Mental Health Organization and Its Leaders Sued for Alleged Sexual Exploitation of Vulnerable Client

GARDEN CITY, N.Y. – June 29, 2026 – A lawsuit filed today in Nassau County Supreme Court levels devastating allegations against the Mental Health Association of Nassau County, Inc. (MHANC) and two of its top executives, accusing them of sexually exploiting, financially manipulating, and retaliating against a vulnerable client who depended on the organization for treatment, housing, and employment.

The plaintiff, a Nassau County woman with a psychiatric disability, is proceeding anonymously under a pseudonym to protect her from potential further harm. The complaint, filed under Index No. 613598/2026, seeks both compensatory and punitive damages, asserting a staggering twenty-three causes of action that include sexual harassment, fraud, negligence, breach of fiduciary duty, and assault and battery.

"This case is about the abuse of trust," said James E. Toner, Esq., one of the attorneys representing the plaintiff. "The people our client relied on exploited her vulnerability, and we intend to hold them accountable."

Shocking Allegations of Exploitation and Abuse

The lawsuit details a disturbing series of alleged actions by senior figures at MHANC, an organization with a stated mission to provide hope and services to the county's vulnerable populations. According to the complaint, Executive Director Jeffrey McQueen used his position of authority and the plaintiff's dependence on the organization to coerce her into a sexual relationship. The suit further alleges that McQueen sent her sexually explicit material and orchestrated a financial scheme in which he arranged for payroll checks to be issued to her for work she had not performed, then pressured her to return a portion of the funds in cash as an unlawful wage kickback.

Adding another layer to the allegations, the lawsuit claims the organization's Compliance Officer, Lisa Weiss, not only failed to intervene but actively participated in the exploitation. The complaint alleges Weiss solicited a controlled substance that had been prescribed to the plaintiff. Weiss, whose role is formally titled Director of Quality Improvement, Compliance, and HIPAA Privacy Officer, is also accused of threatening the plaintiff's housing situation after an internal investigation into the matter began.

"Institutions that serve people with mental-health disabilities owe them a heightened duty of protection," stated Terence C. Scheurer, Esq., who has joined forces with Toner on the case. "The allegations describe a profound failure of that duty."

Oversight Under Scrutiny at Decades-Old Institutions

The lawsuit brings intense scrutiny upon the internal controls and ethical culture at MHANC, a non-profit founded in 1953. The organization, which provides a wide array of services including residential programs, crisis support, and financial management, receives a respectable 3-out-of-4-star rating from the watchdog group Charity Navigator. However, a review of public feedback reveals some prior concerns. A year ago, several negative Google reviews described issues with the organization's financial and housing services, with one user calling it an "absolute scam agency" and another warning, "Don't get housing with this program! They will rip your family apart!" While anecdotal, these comments touch upon the same areas of housing and financial management now at the center of the lawsuit.

Also named as a defendant is the Clinton Housing Development Company, Inc. (CHDC), a Manhattan-based non-profit focused on creating and preserving affordable housing. CHDC, which holds a 2-star rating from Charity Navigator, has also faced public criticism. A May 2025 Manhattan Community Board meeting documented numerous tenant complaints across several CHDC buildings, citing repair delays and other issues causing "significant mental and emotional distress." The company has also been a defendant in several past lawsuits, including a 2021 federal civil rights case. The connection between the Nassau-based plaintiff and the Manhattan housing organization is not yet clear, but CHDC's inclusion in the suit suggests its role in providing housing was intertwined with the services offered by MHANC.

As of this report, none of the defendants—MHANC, CHDC, Jeffrey McQueen, or Lisa Weiss—have issued a public statement in response to the allegations.

A Legal Battle Within a Strict Regulatory Framework

The legal battle ahead is poised to be a significant test of institutional accountability in New York's heavily regulated mental health sector. The plaintiff's legal team, combining 65 years of trial experience, is seeking punitive damages to punish the organization for what the complaint calls a "reckless disregard for the vulnerable patients in its care."

The case unfolds within a legal landscape that explicitly acknowledges a heightened duty of care for individuals with mental disabilities. The New York State Office of Mental Health (OMH) licenses and regulates thousands of programs like MHANC, setting minimum standards for safety and care. Furthermore, the New York State Justice Center for the Protection of People with Special Needs was established specifically to investigate and prosecute allegations of abuse and neglect against vulnerable persons in state-certified facilities. New York's Penal Law also criminalizes the endangerment of a vulnerable or disabled person by a caregiver, particularly in cases involving sexual contact.

This robust regulatory framework underscores the gravity of the allegations. The lawsuit's success could hinge on proving not just the alleged actions of the individuals, but a systemic failure of the organization to uphold its legal and ethical obligations to protect its clients from harm. The case highlights the critical importance of oversight, compliance, and the profound power imbalance that can exist between vulnerable clients and the institutions they are taught to trust.
