Tournament of Roses Executive Vice President Jeffrey Throop said DiSano died of cancer at his home in San Juan Capistrano.
"Gary DiSano was an enthusiastic and fun-loving individual. He was passionate about the Parade and Game and never let any setbacks inhibit his dedication to the organization. He will be greatly missed. The 2010 Rose Parade and Rose Bowl Game will be held on January 1 in his honor," Throop said in a statement.
DiSano had volunteered at the Pasadena Tournament of Roses Association since 1972.
He was born in Los Angeles and attended La Salle High School in Pasadena. He earned a degree in marketing from the University of Southern California and later attended Harvard Business School.
He went on to become the Director of Heavy Duty Purchasing for Century Wheel and Rim in Montebello and RGGL Corporation in Newport Beach.
DiSano is survived by his wife, Sabina, and three children.
Funeral services will be private.
The family requests that in lieu of flowers, donations be sent to the Hoag Cancer Center, the USC Norris Comprehensive Cancer Center or the Tournament of Roses Foundation.
