Catholic Youth Organization (CYO)
The Catholic Youth Organization (CYO) was founded in Chicago in 1930 to provide the youth a safe place to play and participate in organized athletic competition. CYO’s mission is to bring youth together, to foster strong relationships in families and communities, and to help them lead more fulfilling and rewarding lives through sports.
The Maryville CYO sponsors organized athletic programs throughout the year, notably basketball, cross country, track and field and cheerleading, utilizing facilities such as Catholic schools, YMCA, Chicago Park District and Chicago Public Schools.
Each year, approximately 3,000 youth, ages 8 – 19, participate in CYO events in the Chicago area. Maryville sponsors and directs this program on behalf of the Archdiocese of Chicago. It is open to young people of all faiths.

Exciting Partnership
Our Catholic Youth Organization (CYO) partnered with St. Martin de Porres to provide Westside H.O.M.E. Open Gyms. This is an anti-violence initiative designed to give youth in the neighborhoods of Austin and West Garfield a safe place to play, learn, and fellowship during the summer. Open gyms is designed for youth ages 6 yrs – 20 yrs and operated Mon – Fri from 10:00 a.m. – 4:00 p.m. and ran from June 19 – August 4, 2023. The H.O.M.E. program returned to Purcell Hall after a 2 year absence, due to renovations in the building. 87 youth showed up during the first week of open gym and 175 youth participated in the program. It was a safe and productive summer for all involved!
