Janine Tucker, a four-time IWLCA Regional Coach of the Year, is the all-time winningest coach at Johns Hopkins with a 169-68 (.713) record in 14 seasons, including an 101-51 (.664) mark at the Division I level. She took over the Blue Jay women's lacrosse program in August 1993 and successfully guided the program's transition from Division III to Division I without missing a beat. A 1989 graduate of Loyola (MD), Tucker has led the Blue Jays to double-digit win totals in each of her 14 seasons, including four NCAA Division III Tournament appearances, three ECAC Division I championship games, and the program's first three NCAA Division I Tournament appearances in 2004, 2005 and 2007. On March 18, 2006 Tucker became just the 12th coach all-time to reach the 150-win mark. She is just the sixth active coach to achieve the milestone.

The past four seasons have been the most successful in the history of the Johns Hopkins women's lacrosse program, as the Blue Jays have gone 47-23 against a lineup of nationally ranked teams. This past season, Hopkins again tied the school record with 12 wins, finishing with a 12-8 record. The Blue Jays advanced to the first ever American Lacrosse Conference title game, falling to eventual national champion Northwestern. Hopkins then made its third trip in four seasons to the NCAAs, advancing to the Elite 8 for the first time in school Division I history. Once again, senior Mary Key led the nation in scoring, finishing with a school record 121 points. She was a finalist for the Tewaaraton Trophy, was named the Attacker of the Year by the IWLCA and earned First Team All-America honors for the second consecutive season.

In 2006, Tucker guided Johns Hopkins to an 8-0 record to start the season as the Blue Jays climbed to #2 in the national polls. The team finished the season at 12-4 tying a school Division I record for wins in a season. Key led the nation in scoring for the second consecutive season and was a nominee for the Tewaaraton Trophy. In 2005, Hopkins went 11-6 including a 14-10 win at #6 Georgetown in its final regular-season game. The win helped the Blue Jays earn their second straight berth in the NCAA tournament, where they met the defending national champion, Virginia, in the first round. Hopkins led Virginia until the final minutes, but the Cavaliers pulled out a 10-8 win and eventually finished as the NCAA runners-up. Key ended the year as the nation's leading scorer in Division I, averaging 5.12 points per game.

A year earlier, the Blue Jays won a school Division I record 10 straight games to open the season and defeated four ranked teams, including #6 Notre Dame, the highest-ranked team ever defeated by Hopkins (the 2005 win over Georgetown matched that record). JHU also tied school Division I records for most wins and fewest losses in a season (12-5). Heidi Pearce became the third Hopkins player to earn All-America honors at the Division I level and the first Blue Jay selected to the first team.

Indicative of the steady improvement of the Hopkins women's lacrosse program, the 2004 season was a step up from 2003, when Tucker guided the Blue Jays to an 11-5 record that included a 12-2 win over #14 North Carolina in the final home game of the season. The Blue Jays finished the year ranked #17 in the Brine/IWLCA Poll, the fourth straight year they ended the season in the top 20. Tucker's 2002 squad finished 10-8 and advanced to the ECAC championship game for the third consecutive year. Hopkins won two games against ranked teams during that season, defeating #19 William and Mary 11-9 on March 9 and #13 Ohio State 11-10 on April 6.

The 2001 season was a benchmark as Tucker earned her 100th victory with a 13-9 win over #15 George Mason and two weeks later Hopkins won its first ECAC Championship as a Division I team, defeating Penn, 18-12, in the title game. The Blue Jays finished with an 11-6 record and a #17 rank in the final Brine/IWLCA Poll.

A year earlier, Tucker led the 2000 Johns Hopkins team to its first Division I postseason appearance as it reached the ECAC final and concluded its season with a 12-6 record and #16 national rank in the final IWLCA Poll. The 1999 Blue Jays posted a 10-4 mark in their inaugural Division I campaign. At the Division III level, Tucker guided the Blue Jays to the brink of the NCAA tournament championship game in four seasons. In Tucker's debut season, Johns Hopkins finished with its best record to date, posting a 16-1 mark and advancing to the 1994 NCAA Division III semifinals. Tucker led the Blue Jays back to the semifinals in 1995 and 1997 and to the quarterfinals in 1998. In five years of play in the Centennial Conference, Hopkins posted a striking 49-1 record, won four conference titles and finished undefeated in conference play in each of its four championship seasons.

Tucker and her staff have been instrumental in the development of the Blue Jay student-athletes on and off the field, including two players, Mary Ann McGuire and Laura Ekas, who never played lacrosse prior to arriving at Hopkins. In 1997, McGuire became the first JHU women's lacrosse player to be named NCAA Division III Defensive Player of the Year while Ekas earned a role as starter and captain.

Tucker has coached 23 IWLCA All-Americans, including IWLCA Division I All-America selections Key (2007, 2006 & 2005), Hentz (2005), Pearce (2004), Danielle Maschuci (2000) and Jamie Larrimore (2001). In addition, she has coached one IWLCA Defensive Player of the Year and one Attacker of the Year, four Centennial Conference Players of the Year, one ALC Rookie of the Year, 54 all-conference selections and 62 all-conference academic selections.

After a successful career as an All-American lacrosse player at Loyola, Tucker broke into the coaching ranks at her alma mater as an assistant. She helped coach the nationally-ranked Greyhounds for four seasons, and her success as an assistant for a prominent Division I power led her across town to Hopkins when the women's lacrosse position became available in 1993. Tucker was inducted into the Loyola Athletic Hall of Fame in March 1998 and is involved with the promotion of women's lacrosse through camps, clinics and speaking engagements. She is the director of the Johns Hopkins All-Star Girls' Lacrosse Camp each summer as well as the Elite 300 Camp, whose purpose is to bring together and instruct the nation's top high school girls' lacrosse players.

Tucker recently co-wrote a book with Maryalice Yakuchik entitled "The Baffled Parents' Guide To Coaching Girl's Lacrosse" which was published in February 2003. The book, geared toward youth, recreation league and high school coaches, details the progressive style of coaching women's lacrosse. Tucker is married to John Tucker, a teacher and lacrosse coach at Severn School. John was previously the head coach at perennial prep power Gilman and the athletic director at nearby Loyola Blakefield. He is a former Hopkins and United States World Team lacrosse standout, and former coach of the Pittsburgh Crossfire of the National Lacrosse League. Both Janine and John were inducted into the Greater Baltimore Chapter of the U.S. Lacrosse Hall of Fame in January 2003. The Tuckers have two sons, Ryan and Devin. Ryan is an ninth grader at Gillman and Devin is in eighth grade at Cathedral.
