Timberline Knolls Closing Feb. 13

LEMONT, IL — Timberline Knolls Residential Treatment Center, which has been embroiled in several controversies over the last few years, is closing Feb. 13, according to a statement from Acadia Healthcare, which owns the facility.

“Acadia has made the decision to close its Timberline Knolls facility located in Lemont, Illinois, effective Feb. 13, 2025. This decision followed a careful and comprehensive review of the current landscape for the programs and services offered by Timberline Knolls," a statement from Acadia reads. "Prior to closure, Timberline Knolls will continue to work closely with patients, families and receiving facilities, providing direct care to make this transition as smooth and supportive as possible. Our clinical teams will collaborate with state and local agencies, as well as national and community partners, to verify the best alternative facilities that can provide comparable behavioral care services to fit the specific needs of each patient whose treatment extends beyond Timberline Knolls’ last operating day.”

The facility was acquired by Acadia Healthcare in 2012, but had been opened under different operators since 2006. Timberline Knolls specializes in treating women and girls with mental health disorders, including mood and trauma disorders, eating disorders and addiction.

The facility has faced several controversies, including being named in an August 2024 lawsuit alleging a staff member repeatedly sexually assaulted a patient.

Another employee of Timberline Knolls, Michael Jacksa, is facing over 60 charges in several different cases, including charges of criminal sexual assault and criminal sexual abuse.

When asked about the facility last year, Lemont Police said it had received 546 calls for service from Timberline Knolls over a year's time.
