Building a movement of strength, confidence, and community.

Box United uses boxing as a pathway for girls to unlock their full potential- inside and outside the ring.

Our Program: Fight Like a Girl

Fight Like a Girl is a school and community-based program that exists to solve three problems: limited access to sport for girls, rising mental health challenges, and declining confidence and self-esteem.

FLAG is the only all-girls boxing program that focuses equally on physical and mental wellbeing — using boxing to build discipline and mind-body connection, paired with our Social Emotional Wellbeing Curriculum, The Fighter's Mindset.

All programming is free for every participant. 100% of individual donations go directly to program delivery.

Our Story: Founded on the power of sport

Box United was founded in 2019 through a U.S. State Department grant designed to inspire leadership in girls around the world through sport. Mary Kate Vanecko founded Box United after completing a Fulbright fellowship in South Africa, inspired by boxing's power to unite communities.

In 2021, Box United evolved to focus exclusively on Chicago, launching Fight Like a Girl in 10 schools. Today we operate in 20 schools and three satellite gym locations, serving over 400 girls annually.
