## Brunson launches family firm
Jalen Brunson announced Thirty Third Management Group, a brand advisory firm run by his mother Sandra as President and sister Erica as Director of Client Services.

> My family has been with me every step of the way, and everything we do is rooted in trust.
## The name honors his draft story
Thirty Third references Brunson's 33rd overall pick in the 2018 NBA draft, a humble beginning before his rise to stardom.
## Family already managed his career
Sandra has guided Jalen's off-court work since his NBA start, while Erica and friend Connor Cashaw managed his marketing as CAA employees before the transition.
## Sponsorships and media deals
Brunson has built a lucrative portfolio including Nike, AT&T, BodyArmor, DoorDash and Dunkin' Donuts, plus his podcast The Roommates Show with Josh Hart.
## SNL host and cultural moment
Brunson will host Saturday Night Live on September 26, becoming the first Knick and just the fifth NBA player ever to host the show.
## Top athlete in New York City
At 30, Brunson's squeaky clean image and success on and off the court make him the most recognized athlete in the city, and the first client of his family's new venture.
## Key takeaway

Brunson is consolidating his growing media and sponsorship empire under family ownership, moving his team from CAA to a new independent firm.
