We're the official girl's lacrosse organization for East Bellevue, including Newport, Sammamish, Interlake, International, and Big Picture High Schools and all elementary and middle schools feeding into these high schools.

NSI Lacrosse serves girl lacrosse players starting as young as 2nd grade through high school. We were founded as Bellevue East Lacrosse ("BeLax") in December 2005, by Emmett Soffey and Mike Reynolds, and continue to be supported by a dedicated group of parents. In 2015, we officially changed our name to NSI Lacrosse (Newport Sammamish Interlake) to comply with Bellevue School District and WIAA rules.

Some of us grew up playing lacrosse, others have grown to love the sport as we’ve seen our girls flourish through participation with this club. We think all girls and young women can benefit from a positive team sport experience, fitness, and fun. That’s what we’re about.

We started with a single middle school-age team, but have rapidly grown to include elementary, middle, and high school teams. Now, our high school program is sanctioned by the Bellevue School District, which means that girls who play at the Varsity level can earn a letter from their respective high schools. Our high school program serves girls at Big Picture, Interlake, Sammamish, and Newport high schools. Eventually, with continued growth, each of these high schools will have its own Varsity-level program.

We have a team for you!

We have a total of six teams in elementary, middle, and high school, including:

  •    8U:  K/2nd Grade Team (New for 2024!)
  • 10U:  3rd/4th Grade Team
  • 12U:  5th/6th Grade Team.
  • 14U:  7th/8th Grade Team.
  • High School Junior Varsity Team.
  • High School Varsity Team.

League rules vary depending on age group. Our coaches tailor drills and practices to the developmental needs of each age group.

  • While we have the support of the High School Athletic Directors and follow Bellevue School District policies, we are not a Washington Interscholastic Activities Association sport but rather a “club” sport. This means parents, a parent led board and coaches are responsible for the program. 
  • The official season for youth and high school typically starts the last week of February and typically ends mid-May for high school and Memorial Day for youth. No activities are scheduled during Bellevue School District's Spring Break.
