When he came to GDC in 2009, he brought with him extensive experience from the Interpublic Group family of agencies. And he began his career in public accounting with an emphasis in retail at PriceWaterhouseCoopers in North Carolina.

      Tom is married with two daughters and a mutt. The family garage remains a mess, but he’s working on it.
