Programs offered
For Males ages 10-18
Emotional, behavioral, and mental health programs
When a child’s behavior becomes unmanageable—even with high levels of adult intervention, and even when the child is provided love, structure, and protection—that child is most likely experiencing emotional, behavioral, or mental health issues.
We are experts in working with youth who have ongoing emotional and/or behavioral manifestations, like aggression, self-harm, social withdrawal, emotional outbursts, inappropriate social interactions, inability to self-regulate/self-soothe, and suicidal tendencies.
Sexually problematic behaviors program
We specialize in working with kids who demonstrate sexually problematic behaviors. Our treatment program is based on the most current research and national standards, and our focus is on treating the whole child, not just a single issue. We’re committed to breaking the cycle of sexual harm so healing can begin. Learn more about our sexually problematic behaviors program.
Intellectually/developmentally delayed and special needs program
When a child is struggling with delays, it can be hard to know how to help. At Nexus, we create a safe space for kids to grow and advance, while gaining the skills and support they need.
Education and vocational programs

Vocational opportunities
Our youth are provided a range of ways to build life and job skills, from cooking to woodworking. They also participate in Kids Kare, a work-opportunity program that provides lawncare and snow-removal services in the local area—offering an opportunity to learn job skills and give back to the community.
Onamia Academy
Grades 4-12
We believe all students are capable of academic excellence. When youth are in our care, we prioritize their educational experience.
Onamia Academy is our on-campus school that serves youth receiving treatment with Nexus Family Healing. The school serves grades 4 through 12 and is focused on meeting each student’s individual needs. With small classes and tailored educational plans, students are supported in advancing their education, meeting graduation and diploma standards, and achieving their highest level of learning. When an Individual Education Plan (IEP) identifies a need for increased educational guidance, our academic resource room is equipped to support each student’s varying educational needs.
Our school is operated by the Onamia Public School System of Minnesota. Students’ graduation and credit requirements are governed by the local school district.

“This facility saved my family and me from plenty of what life and the court system can throw at an individual that has serious mental health conditions.” – Former Client

Empathy Is Essential in Residential Treatment
We are quick to judge parents, even when we don’t know the backstory. In residential treatment, we work hard to recognize the parent’s effort in trying to find help for their child, no matter how they show up throughout the treatment process.

Take Them for a Drive
Adolescent and teen boys are often navigating identity, belonging, and ideas of manhood. Communication can sometimes feel challenging as they explore who they are. Finding relaxed, low-pressure ways to connect—like spending time together in the car—can help open up conversation.
