Welcome to Onarga Academy

Preparing Youth for a Healthy and Successful Future

Onarga Academy in Onarga, IL, offers boys a homelike environment where they can safely address their behavioral and emotional problems. Programming is built around a rich treatment culture that uses symbolism to connect with troubled adolescents and encourages lifelong learning. Progress is tracked through stages and may continue after treatment in a follow-up care program.

We integrate values, beliefs, norms, and ideals in all our programs, and we offer nondenominational services, chaplain visits, and religious service celebrations as requested by parents or residents.

Onarga Academy is situated on a beautiful, historic campus, where students live, eat, exercise, and go to school. They build relationships with counselors, teachers, and other students, and they attend individual, group, and family therapy to face their unique challenges.
