Whether you are a parent, family member, alumni, business owner or just a fan of high school sports you can help provide a quality experience to our MHS athletes. We are all Wildcats!


About Big M Boosters – Big M Boosters is the parent booster organization for ALL Monrovia High School athletic programs. We aim to support student athletes and coaches through advocacy, recognition, scholarships, fundraising opportunities and providing needed support and equipment that isn’t being provided by other sources. 

Monrovia High School proudly offers 24 CIF recognized athletic programs with participation from approximately 350 students.  Big M Boosters is a non-profit organization and all funding comes through donations and volunteer-lead fundraisers. 


Our Purpose – Big M looks to promote community and sportsmanship between all athletic programs at Monrovia High School. We are proud to celebrate individual athletic achievements as well as team/program achievements on our social media platforms through our newsletter and our Athlete of the Month program. 

We advocate for better athletic budgets, coaches’ stipends and quality facilities and equipment for all athletes.

Each year we look to increase the number of scholarships we offer, tournament fees paid and coaches’ wish list items fulfilled as our funding permits. 

Proudly Brought to you by Big M
