Timberline Knolls is an inpatient or “residential” mental health treatment center for women located in Lemont, Illinois. Timberline Knolls provides treatment for women and girls starting as young as age 12.  Timberline Knolls offers intensive residential treatment for a variety of mental health-related disorders, including eating disorders, drug addiction, trauma, and other problems.

The Timberline Knolls residential facility sits on 43 wooded acres in Lemont, Illinois, in the western suburbs of Chicago. Give them credit for one thing: the facility is very well maintained and it is supposed to offer a sense of calm and peace to help patients with their recovery.

So it would seem like a decent place to take your child. It all sounds good until you dig a little deeper.

History of Sexual Abuse at Timberline Knolls

In recent years, Timberline Knolls has faced a growing number of allegations involving sexual abuse of patients. Most of these allegations have involved claims of inappropriate relationships between residents and staff members and downright sexual assault and abuse.  Some of the incidents have involved sexual abuse of minor residents and/or sexual assaults committed by staff members. These allegations have led to various investigative reports detailing how staff members at Timberline Knolls have preyed on vulnerable residents at the facility.

In June 2024, a major congressional investigation report was released by the U.S. Senate Finance Committee regarding the problem of abuse at residential treatment facilities like Timberline Knolls. The Senate report focused on the major healthcare companies that own and profit from these treatment facilities, such as Acadia Healthcare, which owns Timberline Knolls. The report suggests that there is a systemic sexual abuse problem at these facilities.

Sexual abuse at Timberline Knolls has been a rampant problem that most likely involved numerous staff members at the facility over the years. There are at least two individual staff members, however, who have been specifically identified in civil lawsuits or criminal indictments: Erick Hampton and Mike Jacksa.

Erick Hampton

In August 2024, a civil lawsuit was filed against Timberline Knolls alleging that a staff member named Erick Hampton sexually assaulted a 24-year-old resident patient at the facility. The victim was in the facility for treatment for her bipolar disorder. The lawsuit claims that Hampton sexually assaulted her on 3 separate occasions.

The victim claims that she reported the sexual assault to administrators at Timberline Knolls, but no action was taken against Hampton. Instead, she claims that she was falsely accused of having a sexual relationship with another staff member which forced her to leave the facility.

Mike Jacksa

In 2019, another Timberline Knolls staff member, Mike Jacksa, was criminally charged with sexually abusing 6 female patients at the facility. Despite the emergence of allegations, Timberline officials waited three weeks before notifying law enforcement. In the interim, Jacksa was suspended and reinstated twice after internal investigations. Once police became involved, Jacksa was suspended a third time and eventually fired.

Police reports state that when Timberline staff discovered a patient’s journal describing her sexual encounters with Mike Jacksa, they confronted her while he was present. This confrontation caused the patient severe emotional distress, leading to a self-harm attempt and subsequent hospitalization. Standard treatment protocols all make crystal clear that individuals reporting sexual crimes should never be made to recount their experiences in front of the alleged perpetrator, underscoring a significant breach of procedure.

Timberline Knolls Is Part of a Larger Problem with Acadia

Acadia Healthcare owns Timberline Knolls. It is one of the largest providers of behavioral health services in the United States, operating over 200 facilities across the country, including residential treatment centers, psychiatric hospitals, and outpatient programs. It offers care for individuals with mental health issues, substance use disorders, and other behavioral challenges.

Acadia Healthcare has faced increasing scrutiny and legal challenges over allegations that it has failed to adequately protect residents at many of its facilities from sexual abuse and other forms of mistreatment. Specifically, numerous abuse lawsuits and investigations have surfaced, claiming that Acadia’s facilities have not taken sufficient measures to prevent sexual abuse by staff members or other residents. These allegations point to systemic failures in monitoring, reporting, and responding to abuse claims, raising concerns about the company’s ability to ensure a safe environment for vulnerable populations.

For survivors, the reality is heartbreaking. Vulnerable residents, many of whom are already battling mental health or addiction struggles, have been victimized in places meant to be sanctuaries. How could this happen? The answer lies in systemic problems that run deep within Acadia’s operations:

Key Allegations Against Acadia Healthcare Facilities

1. Failure to Monitor Staff: In many lawsuits, Acadia facilities have been accused of not properly vetting or monitoring staff members who interact with patients. In some cases, staff members who have been accused of inappropriate behavior or abuse were allowed to continue working, leading to further harm to residents.
2. Delayed Reporting: Acadia facilities have been criticized for delaying the reporting of sexual abuse allegations to law enforcement or appropriate authorities. In some instances, internal investigations were slow, and victims were left to endure continued abuse.
3. Inadequate Response to Abuse Claims: There have been numerous claims that Acadia facilities failed to take appropriate action when residents reported abuse. Instead of promptly addressing allegations and removing the accused individuals, there have been reports of staff being suspended or reinstated multiple times, as in the case of Timberline Knolls and former staff member Mike Jacksa.
4. Lack of Accountability: Internal investigations are frequently mishandled, with accused staff members being suspended or even reinstated after allegations. At Timberline Knolls, one staff member was reinstated twice before law enforcement was finally notified. That just cannot happen.
5. Unsafe Resident-to-Resident Environment: Besides abuse by staff, some allegations suggest that Acadia facilities have not done enough to prevent sexual assaults between residents. Lack of proper supervision, failure to separate high-risk individuals, and insufficient staff training have all contributed to unsafe environments where vulnerable residents are at greater risk of harm.
6. Systemic Issues of Understaffing: Understaffing is another key issue that has been highlighted in legal complaints. When facilities are understaffed, monitoring of patients becomes lax, and incidents of abuse and neglect become more likely. This systemic problem has been linked to the profit-driven model that some critics say prioritizes revenue over patient care.

These patterns of allegations indicate that the abuse occurring in Timberline Knolls are not isolated incidents but part of a broader issue of negligence in doing what must be done – including giving up some of Acadia’s profits – to protect this high-risk population from harm. The company’s failure to ensure a safe environment for patients, many of whom are already vulnerable due to their mental health or addiction struggles, has led to significant legal action, public scrutiny, and calls for reform.

Timberline Knolls’ Response to Allegations and Safety Measures

Timberline Knolls’ defense to these allegations is actually not “deny deny deny.”  In response to the claims of sexual abuse, Timberline Knolls has publicly acknowledged the need for greater oversight and stricter protocols. The facility says it has implemented new safety measures designed to protect residents, including enhanced staff training, stricter hiring processes, and increased supervision. Additional measures have been introduced to ensure that any complaints from residents are taken seriously and thoroughly investigated.

Despite these assurances, the effectiveness of these measures remains under scrutiny as many lawsuits continue to allege that Timberline Knolls failed in its duty to protect vulnerable patients. Families and advocacy groups are calling for more transparent and robust reforms to ensure the safety of residents in the future.

Victims Can File Sex Abuse Lawsuits Against Timberline Knolls

Anyone who was the victim of sexual abuse or assault while they were a resident patient at Timberline Knolls has the right to file a civil lawsuit. Victims of sexual abuse can file a lawsuit against the facility, and its parent company (Acadia Health), for negligently failing to protect them.

Facilities like Timberline Knolls have a legal duty—not to mention a moral obligation— to ensure that residents at the facility are reasonably safe and not the victim of sexual abuse by staff, or by other patients. Timberline Knolls habitually breached this duty which means they can be held liable for negligence in a sex abuse civil lawsuit.

Calculating Timberline Knolls Settlement Payouts

The value of a civil lawsuit against Timberline Knolls or its parent company, Acadia Healthcare, depends on several key factors. Each case is unique, but certain elements consistently determine how much compensation survivors may be entitled to receive. As plaintiffs’ lawyers, we know these cases are not just about money—yet settlement compensation (or a jury award) is the only thing we can get for you.  That is how every civil lawsuit by a plaintiff who suffered and injury works.  So in some ways, it is about the money.

Successful plaintiffs in a sex abuse lawsuit against Acadia can get financial compensation for the emotional harm and damage resulting from the abuse. The amount of money you can get from suing Timberline Knolls or other places for sex abuse depends on a few things. Here are the three main things that impact that money you will receive as settlement compensation or at trial:

• Evidence: If you have solid evidence to prove that the abuse really happened (other than your word) your case will likely be worth more money.
• Statute of Limitations: The statute of limitations (or SOL) determines how long survivors have to file a lawsuit. In Illinois, the SOL for child sexual abuse cases gives survivors until age 28 or 3 years after discovering the abuse. However, this timeline can create unnecessary barriers, especially when survivors need years to process their trauma and come forward. Legislative changes may further extend these time limits, but survivors cannot wait without real risk of losing your legal right to seek justice and a settlement payout. If you are unsure whether your case is within the SOL, call us or any other lawyer so we can help you determine your eligibility.
• Severity: This is what really drives settlement payout in residential treatment center sex abuse lawsuits. The severity and frequency of the abuse are major factors. Cases involving repeated, prolonged abuse or particularly egregious misconduct are typically valued higher because the harm caused is more extensive. At Timberline Knolls, many survivors have reported years of mistreatment, often involving staff members who exploited their positions of power and did not make a lot of effort to hide it.  The abuse was not  isolated or rare—it was part of a larger pattern of failure to protect children.
• Impact: The impact on the victim, including physical injuries, psychological trauma such as PTSD, depression, and anxiety, will also drive up the potential settlement value of a case.
• Age: Younger victims will typically receive higher settlement payouts because of the long-term impact on their development and life trajectory.
• How Awful the Center Was: Our lawyers like the cases involving Timberline Knolls more than most residental treatment center sex abuse lawsuits. Why? Acadia owns it.  It is fair to say Acadia has a lot of skeletons in its closet and should want to settle these Timberline Knolls lawsuits quickly.
