Galen's most notable donations were to build USC's on-campus basketball and volleyball arena: the 10,258 seat Galen Center, which opened on October 12, 2006. USC had planned to build a substantial on-campus basketball arena for over 100 years. As a student, Galen attended USC Men's Basketball games in the Shrine Auditorium and Pan-Pacific Auditorium and felt that the team required a better facility. After USC football quarterback Carson Palmer won the 2002 Heisman Trophy, Galen donated $10 million to move the development process forward. On August 28, 2003, Galen donated an additional $25 million to the project to have the building named after himself and his wife. The Galens upped their donation an additional $15 million to make sure that a connected practice facility would also bear their name, bringing the total donation to $50 million.
