Our Purpose

At SLG Sports & Entertainment, we strive to fiercely protect our clients, their careers and their earnings.

We are available. We are honest. We believe in what we do. Our purpose is to provide our clients with a comprehensive understanding of the business side of the NFL, along with realistic expectations for what they can expect in their careers. From the first overall pick to the last man to make a roster, our experience has given us the knowledge, network, and insight into every aspect of our clients’ professional football careers.

Consistency

Any agent can have a good day, week, or year, but 32 years and counting simply cannot be matched.
