Family-owned brand advisory firm will manage Brunson’s off-court business and represent athletes, NIL talent, executives, entrepreneurs and charitable foundations

NEW YORK, Sept. 16, 2026 /PRNewswire/ — New York Knicks captain, 2026 NBA Champion and Finals MVP Jalen Brunson and his family today announced the launch of Thirty Third Management Group, a family-owned brand advisory firm that will manage his off-court business and represent clients across professional sports, business and philanthropy.

The firm takes its name from the pick that started Brunson’s career. Selected 33rd overall in the 2018 NBA Draft, he has built a reputation defined as much by character and leadership as by what he has done on the court.

“My family has been with me every step of the way, and everything we do is rooted in trust,” said Jalen Brunson. “Thirty Third gives us the chance to take ownership of my off-court business, to build something that reflects who we are, and to do it together.”

Sandra Brunson, who has been managing Jalen’s off-court business for eight years, will serve as President. Erica Brunson will serve as Director of Client Services and Connor Cashaw as Director of Business Development. Erica and Connor have been a part of Jalen’s team since 2024 and 2025, respectively.

“This firm was born from a belief that the most powerful brands are built on trust, purpose, and genuine human connection. As a family, we’ve had the privilege of supporting Jalen’s growth beyond basketball, and that experience inspired us to create an advisory platform that helps others do the same,” said Erica. “We are committed to helping our clients maximize opportunities, whether in professional sports, business, or philanthropy, and want to be a strategic partner that champions both success and significance.”

While Brunson serves as the firm’s foundational client, Thirty Third was built with a wider goal in mind: advising athletes, NIL talent, executives, entrepreneurs and charitable foundations on brand development, partnership strategy, business development and philanthropy.

A priority from the outset will be women’s professional sports, a category the firm’s leadership views as historically underserved. Erica will lead that effort.

Thirty Third Management Group is currently evaluating new client relationships and brand partnerships.
