Our Mission

Hanna transforms the lives of youth, families and communities impacted by trauma and adversity through resilience, connection and spiritual wellness.

Our Guiding Principle…

Hanna is an organization rooted in faith and the belief that all people are entitled to love, connection, dignity, respect and compassion regardless of their history, background or abilities.

All our actions and decision-making are guided by a set of principles.  These principles not only inform our work with the young people and families we serve, but also how we interact with all our stakeholders including staff, board, regents, volunteers, community partners, donors and vendors. The following represent our individual and mutual commitments to the Hanna Community:

  • Care and Heart – we are committed to providing the highest quality of care and offering an open heart to those we care for and those we care with.
  • Dedication – we are dedicated to giving every student in our care, and all the people our work impacts, the tools to build a productive and fulfilling life.
  • Trust, Honesty and Integrity—trust is the cornerstone of connection; all our actions should seek to build trust that we will do the right thing even if it is difficult; and that when we fail, we will make amends.
  • Equity – we deeply value the diversity of our students, staff and community partners, recognizing that our social and cultural groups inform our experience of, and healing from, trauma and adversity. We ensure access to resources and services that support every individual’s unique pathways to spiritual, emotional and physical well-being, with an appreciation and deep respect for the value of diversity and inclusion in creating a positive culture and better outcomes for all.
  • Empowerment and Collaboration – we provide opportunity and support for individuals to make decisions and take action to support their health and well-being, and actively dismantle barriers to personal agency, self-confidence and growth. We believe our strength and success is rooted in collaboration and a spirit of partnership, which informs our ability to make positive choices and results in personal, professional, and spiritual growth.
  • Respect – we accept each other for who we are, knowing that self and mutual respect is the bedrock of trust, safety and wellbeing.
  • Continuous Learning and Growth – we are committed to continuously growing our knowledge, learning from our successes and failures, and expanding our capacity to provide high-quality care and innovative services that are measurable, and continue to advance the health and well-being of our students, staff and community.
  • Responsibility and Stewardship – we manage our resources and honor the trust that others have placed in us by making thoughtful and prudent decisions that advance Hanna’s mission and the well-being of our internal and external stakeholders.
  • Safety and Stability – we create and offer a safe and stable environment for students, staff, and stakeholders with a commitment to non-violence and mutual respect in all interactions.
  • Transparency – we commit to open, honest, timely communication, and are forthright in acknowledging mistakes and joyful in celebrating success.

What is Hanna Boys Center?

Founded in 1945, Hanna Boys Center is a teen residential treatment center in Sonoma, California, with an on- campus accredited high school, Archbishop Hanna High School, serving 9th through 12th grade students with at risk youth programs.

The majority of Hanna’s residents have experienced high levels of adversity and toxic stress, including abuse, neglect, household dysfunction, family strife and community violence. A typical Hanna boy has experienced difficulties at home, fallen behind in school and struggled with interpersonal relationships. These experiences often result in strained family relationships as well as academic and social problems.

Many of our boys come from underserved and disadvantaged communities , mostly in Northern California. Boys who choose to attend Hanna must demonstrate a high level of motivation to create positive, permanent change in their lives.

Families commit to being actively involved in their son’s placement, including attending parenting groups and family therapy sessions. Regular home visits provide boys and their families the opportunity to practice newly acquired skills and promote important connections.

Campus Life

Hanna’s on-campus Archbishop Hanna High School staffed by specially trained teachers and staff. Founded in 1949, the school is fully accredited through the Western Association of Schools and Colleges (WASC). Class sizes are small, ranging from 8 to 10 students, so boys receive individualized help.

In their studies and daily lives, boys learn practical skills, as well as respect for their community and faith traditions of our program.

The boys live in housing facilities specifically designed for children with behavioral problems. These group facilities are on-campus units we call cottages and group homes. Each type of residence has several dedicated youth counselors, 24 hours a day, 7 days a week. Residence staff work 3-1/2 day shifts, sleeping inside their assigned residence, with the students.

In addition to serving as role models, our youth counselors help each boy develop socially appropriate behaviors—from using good table manners, helping with studying skills, maintaining personal hygiene, keeping their rooms clean—to fulfilling assigned chores. Boys are also taught a variety of life skills, including cooking, budgeting, finding employment and preparing for life away from a protected environment.

Hanna relies solely on private donations from individuals, private foundations and local corporations. Over 20,000 individual donors contribute every year. We receive no government or Church funding. Families are charged tuition based upon their financial situation, and boys are not denied admission due to a family’s inability to pay.


We envision a world in which every individual grows up resilient and healthy, regardless of circumstance.
