Fall 2015 Registration Now Open!

Register now by selecting the appropriate button below.  

How to Register:  

Start the online registration process using one of the buttons above.  This will take you to our inLeague system and allow you to logon using your existing userid and password, reset your password, or register as a new user.

As part of the registration process, we ask every family to sign up for at least one volunteer role.  MDSA is run by a small core of volunteers that put in many hours each week to make sure all of the elements are in place to create a great soccer experience for you and your children.  However, we cannot do it without your help.  We are always in need of coach and referee volunteers to work with us to make this a successful program for everyone.   If you are interested in other volunteer roles, please let us know as there are many opportunities to make a difference “behind the scenes”.  Feel free to email us at

Our "guaranteed placement" registration period ends on June 15, 2015.  Make sure you register by then in order to ensure your child is placed on one of our Fall Soccer teams.  Players registered after June 15th will be placed on a waiting list and we will attempt to place the player on a team.  Teams will fill up fast so register today! 

2015 Registration Fees:

·   $125 per player Early Bird Special - must register by April 30th
·   $140 per player guaranteed placement registration June 14th
·   $175 Waitlisted Registration June 15th - July 31st

If you have never played with MDSA previously you will need to register your family in our online system by clicking here.   If you have registered a child with MDSA previously, even if your child did not play Fall 2014 or Spring 2015, you can click here to log in using your existing family profile (you can also reset your password if you have forgotten it).

Upcoming Elite Tryout Dates

The MDSA Elite Program is accepting applications now for the 2015 season! Registration is open to all highly motivated players wishing to play in a very competitive environment. Current Elite players, Select players, and other motivated soccer players from our area are encouraged to apply.

Elite teams compete against other Elite teams in the Bay Area during the season, as well as participate in AYSO, CYSA and US Club tournaments. Elite teams also play against Select teams and other U.S. Club teams. The Elite season will start soon after tryouts and end approximately in January of 2016. All of our Elite coaches are trained and licensed at the age appropriate level, following the nationally recognized AYSO Coaching Program.

If you want to further develop as a player, and play your soccer in a fun, enriching, yet competitive environment, then Elite soccer may be for you!

Dear MDSA Families,

As the Referee Administrator team, we want to welcome you to another fun and exciting year of soccer.  We know that no matter what skill level your child has in soccer, MDSA will work very hard to provide a fun, family friendly place for them to learn about soccer and themselves.

AYSO's Mission is to provide world class youth soccer programs that enrich children’s lives. As an ALL VOLUNTEER league, the key to our success is the willingness of ALL parents of children who participate to be actively involved in creating a successful environment for children and families.
