Ray Mateo, former Assistant U.S. Attorney, Returns to CK as Partner; Adds to the Firm’s Expanding White Collar Practice and Defense of Healthcare Providers

July 30, 2024

NEWARK, NJ: After nearly six years at the U.S. Attorney’s Office for the District of New Jersey, Ray Mateo has rejoined Calcagni & Kanefsky LLP as a Partner. His return to the firm adds to other recent hires and further expands the firm’s white collar criminal and regulatory defense and investigations practice, particularly as to the firm’s healthcare litigation and licensing focus.

As an Assistant U.S. Attorney, Ray served as Chair of the Office’s Opioid Abuse Prevention and Enforcement Task Force, leading federal criminal prosecutions, from investigation to jury trial, of healthcare and other matters involving allegations of Medicaid and Medicare fraud, anti-kickback schemes, bank fraud, wire fraud, identity theft, tax evasion, money laundering, and distribution of controlled substances. Ray partnered with and managed teams from the FBI, HHS-OIG, FDA, DEA, IRS, DHS and other federal agencies.

“Ray is a dear friend and extraordinary lawyer whose return to CK couldn’t come at a better time,” said Tom Calcagni. “With law enforcement’s increasing scrutiny of billing and prescribing practices of doctors, dentists, and other healthcare providers, we’re more and more called upon to vigorously defend our healthcare clients and protect their licenses. Ray has both the federal and state prosecutorial experience to contribute immediately to those important representations.”

Previously, Ray was Counsel with CK, representing clients in criminal and regulatory enforcement actions by the U.S. Department of Justice and U.S. Attorney’s Offices, New Jersey Division of Criminal Justice, New Jersey Division of Consumer Affairs, county prosecutor’s offices, and state professional licensing boards. Ray also served for four years as Deputy Attorney General with the Division of Criminal Justice of the New Jersey Office of Attorney General, pursuing investigations and leading prosecutions of the Division’s most complicated and high-profile criminal matters.

“We’re very fortunate, as are our clients, in welcoming back Ray to CK,” remarked Eric Kanefsky. “His deep government experience as both a former Assistant U.S. Attorney and New Jersey Deputy Attorney General boosts our already-strong team of former federal and state prosecutors. And the hard work and care he brings to every engagement is emblematic of the extraordinary effort and attention our clients rightfully expect.”
