Save the date, the 2nd Annual Mount Sinai Lacrosse Alumni games are set for June 17, 2017.

If your a Mount Sinai HS Alumni login and register to participate! 


Welcome to the Mount Sinai Lacrosse on-line registration process.

We would like to thank you for your interest in participating in the Mount Sinai Lacrosse Program.  Our goal is to help our young athletes build strength in the game, as well as confidence on and off the field.  The high standards we set for ourselves, as mentors will hopefully help establish great habits in behavior on and off the field.

This on-line system has been implemented to make everyone’s lives easier and will allow you to create your own user account that you will continually use for registration purposes.  You can then sign in, pay fees, and volunteer for all the upcoming lacrosse programs.  We will now be able to track uniform numbers, positions, US Lacrosse membership #'s, email address...etc.

Payment for registration can be made using a major credit card (Visa and Master Card).

We would like to have everyone in our program registered on this system.  Once registered you will simply log in, choose the program you would like to register for (example winter, spring, or summer travel lacrosse), pay the fees and you will automatically be added to the roster.

We look forward to seeing you on the fields and if you have any comments or concerns please contact Peter VanMiddelem (President), James Carretta (Boys Director), Chris Chamberlain (Girls Director) or myself.

Thank you,

Bob Hagenberger
(Vice President)
