OUR Team




Marty is responsible for contract negotiation, player recruitment and talent evaluation, as well as providing the personal attention that helps each client reach his full potential as a professional athlete both during and after their career in professional sports. Marty has been involved with football, contract negotiation, and player recruitment for over 16 years.

As a lifelong native of Norristown, PA, Marty began his affiliation with sports by playing baseball and basketball in the Police Athletic League (PAL). He continued playing through Junior High, High School (Norristown HS), and college (Penn State University in State College, PA).

After graduating from Penn State where he earned a degree in Marketing (B.S. Business Administration), Marty went on to work with one of the largest independently owned sports representation firms in the country where he became heavily involved in player recruitment and talent evaluation. He was instrumental in several marketing and business development initiatives there while also sharpening his knowledge of professional sports, contract negotiation, and recruitment skills.

In 2005, Marty left to form his own agency dedicated to providing the personal attention that is not always available from a larger firm. Over the last 16 years Marty has built an extensive list of contact relationships in the professional sports world, and has successfully negotiated contracts for hundreds of players. He has been involved with many players over this career and uses his experience to work with each client individually so they can realize their full potential as professional athletes.
