Charles M. "Chuck" Greenberg (born in Englewood, New Jersey, 1961) is an American sports attorney, chairman and founder of the Greenberg Sports Group, and owner of three minor league baseball teams. Greenberg was managing partner of Rangers Baseball Express, LLC, which on August 5, 2010, won court approval to purchase the Texas Rangers, a Major League Baseball team, from Tom Hicks and Hicks Sports Group. Greenberg served as Managing Partner and CEO of the Rangers. The Dallas Observer said in April 2010 that Greenberg “has the money and moxie to lead the Texas Rangers back to relevancy and into the playoffs.”
On March 11, 2011, Greenberg announced that he was stepping down as Managing Partner and Chief Executive Officer of the Texas Rangers and that he would be selling his interest in the Rangers and will no longer be associated with the franchise.
Greenberg was born to a Jewish family, in Englewood, New Jersey, but his family moved to Pittsburgh before his first birthday. He is one of three sons of David and Barbara Greenberg. He graduated from Upper St. Clair High School in Pittsburgh in 1978 and went on to enroll at Tufts University in Massachusetts.
While at Tufts, Greenberg majored in political science and graduated summa cum laude with a bachelor's degree in 1982. From there he went onto the University of Michigan Law School, where he received his juris doctor in 1985.
After law school, Greenberg began his law career in his hometown of Pittsburgh, as an associate and then partner at Cohen & Grigsby P.C., where he practiced for 13 years. In 1998, he joined Pepper Hamilton LLP as a corporate and sports attorney and a partner in the Pennsylvania-based law firm. While at Pepper Hamilton, Greenberg headed the firm's sports practice and was a member of its Executive Committee from 2002 to 2008.
Among his most prominent work as a sports industry attorney, Greenberg was instrumental in a deal that landed NHL Hall of Famer, Mario Lemieux, ownership of the then-bankrupt Pittsburgh Penguins hockey team in 1999. The deal is credited with saving the franchise for the city and Western Pennsylvania. In 2007, Greenberg again represented Lemieux and the Penguins in successful negotiations with the state, the City of Pittsburgh and Allegheny County which resulted in a deal to build the brand-new, state-of-the-art Consol Energy Center in downtown Pittsburgh and secured the future of the Penguins in Pittsburgh for another 30 years.
