Glenn Patrick was born April 26, 1950 in New York, NY. A graduate of the Western Collegiate Hockey Association's University of Denver Pioneers, Patrick joined the Central Hockey League's Kansas City Blues for three games following his second and final year at Denver.
The son of Lynn and brother of Craig Patrick, Glenn signed as a free agent with the St. Louis Blues in March of 1970 before splitting his 1971-72 season with the International Hockey League's Columbus Seals and Western Hockey League's Denver Spurs.
In February of 1972, the Miami-Philadelphia franchise of the World Hockey Association selected Patrick in the WHA General Player Draft before he returned to the Spurs line up for the 1972-73 season.
The New York, NY native made his NHL debut with the Blues during the 1973-74 season. Although he spent the majority of the season with Denver, Patrick played in his first NHL game with the Blues before being dealt to the California Golden Seals during the off-season.
Patrick went on to spend the better part of the 1974-75 season with the CHL's Salt Lake Golden Eagles while only suiting up for two games with the Golden Seals before joining the Golden Eagles for the entire 1975-76 season.
In the summer of 1976, Patrick transferred to Cleveland after the California franchise relocated. The 1976-77 season marked a career high in games played for Patrick, as he suited up for 35 games, scoring his first two NHL goals before signing as a free agent with the WHA's Edmonton Oilers after being released midway through the season by the Crusaders.
During the 1978-79 season, Patrick saw action in the American Hockey League with the Hampton Gulls and the Hershey Bears while also suiting up for the U.S. National team competing in the 1979 World Championships.
Patrick joined the North East Hockey League's Hampton Aces in 1979-80 before retiring from the game following the season only to return in 1982-83 as coach of the IHL's Peoria Prancers. After two seasons as coach in Peoria, Patrick stepped away from the game once again returning to the game in 1992-93 as the assistant coach for the East Coast Hockey League's Hampton Roads Admirals.
In 1994, Patrick returned for a third time to the game as a member of the Pittsburgh Penguins organization whose general manager was Patrick's brother Craig. Patrick stayed on with the Penguins until 1997, then went on to join the AHL's Syracuse Crunch as an assistant coach before returning for a second time to the Penguins organization, this time its AHL affiliate coach in Wilkes-Barre Scranton.
