Heartland Health Centers Thresholds

Thresholds offers two levels of outpatient substance abuse treatment — a standard Outpatient Program and an Intensive Outpatient Program (IOP) — giving people in recovery the ability to choose a level of structure that matches where they are in their recovery journey. The IOP is particularly well-suited for individuals who need more clinical contact than weekly sessions provide, including those stepping down from residential treatment or navigating early recovery while managing family, work, or housing responsibilities.

Located at 115 North Parkside Street on the West Side of Chicago, Thresholds is accessible to residents across Cook County and four surrounding counties. Office hours run Monday through Friday, 8:30 AM to 5 PM, supporting consistent engagement with treatment for people building or rebuilding stability in their daily lives.

A meaningful portion of people seeking addiction treatment are also managing mental health conditions — and treating only one side of that picture rarely leads to lasting recovery. Thresholds formally addresses co-occurring disorders and dual diagnosis, integrating care for conditions like trauma and PTSD directly into its substance use treatment programs. Cognitive Behavioral Therapy (CBT) anchors the clinical approach, giving clients tools to recognize and redirect the thinking patterns that contribute to substance use and emotional distress alike.

This integrated model matters especially for people whose substance use developed in the context of trauma, chronic stress, or untreated mental health challenges. By treating the full clinical picture within one recovery-focused setting, Thresholds positions itself as a recovery center where complex cases are the norm, not the exception.

Thresholds explicitly serves populations that many treatment programs overlook. Its substance abuse treatment programs are designed for men, women, youth and young adults, veterans, individuals experiencing homelessness, and Deaf individuals. This breadth of populations served is not incidental — it reflects a deliberate commitment to reaching people across different life circumstances and communities throughout the greater Chicago area.

Financial access is a core part of that mission. Thresholds accepts Medicaid and state insurance, and offers financial assistance for those who qualify. For families trying to find a recovery center that will actually accept their loved one and work within real financial constraints, these payment options make a concrete difference in whether treatment becomes possible at all.

Thresholds holds CARF accreditation, an internationally recognized quality benchmark for behavioral health and substance use treatment organizations. CARF accreditation signals that the center has undergone independent review of its programs, staff practices, and service outcomes — a meaningful credential for families weighing long-term recovery options in Chicago.

The organization's clinical and operational leadership includes Chief Medical Officer J. Wesley Cook, DO; Co-Chief Clinical Officer Peggy Flaherty, LCSW; and Chief Operating Officer Mark Furlong, LCSW. The presence of licensed clinical social workers in senior leadership roles reflects an organizational culture grounded in direct clinical practice and community-based care.
