Mt. Diablo Soccer is an all-volunteer youth soccer league serving the communities of Clayton, Concord, Walnut Creek and surrounding areas abiding by all AYSO principles.  Formed in 1980 we have served the local soccer community for more than 40 years as part of the American Youth Soccer Organization (AYSO). 

AYSO has been providing a world-class youth soccer program for more than fifty years based on our Six Philosophies of Everyone Plays®, Balanced Teams, Positive Coaching, Good Sportsmanship, Open Registration and Player Development. Built on the power of volunteer support, AYSO brings together community members to coach, referee and support their local Regions with the ultimate goal of creating a fun, family-friendly environment where your child can grow and develop not only their soccer skills but their leadership and social skills for life.

AYSO has the complete Player Development Pathway, which allows anyone, from toddler to adult to those with developmental disabilities to play the beautiful game we all love. Within this site, you will find all the information you need to find the program(s) that best suit your child and your family as a whole.

We look forward to having you join our AYSO family and becoming part of the World’s Biggest Soccer Club!
