Dave Parro was born April 30, 1957 in Saskatoon, Saskatchewan. The 2nd choice, 34th overall selection of the Boston Bruins in the 1977 NHL Entry Draft, Parro is a graduate of the Saskatchewan Junior Hockey League's Saskatoon Olympics and of the Western Canadian Junior Hockey League's Saskatoon Blades.
The Saskatoon, Saskatchewan spent two seasons between the pipes with the Blades earning WCJHL Second Team All-Star honors in 1977 before joining the American Hockey League's Rochester Americans in 1977-78. In only his first season as a professional, Parro strong play continued as he was named an AHL Second Team All-Star.
In 1978-79, Parro spent the majority of the season in Rochester while playing in a handful of games with the International Hockey League's Grand Rapids Owls before being claimed in by the Quebec Nordiques in the 1979 Expansion Draft.
Even though he had been claimed by Quebec, Parro was on the move yet again only two days later after the Nordiques traded him to the Washington Capitals. Upon being acquired by the Caps, Parro spent the 1979-80 season as a member of the AHL's Hershey Bears before making his NHL debut the following year.
Parro went on to split his 1980-81 season with the Caps and the AHL's Bears before earning a full time roster spot the following year. During the 1981-82 season, Parro played in 52 games with Washington before returning to Hershey the following year. Over the next two seasons, Parro played in only seven games with the Caps while spending the majority of his seasons in Hershey.
In 1984-85, Parro joined the IHL's Salt Lake Golden Eagles and over the next two years had stops in the "I" with Flint, Fort Wayne and Indianapolis.
