Lakeside Behavioral Health - O’Fallon Illinois

Lakeside Behavioral Health’s O’Fallon location is set to open on June 1, 2026, expanding access to care across the Metro East area, which has specialized mental health services. This location is designed to offer care closer to home while maintaining the same structure and oversight as their established program.

Structured Services That Adjust Over Time

Lakeside Behavioral Health brings outpatient psychiatry, individual therapy, deep transcranial magnetic stimulation (TMS), and a fully virtual intensive outpatient program (IOP) into one coordinated system. Care is not fixed, as providers stay aligned and adjust treatment based on how individuals are progressing week to week. Psychiatry supports medication stability through regular follow-ups, while therapy addresses patterns tied to depression, anxiety, trauma, and obsessive compulsive disorder (OCD) in ways that translate into everyday situations.For those managing both mental health and substance use, care for both is integrated into the same plan. Lakeside Behavioral Health also supports military members and first responders with local access and Tricare-supported care.

A Proven Model, Delivered Closer to Home

The O’Fallon clinic follows the same coordinated care model as Lakeside’s St. Louis location, where outcomes are tracked over time and many clients experience meaningful symptom improvement. By combining local access with virtual flexibility, Lakeside Behavioral Health helps people start care sooner, stay engaged, and build stability that holds up in daily life. Their virtual IOP adds structure through scheduled morning sessions, creating a steady starting point to the day while leaving space for work and responsibilities. The in-person clinic supports evaluations and treatments like deep TMS.
