Redfern was inducted into the National Lacrosse Hall of Fame in September of 2018. During her playing days, Redfern was a two time Division III All-American at Ursinus College and was named Most Outstanding Player of the 1986 NCAA Tournament as she helped lead the Bears to a national championship. Following her collegiate playing experience, Redfern was a member of the US National Lacrosse Team from 1987-1993, and capped off her international play as a member of the winning United States World Cup Team in 1993, in Edinburgh Scotland.

As a coach, Redfern has led Lehigh to sustained success -- especially as of late. The Mountain Hawks have posted a 38-17 record from 2016-18, among the most wins in the nation over that three-year stretch. Most recently, the Mountain Hawks posted a 13-6 record in 2018, including a school-record seven Patriot League wins (compared to just two losses). For the second straight season, Lehigh earned the No. 3 seed in the league tournament, hosting a Patriot League Quarterfinal for a third straight season. Despite losing multiple key players to season-ending injuries, Lehigh won seven straight games spanning the end of the regular season and beginning of the postseason. The Mountain Hawks ended nonleague play with a thrilling 9-8 triple overtime win at Mount St. Mary’s followed by a 12-11 win at eventual MAAC Champion Fairfield. Lehigh followed by dominating Boston University in the Patriot League opener 15-8, handing the Terriers their largest-ever Patriot League defeat. Individually, sophomore Sondra Dickey emerged in leading the team in goals (54) and points (76) to earn first team All-League and second team All-Region. Dickey and Kayleen Kelly each broke the previous school record for draw controls in a season. Kelly broke Lehigh’s single-game (10), season (86) and career (169) records for draw controls, while Dickey added 81, each shattering the previous school record of 47. Both Kelly and Kierstyn Voiro were named All-Patriot League and Academic All-League, impressing on and off the field.
