Bring on Spring!!! 
We are so excited to be offering the following options for this spring/summer!



We will be offering open gyms at the Isanti Middle School on the following dates:

February 27

March 6, 13

We have set up time slots based on birth year to split up the players, so they can hopefully get the most out of each session.  Based on participation numbers we may need to alter our times, but will communicate that with you as quickly as possible.  

9:00 - 10:00am - Birth Years 2002-2007

10:00 - 11:00am  Birth Years  2008-2010

11:00 - 12:00pm  Birth Years  2011-2013

Please note that due to COVID, we must have all players registered in advance for each session.  Please click on the registration for the dates below that you would like to attend.  Please note that we have a maximum of 20 players per session.  Players must be registered by 8:00pm the Friday before the open gym.  You may also edit your registration, if you find out you can not attend.
