Keidane McAlpine enters his third season at the helm for the Trojans, after leading the 2015 squad to its second-straight NCAA Tournament appearance and the program's third NCAA Sweet 16 Tournament bid.
McAlpine, the 2013 Pac-12 and NSCAA Pacific Region Coach of the Year, was named the new head coach of the USC women's soccer team on Dec. 16, 2013.
McAlpine came to Troy after serving the past two seasons (2012-13) as head coach at Washington State, where he guided the Cougars to back-to-back NCAA Tournament appearances and a program-best second place finish in the Pac-12 in 2013.
"We conducted a national search with a great pool of candidates, and Keidane really stood out with his vision of what he wants to bring to the USC soccer program," USC athletic director Pat Haden said of McAlpine. "He has already shown his ability to coach and succeed at the highest level, and his experience as a head coach in the Pac-12 is a big plus. We believe he is uniquely qualified to lead USC back to the successful level that we expect for our soccer program."
"Thank you to Pat Haden, Max Nikias and Steve Lopes for the opportunity to come to such a prestigious institution," McAlpine said. "I'm excited to get to work and be a part of the Trojan family. I thank (WSU president) Elson Floyd, (WSU Director of Athletics) Bill Moos and (WSU Senior Associate AD/SWA) Anne McCoy for all their wonderful support and guidance. It was great to work with the student-athletes at Washington State, and I thank them for their hard work and dedication. I'm looking forward to working with a new set of women with the goal of bringing the national championship back to USC."
Keidane (kuh-DAWN-ee) McAlpine (mik-AL-pine) is the fourth USC women's soccer head coach, replacing Ali Khosroshahin, who spent the past seven years (2007-13) at Troy. The Women of Troy won the 2007 NCAA Championship and have made 12 NCAA appearances, but have not reached the postseason since 2010.

In his first season at WSU, McAlpine went 6-4-1 in Pac-12 play and finished up 12-6-2 overall in reaching the 2012 NCAA Tournament.

In those two years, McAlpine coached six Cougars to All-Pac-12 honor rolls. Considered an offensive-minded coach, McAlpine showed his defensive savvy while at WSU as the Cougars finished 2013 ranked No. 7 in the nation with only 11 goals allowed.
Prior to Washington State, McAlpine spent six years (2006-11) as an assistant at Auburn, helping the Tigers to NCAA appearances each season along with three SEC West titles.

In 2004, McAlpine's fourth season as head coach at Birmingham-Southern, the team won the Big South championship and reached the NCAA Tournament, helping secure McAlpine honors as the Big South Coach of the Year. He helped develop 12 all-conference selections and a Big South Freshman of the Year recipient as the Panthers went 40-48-11 (.460) in the first five seasons (2001-05) in NCAA play. As an assistant at BSC during the Panthers' NAIA years, he helped the team to its first NAIA Tournament in 2000.
In all, McAlpine has spent seven seasons as a head coach (five at Birmingham-Southern, two at Washington State), having accumulated a 66-57-17 (.532) record at the helm of those two programs, with three NCAA appearances.
Active in Olympic Development Program for many years, McAlpine is currently on the Region IV staff with the '99 age group.
