The “Tomahawks Lacrosse” club was born using borrowed gear and practicing on any piece of green grass they could find. Three years later, after three All-League selections, two All-American honors and a spot in the North/South High School All-American game, Rorke was recruited to play at Syracuse for the legendary coach, Roy Simmons Jr.
Rorke lettered all four years at Syracuse,(1993-96), was a member of 2 NCAA Division I National Championship teams (1993/95) and was, in his senior year, a Team Captain and Honorable Mention All-American. After graduating from Syracuse, Rorke attended Navy Officer Candidate School and accepted follow-on orders to SEAL training in San Diego. After an action packed 13-year active duty career as an officer in the SEAL Teams, Rorke starred in the box office hit 2012 feature film “Act Of Valor” featuring active duty Navy SEALs in a movie based on real world SEAL adventures. His first book, ‘Damn Few: Making the Modern SEAL Warrior’ ended up on the NY Times Best Seller list.
He and his wife currently live in Southern California and Rorke is deep into his most challenging assignment, being a father of two beautiful little girls.

George was the President of the Club from 2000-2005. Under his leadership, the Diablo Scorpion lacrosse club became the largest lacrosse program in the Bay area in 2004, within five years and through the present the club is the largest individual club in the State of California. The program is thriving today with over 670 players enjoying the game annually.
From the inception of this new program through 2005, George was the head coach of several Scorpion Boys teams.

Later in 2006, he was honored as US Lacrosse Northern California Man of the Year, and was also awarded with the US Lacrosse “Excellence in Growing the Game Award” at the USL National Convention.
He continued as the Varsity defensive coach for the De La Salle Spartans through 2010, and proceeded to the NCS Championships in each of those years taking home 3 titles. He was named Assistant Lacrosse Coach of the Year by the Contra Costa Times in 2009. In addition, he continued his offseason coaching of the Norcal travel teams and led the Norcal U17 Team to its first Vail Championship at that age level in 2008.
He continued to volunteer his time off the field as well. From 2006-2010, he was an active Board Member on the NorCal Chapter of US Lacrosse Board. He actively promoted and supported the growth of the sport, coaching conventions and assisting the Chapter in supporting its members.
