Rosecrance Behavioral Health and North Central Behavioral Health Systems have signed a letter of intent to combine resources.

Under the affiliation agreement, LaSalle-based North Central would still oversee its operations, including staffing.

“We know there is a great need for behavioral health treatment, and this affiliation will allow us to combine resources to better serve and sustain the services for children, youth, adults and families in need of treatment,” Rosecrance CEO Dave Gomel said in a statement. “We are stronger together.”

North Central provides mental health and substance use services to more than 50,000 patients throughout north and west-central Illinois.

“Our organizations have known each other for many years,” CEO Jodi Mahoney said. “Together we have identified numerous synergies that exist between us.”
