our philosophy

ISE Baseball’s client-centric culture means our players are always our top priority. Having represented numerous Hall of Famers, Most Valuable Players and MLB All-Stars, we know the formula to help our clients maximize their potential during their playing careers and beyond.

At ISE Baseball, we leverage our strong industry relationships to help achieve contractual success for our clients from the MLB Draft through the end of their playing careers. We have more than 35 years combined experience and have negotiated over $1 billion in contracts in the last five years alone.

Our unmatched support off the field includes marketing and endorsement opportunities, public relations and social media strategy, community outreach support and foundation management, and a VIP concierge service.

With several former players as agents, the team at ISE Baseball understands exactly what it takes to be successful in Major League Baseball both on and away from the diamond.
