Jalen Brunson is already an NBA Champion, NBA Finals MVP and King of New York, and now’s he adding a new team, “Thirty Third Management Group”, to his growing empire.

The new venture, which be family owned and operated, was created, per the release, to manage Brunson’s “off-court business and represent clients across professional sports, business and philanthropy.”

“My family has been with me every step of the way, and everything we do is rooted in trust,” said 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.”

The name derives from Brunson’s draft position as he was the 33rd overall pick in the 2018 NBA Draft.

His mom, Sandra, will serve as group President, his sister, Erica, will be the Director of Client Services and Connor Cashaw, Jalen’s good friend and former high school teammate, will be the Director of Business Development; the latter two have been 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.”

Jalen is the firm’s foundational client, but it plans to work with other athletes and “NIL talent, executives, entrepreneurs and charitable foundations on brand development, partnership strategy, business development and philanthropy.”

The group also has a specific focus, led by Erica, on women’s professional sports.

After winning the NBA title, donning the City’s crown, co-hosting “The Roommates Show” podcast with John Hart, making an appearance with Mariska Hargitay in an Emmy promo, being tapped as the host of the September 26th show of “Saturday Night Live” and preparing for the upcoming season, Brunson has lots on his plate.

But it’s all good because his family continues to have his back off the court while he battles to defend the title this season.
