The Girls Panthers Lacrosse Club was started by Seattle Prep parent John Verrilli in the fall of 1999. In their inaugural Spring season of 2000, 32 girls played in the JV Division of the Washington School Girls Lacrosse Association (WSGA) under head coach Stephanie Donkin from the University of Washington.  In the Spring of 2001, Stephanie Cone became their second coach and the team competed in both the Varsity and JV Divisions of the WSGLA.

Concurrently Matt Cone volunteered to coach the inaugural Boys Panthers Lacrosse Club that same year with Prep parent Hugh Bangasser as a representative for the Club and competed in the JV Division. Under the Cones leadership in the Spring of 2002 the Girls had a JV, B and A Varsity teams and won the Western States Tournament at Stanford University. That same year the Boys had JV and Varsity teams and won the Division 2 State Championship. Last season, the Cones returned for their 3rd and final year.  The boys continued with 2 teams and competed in the State playoffs finishing 3rd in Division; the girls  having 3 teams and repeating as Western States Tournament Champions at Stanford University and then winning the WSGLA Varsity State Championship at Seahawk Stadium. .
In 2002 the Girls and Boys Panthers Lacrosse Boards were formed comprised of many devoted Prep parents, and head coaches that helped support and expand the program to its current status and chaired by Eddie Travers in 2003. Prep parents Patti Travers will represent the Girls and M.A. Sangeorzan the Boys on the John Goodwin Club that advises Athletic Director Jeff Pietz along with other parents for the other Varsity sports at Prep this Spring. Prep had found something that quickly reached a tipping point with athletes from other sports and kids who just wanted to try something new.

As part of a five year process, this will enable Seattle Prep boys and girls, to be mentioned at school assemblies, gain respect from peers, and wear a varsity letter for a sport that includes more than 16 percent of the school.  The Panthers boys and girls boards put together a proposition accepted by Prep with input from various other athletic boosters for other sports.

Some important gains are:

• permission to bring sticks and store equipment on school grounds
• possibility of using school transportation
• validation for all student athletes involved
• posting of awards and accolades in the school gymnasium
• financial funding of equipment over time

This will be a gradual process fostered by the coaches at Seattle Prep and the Athletic Director focusing on the importance of recognition and support of Prep students.  Although, this is a major milestone, much work is needed to be done in the meantime.  Transition such as this can prove to be greatly beneficial to the program or detrimental if not handled well.

In addition, this spring the Seattle Prep Girls Lacrosse team will have a new Varsity Head Coach, Sarah Medwell, a 2003 graduate from the University of Denver and their Lacrosse program. The Seattle Prep Boys Lacrosse team will be led by Head Coach Fred Wilmot who assisted Matt Cone in the past and played Lacrosse at the Naval Academy.

Fred Wilmot, Head Panthers boys coach, had this to say, "My only hope is that other programs can benefit from the developments here at Prep.  We have a super supportive parents group, very motivated students, and an administration that sees the benefit of all this energy."  He adds, " Although this has the same challenges as going WIAA for a club Lacrosse program, I am very excited about the growth and support the Athletic Department has shown".
