Tammy Tibbetts pairs bold vision with disciplined execution to create lasting impact.

Tammy Tibbetts is a nonprofit founder, CEO, and advisor whose career has elevated girls through education, leadership, and systems change. She is pursuing her next role at a foundation — using her experience as a grantee and champion of grassroots organizations to deepen impact through more inclusive, effective philanthropy.

As the founding CEO of She’s the First for 16 years, Tammy scaled her idea for an advocacy campaign into a robust international organization, registered in the U.S. and Kenya, that ultimately reached over 1 million girls and 800+ community organizations. She mobilized $18 million in funding, developed national partnerships with major brands like Estée Lauder, Anthropologie, and Barbie; nurtured relationships with diverse stakeholders, from grassroots leaders and girls to foundations, media, and celebrities; and fueled coalition-building efforts among NGOs and funders.

In 2025, Tammy led She's the First through a strategic merger, setting an uncommon example in the sector, one driven by vision and values over ego. During the 2026 integration year, she serves as Chief Advisor to Girl Rising — shaping the mission, strategy, and culture of the merged entity.

Entrepreneurial at heart, Tammy has been the first person to fill every job she’s ever held. Before her nonprofit career, she was the first-ever social media editor of Seventeen magazine and led innovative girl-centered projects for Hearst Digital Media.

Tammy authored Impact: A Step-by-Step Plan to Create the World You Want to Live In (Hachette PublicAffairs, 2020 hardcover and 2023 paperback), reviewed by presidential inaugural poet Amanda Gorman as “your guide for how to make change in a world that desperately needs it.”

Tammy is a Diane von Furstenberg People’s Voice Award and Women in Innovation Award winner, a three-time TEDx speaker, and a first-generation college graduate who later became a trustee of her alma mater, The College of New Jersey. After being an International Women’s Forum 2024-2025 Fellow, she joined the Women’s Forum of New York, where she serves on the Education Fund Committee.

When she’s not in Brooklyn with her husband, son, and mini poodle, her favorite place to be is Edinburgh, Scotland.

After my one-year term as Chief Advisor to Girl Rising, I want to bring everything I've learned on the nonprofit side into a career in philanthropy. This might be an Executive Director role at a family foundation or a Program Officer role at a larger foundation.

By leading an ‘intermediary’ organization for nearly two decades, I was both a grantee myself and a grantmaker to grassroots organizations. This dual experience is rare and shaped my passion for philanthropy, along with skills that directly translate:

  • Empathy with grantees and fluency in working across wide cultural and contextual differences. I know what "beyond the check" support looks like when it works (and what gets in the way).

  • Excellence in building diverse networks of grantee partners and funders. I led co-funding models involving multiple donors, fostering knowledge sharing among funders and grantees.

  • Power-balancing management style. I led a multi-cultural staff across time zones and grew a Board of Directors from start-up to maturity.

Please let me know if you see an opportunity for 2027!

CHAMPION OF STRATEGIC MERGERS & PARTNERSHIPS

Having led She's the First through a strategic merger in 2025, I guide teams through change with care and clarity. I facilitate power-balancing within new structures, inspiring healthy co-creation of culture and norms. I navigate the emotional and logistical complexity of a merger with quick thinking, deep attention to detail, and contagious joy — and bring that same energy to every collaboration I lead. I am a skilled networker who knows how to bring the right people together for a mutual win.
