Josselyn, a nonprofit community mental health center, has been serving people since 1951 when Dr. Irene Josselyn saw a need for kids and families to get help without worrying about the cost. Today, Josselyn is known for its excellent mental health care, offering outpatient therapy, psychiatry, case management, employment support and intensive programs for youth.

With 6 locations in northern Cook and Lake County, Josselyn is a high-quality affordable option serving more than 7,500 people annually. Due to our excellent programming, depth and breadth of services, financial strength, staffing and outstanding leadership, Josselyn was honored in June 2025 by being the only nonprofit named to Crain’s Chicago Business Fast 50 list for the second consecutive year.

Josselyn’s vision of providing Mental health for all reduces cost as a barrier to receive mental health treatment and support​. Josselyn works with every client to ensure access to care regardless of income and insurance, including a sliding fee scale based on eligibility.
