Jalen Brunson and Family Establish Innovative Thirty Third Management Group

On September 16, 2026, Jalen Brunson, the esteemed captain of the New York Knicks and a standout player known for his leadership qualities, alongside his family, formally announced the creation of Thirty Third Management Group. This family-owned brand advisory firm aims to oversee Brunson's off-court businesses while also representing various talents in professional sports, business, and philanthropic sectors.

The name of the firm, Thirty Third Management Group, is significant; it pays homage to the pick number that initiated Brunson's illustrious basketball journey when he was selected 33rd overall in the 2018 NBA Draft. With this firm, Brunson and his family not only establish a brand but also reinforce their values of trust and integrity that have guided their aspirations.

Jalen stated, "My family has been with me every step of the way, and everything we do is rooted in trust. 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." This paradigm reflects the ethos of the company—collaboration and a family-first mentality.

The firm will be spearheaded by Sandra Brunson as President, who has successfully managed Jalen's off-court dealings for the past eight years. Joining her are Erica Brunson, who will serve as Director of Client Services, and Connor Cashaw, the Director of Business Development. Erica and Connor have been integral members of Jalen's support team since 2024 and 2025, respectively, making their contributions to the new venture particularly personal.

In an interview, Erica shared the vision behind the company: "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. We aim to help our clients maximize opportunities across professional sports, business, and philanthropy while being significant partners in their journeys."

While Jalen Brunson will remain the firm's cornerstone client, the overarching ambition is to broaden its reach, advising a dynamic array of clients including athletes, NIL (Name, Image, Likeness) talent, business executives, entrepreneurs, and charitable organizations on brand development, partnership strategies, and business expansions. A distinct area of focus will be on women’s professional sports, a field that the firm’s leaders recognize has not been given enough attention historically. Erica is set to lead this initiative, ensuring that women's professional sports receive due representation and support.

Currently, Thirty Third Management Group is in the process of evaluating potential clients and brand partnerships, signaling the firm’s commitment to a strategic approach that champions not only profit but societal impact as well.
