At The Harry Walker Agency, we work with speakers across an unusually wide range of industries and perspectives. Some are global names who instantly command attention. Others are more specialized voices whose expertise speaks directly to a particular audience or moment.
Our roster includes athletes and entrepreneurs who understand performance under pressure, business leaders shaping modern organizations, and cultural figures whose work has influenced audiences around the world. What connects them is the ability to translate experience into conversations that feel engaging, relevant, and worth hearing.
Whether an event calls for a headline speaker everyone recognizes or a more niche expert with a specific point of view, our team helps match the right voice to the right room.

Few people understand performance under pressure quite like elite athletes. Many of them are also building companies, investing in new ventures, and shaping culture far beyond the field of play. Speakers like ALEX RODRIGUEZ, MAGIC JOHNSON, and MARIA SHARAPOVA have translated championship mindsets into successful business ventures, while icons such as TOM BRADY, SERENA WILLIAMS, and VENUS WILLIAMS reflect on the discipline required to sustain greatness over time.
Audiences also gain perspective from athletes who have redefined their sports and industries, from surf legend KELLY SLATER and skateboarding pioneer TONY HAWK to global champions including LINDSEY VONN, ALLYSON FELIX, MEGAN RAPINOE, and SUE BIRD. Alongside them, personalities like MICHAEL STRAHAN, JOHN CENA, JOHN MCENROE, JIMMIE JOHNSON, and WAYNE GRETZKY bring stories of competition, reinvention, and leadership that resonate well beyond sports.
Venus was absolutely incredible. Everyone is still talking about her fireside chat. She was so gracious with her time and brought such amazing energy to the event.

Today’s organizations are navigating rapid change, and the leaders guiding them bring lessons that extend far beyond the boardroom. Influential executives such as INDRA NOOYI, former CEO of PepsiCo, share firsthand insight into leading global companies through transformation, while entrepreneur EMMA GREDE offers perspective on building modern brands and scaling businesses in competitive markets.
Few leaders have shaped global media and cultural conversation as consistently as ANNA WINTOUR, whose decades of leadership offer a rare perspective on influence, decision-making, and staying ahead of shifting audiences.

"Charles Duhigg is a phenomenal speaker and was able to captivate the Bloomberg audience. His passion for the topic really translates into the audience and everyone picked up on his enthusiasm. I really like the way the Prezi complemented his speaking style. I was a little worried that there might be too much Prezi and not enough Charles but I was wrong—it was the perfect balance."

"The most appropriate way to describe Indra Nooyi, chairman and CEO of PepsiCo, is 'world class leader.' Her sharp strategic mind, tremendous market insight and humanitarian contributions all combine to make her a rare executive among the global corporate giants."

Legendary entertainers STEVE MARTIN and MARTIN SHORT combine storytelling with humor that keeps audiences engaged long after the event ends.
