HARRISBURG — Attorney General Dave Sunday announced that a Pittsburgh woman has pleaded guilty in federal court for attempting to overbill Pennsylvania Medicaid by falsely representing proper staffing numbers at residences used to care for intellectually and physically disabled adults.
Kelley Oliver-Hollis, 61, is the CFO and half-owner of SerenityCare LLC, which provides home and community based services to intellectually and physically disabled adults through the Pennsylvania Medical Assistance Programs. She pleaded guilty Monday to health care fraud. Oliver-Hollis is also required to pay $1.5 million in restitution at the time of sentencing on February 10, 2026.
“I commend the United States Attorney’s Office for their leadership that led to this successful outcome and I’m proud of the role our Medicaid Fraud Control Section played in both investigating and prosecuting this case,” Attorney General Sunday said. “Our office will continue to build on these strong partnerships with our federal partners to protect taxpayers and public programs like Medicaid by holding criminals accountable.”
The Pennsylvania Office of Attorney General’s Medicaid Fraud Control Section had a significant role in the investigation, along with the Federal Bureau of Investigation, and other federal, state and local partners.
SerenityCare operated six residences and a day program center within Allegheny County. The investigation revealed that between 2018 and 2023, Oliver-Hollis obtained authorization for increased billing rates for residents who required above average staffing ratios, yet almost never staffed the home sufficiently for the residents’ needs or as required by law. The homes also received numerous citations for unsanitary and unsafe living conditions for the residents.
Medicaid Fraud Control Section investigators from the Western Regional Office were a key part of the investigative team, supporting the work of the FBI, HHS, SSI, IRS, and Allegheny County District Attorney’s Office. Senior Deputy Attorney General Kee Song also assisted during the investigative phase, and Deputy Attorney General Nathan Michaux, who was recently appointed a Special Assistant United States Attorney, actively prepared with the assigned Assistant United States Attorney to assist in prosecuting the case in federal court.
Along with the Pennsylvania Office of Attorney General and the FBI, other investigative partners included the Allegheny County District Attorney’s Office, the US Department of Health and Human Services-Office of Inspector General, Internal Revenue Service-Criminal Investigation, Social Security Administration-Office of the Inspector General, and U.S. Department of Labor-Office of Inspector General.
The Pennsylvania Medicaid Fraud Control Unit receives 75 percent of its funding from the U.S. Department of Health and Human Services under a grant award totaling $12,839,940 for Federal fiscal year (FY) 2025. The remaining 25 percent, totaling $4,279,979 for FY 2025, is funded by Pennsylvania.
