Being a part of the SIG sports agency is like being a part of another family. They make you feel like a family member versus a client with the true personal attention and the amount of time and effort they put into helping develop your career.

Candace Parker
Forward, Chicago Sky

Being with SIG has given me the opportunity to complement my WNBA career with playing overseas. Trusting SIG’s worldwide knowledge of the ins and out of this business has allowed me to maximize my earning potential. Trusting your agent is key and the quality I most appreciate in Boris is his honesty!
