Lauren Mack is a partner in the firm's White Collar Criminal Defense, Government Investigations and Healthcare Litigation practice groups. She has a broad range of skills in criminal investigations, litigation, healthcare fraud and abuse, and extensive trial experience.

A culture of compliance is a healthcare organization’s first line of defense in any oversight action. Lauren works with healthcare organizations and medical practices that require guidance in establishing and maintaining up to date compliance programs. She assesses existing ones, analyzes needs, makes recommendations and aids in the development of a compliance manual.

Lauren guides appropriate responses to subpoenas, audits, and civil investigative demands to ensure cooperation. Her valuable knowledge of local and federal agencies aids in the resolution of criminal and civil matters.

Lauren has 25 years of trial experience in the King’s County District Attorney’s office, where she prosecuted cases including but not limited to: sex crimes, child abuse, narcotics, larceny, robbery, and homicide.  Now in private practice she uses her years of trial experience to defend her clients’ rights. Additionally, she is frequently called upon to assist clients in the resolution of Administration for Children Services investigations.

Prior to her joining Moses & Singer, Lauren was an Executive District Attorney and served as Chief of the Healthcare Fraud Unit, Chief of Investigations, Chief of Crimes Against Children Bureau and Grand Jury.

During Lauren’s distinguished tenure in public service she managed and led complex investigations and prosecutions. She founded and directed a Healthcare Fraud Division where, as Chief of the Division, she led a team of investigators, prosecutors, and forensic accountants in the investigations and prosecutions of medical providers for Medicaid and Medicare fraud.  Lauren was also head of the Public Assistance Crimes Unit, prosecuting perpetrators of government frauds. Lauren's unit was known for pursuit of "Millionaires on Medicaid." Lauren was responsible for recovering over $10 million on fraudulent claims and assessing over 2000 allegations of fraud totaling over $18 million in alleged fraudulent claims.

Lauren established and maintained partnerships with many government enforcement agencies, including the U.S. Department of Health and Human Services Office of the Inspector General, the New York State Attorney General's Medicaid Fraud Control Unit, the Special Narcotics Prosecutors Office, NYPD, the New York City Human Resources Administration-Bureau of Fraud Investigations, the New York State Office of the Medicaid Inspector General, and the United States Attorney's Office-Eastern District of New York.
