Hello Mavericks Families,

2021 High School Registration is OPEN! And pre-season practices are well underway so get registered, get on the field, and #BeMore

CLICK HERE to start your registration

With the 2021 spring season getting close to starting games we just wanted to send a few updates, requests, and reminders.



  • If you haven't registered yet please do so as soon as possible so your coaches have as clear a picture as possible of what their rosters look like for the season.
  • Registration fees are reduced to $250 this year and will be debited on May 1st once the season is in full swing.


  • At this time practices will continue for both Boys & Girls at Mountain View Champions park on the same nights of Monday, Wednesday, and Fridays 7:30-9:30 pm.
  • Both Boys and Girls teams will be getting into full team and systems practices starting next Wednesday, so it is important to participate in all practices (if possible) starting next Wednesday. Think of next Wednesday as the "Start of the Lacrosse Season".


  • With our official "in-season" practice window being so short (1 week) it is very important to be attending as many pre-season practices as possible. They understand many players are juggling other sports schedules and if you cannot make it to practice your coaches ask that you please communicate with them so they know when you will and won't be able to make it. Your coaches are starting to make game plans for game season and planning is very hard not to know who will be playing and who won't.


  • Please be sure to turn in a valid (less than 2 years old) Sports Physical and a Concussion Baseline Test. These can be obtained with your family physician or done through Portland Clinic.
  • Please turn these into your coaches on or before April 5th.


  • Because many players are involved in the modified schedule of school sports we are looking at low registration rates and we ask that all of you do your part to recruit as many new and returning players as possible. The more players on the field the better the development for all our players as well as the growth of the game, so get out there and get people signed up.


  • We want to remind all players that this year's registration was a one-time payment that will be debited from your card on file on May 1st. (Because that is a Saturday you may see the transaction a few days later, depending on your bank)


  • At the moment it looks like we will be able to watch our players this season. (YAY!) This applies to home games and we will plan to follow BSD's athletics spectator policy and will outline the policy in detail the week before games start.
  • We will continue to use Champions Park at this time, but it is looking like we will be able to play some or all home games on the Mountainside field and we will confirm game fields in the update the week before games start.

GEAR STORE: Click Here to Start Shopping.

  • Just a quick reminder that our gear store has a ton of great Mavs Lax items, including a few great mask options, to help support the club and help you look great while doing it.
  • 10% of all Gear Store sales go directly back to the club.
  • Many items have customizability such as player name and jersey #.
  • There are also some great gear bag options with our logo on them.


  • Uniform Distribution will be on April 5th for Boys & Girls teams during practice.
  • A Uniform Deposit check of $250 will be needed to checkout a uniform kit. (A reminder that if the full uniform kit is not returned your deposit check will be used to cover the cost of replacement.)

That is all for now. We wish all our Mavs Lax players the best of luck in their other sports and can't wait for the first face-offs of the season. Hoping you all stay healthy and positive as we get back to #BeMore with Mountainside Lacrosse.

-Your Mavs Lax Board
