Galusha is the sister of Canadian curler Kevin Koe, who skips a team out of Alberta, and twin sister of curler Jamie Koe, who skips a team out of the Northwest Territories. She works for the Government of the Northwest Territories as a Finance Officer for the Department of Justice. She was born in Yellowknife, November 3, 1977. She is married to Scott Galusha, and they have a daughter together, Sydney Galusha.
Galusha's first national experience was at the 1992 Canadian Junior Curling Championships. She was the fifth player for Janet Sian. The team would finish in eleventh place with a 2-9 record.
The 2001 Scott Tournament of Hearts, was the first time Galusha would represent the Territories as a skip. Her team finished last place, with a round robin record of 2-9. Galusha would return a year later to the 2002 Scott Tournament of Hearts, as a fifth player for Monigue Gagnier. The team finished round robin with a 4-7 record.
It wasn't until 2005 that Galusha would return to the Scotties, this would be the start of five consecutive years representing the Territories. At the 2005 Scott Tournament of Hearts Galusha would make a slight change, throwing third rocks while skipping the game. The 4th rock thrower was Monigue Gagnier, and the team would finish round robin with a 4-7 record.
Galusha and her team found early success during the 2011/2012 season. During the World Curling Tour, they defeated defending Canadian champion Amber Holland, and Olympic Silver Medalist Cheryl Bernard, and for the first time qualified for the playoffs during a tour event. They advanced to the playoffs at the 2011 Boundary Ford Curling Classic, however they would lose the quarterfinal to Edmonton's Tiffany Odegard. Her team qualified for the 2012 Scotties Tournament of Hearts. At the 2012 event, Galusha would start off well, winning the 2012 Ford Hot Shots, and starting off with a 2-1 record in the first three games. After catching the flu, which was heavily circulating amongst all teams, Galusha would miss two games, one of which found second Wendy Miller sitting out with the flu, leaving three players on the ice. The team could not recover from Galusha's absence and would finish round robin with a 4-7 record. Although the team finished with a disappointing record, it would mark a second occasion for Galusha defeating the defending champions, Team Canada (Amber Holland) during round robin. Marking the fourth time in history, a team from the Territories would achieve this. They would also defeat the eventual champions, Team Alberta's Heather Nedohin. The team returned to the Scotties once again in 2013. At the 2013 Scotties Tournament of Hearts, they would finish with a 2-9 record, but once again defeated the defending champion along the way, when they beat Nedohin for the second straight year.
