Mark Seppi

While attending UCSB in the late eighties I began playing lacrosse with the Gaucho Lacrosse Club in the West Coast Lacrosse League. After 4 years with Santa Barbara, I moved to Tahoe and joined the Tahoe Dawgs Lacrosse club playing in various tournaments for the past 27 years. During those 27 years I’ve volunteered with the Dawgs to help promote youth and high school lacrosse as well as help fund the HSLL. When Truckee reinstated their high school lacrosse club I began coaching the boys team. After 3 years with Truckee Boys Varsity I joined TNT Lacrosse and have been coaching Girls Varsity for the past 3 seasons.
I was fortunate to have Flip Naumburg as my coach at UCSB and his passion for the game and energy is something I want to bring to the field while I’m coaching. No matter what your role is on the team, your part of the family and you play for each other.

Aimee Dewan

Coaching Style: 
- Well balanced coaching style between focused and fun, as well as enforcing discipline and hustle. My goal is for the girls to work together as a team, understanding they win and lose as a team. Supporting individual players to play at their own highest level while feeling a sense of responsibility to her team. Support each individual's mental game and skill to be a strong contribution to the team and feel confident on the field. Believe the pieces that make up a great team are hard work, discipline and the idea of playing for the girl next to you.
Player-Coach Moment: 
- My biggest take away from my coaches is the importance of hustle, mental game, and playing for your team. They enforced the rules of never being out-hustled, no matter way the score is; stepping out on the field confident, never cocky nor scared; and always playing for the girl next you and your team, never individually.

My coaching style is a combination of preaching disciplined fundamentals, player development through heightened lacrosse IQ and implementing strategic team concepts. I believe that sports aides in individual growth by teaching student-athletes the concepts of time management, accountability, teamwork and "failing forward".

One thing that my high school coach, Mitch Whitely, said to our team that has stuck with me all these years is that there is nothing like playing for your high school team. The pride that you take in playing in front of your family, friends, teachers, schoolmates, and neighbors in your hometown is un-paralleled with any other experiences you have later on in college and beyond. Twenty-nine years and countless lacrosse games later this statement holds true and continues to resonate with me.


Darren Soi


Coach Soi is originally from the Hudson Valley area of New York State and moved to Tahoe in 2000 after graduating from St. Lawrence University in Canton NY, with a degree in Environmental Studies and Political Science.  At St. Lawrence, Darren played Midfield and specialized at the face-off position. 

Darren began playing lacrosse in 7th Grade and never gave it up, playing all 4 years at Clarkstown North HS and at St. Lawrence University.  Darren was a 3-year Varsity starter and captain of both his high school football and lacrosse teams, being awarded All-County, All-League and All-Section honors.  In the winter Darren participated in winter sports which ultimately led to his move west.

Darren began his coaching career in 2011 at McQueen HS in Reno.  Helping to start the program and grow the game in the region.  He coached for three years at McQueen before relocating for professional reasons.  Darren returned to coaching in 2015, coaching the Truckee Tribe U12 and U14 teams.  Last year Darren returned to the high school level as an assistant Varsity coach for TNT. 

Darren strongly believes in developing players to become contributing members within their community and preparing players for the future.  He believes lacrosse, like many team sports, is an avenue to help develop and support individual growth, focused on getting the maximum out of each player’s ability, while teaching players to work together to achieve a common goal. 

Coach Soi currently plays for the Tahoe Dawgs regional men’s club lacrosse team and enjoys supporting his son and daughter in the Truckee Tribe Youth program.
