Chair, Corporate Investigations and Integrity Practice

As Chair of Lowenstein Sandler’s Corporate Investigations and Integrity practice, Matt Boxer applies his public service experience in representing private clients in government and internal investigations. Matt is widely recognized for his impressive track record of leading fair and effective government investigations while serving for six years as New Jersey State Comptroller.

As New Jersey’s first independent State Comptroller, Matt oversaw a staff of more than 130 employees responsible for auditing government finances, examining the efficiency of government programs, investigating misconduct by government officers, scrutinizing the legality of government contracts and recovering improperly expended Medicaid funds. In that role, Matt and his staff produced a steady body of work that uncovered hundreds of millions of dollars in waste of taxpayer funds. The work of the office resulted in multiple new remedial state laws and was applauded by media outlets throughout the state.

Matt also has extensive litigation experience, having tried numerous cases to verdict and as a Federal prosecutor led the successful prosecution of numerous public officials on corruption charges. Among them were the “Monmouth 11,” a group that included three sitting mayors, four sitting councilmen and a police commissioner, making it one of the largest single-day corruption takedowns in state history.

Prior to his 2008 appointment as State Comptroller, Matt spent two years directing the state Authorities Unit, where he monitored independent agencies including the New Jersey Turnpike Authority and the Economic Development Authority. From 2001 to 2006, as a federal prosecutor, Matt served in the terrorism unit, the criminal division and the special prosecutions division of the U.S. Attorney’s Office. Prior to his public service roles, Matt spent four years as an attorney with Lowenstein Sandler, litigating criminal and complex civil cases with an emphasis on securities fraud.

Representative Engagements

Since his return to the firm, Matt’s engagements have included the following:
  • Represented the board of directors of a global communications company in conducting an internal investigation concerning the conduct of a senior official at the company.
  • Represented a state agency in conducting an investigation concerning a state contract and in resolving the state’s dispute with the vendor.
  • Represented a social media company in conducting an internal investigation concerning possible campaign financing violations.
  • Handled high-stakes litigation and related client counseling in a wide range of matters including white collar criminal, securities, defamation, bankruptcy-related, and government compliance matters.
Matt’s accomplishments as New Jersey State Comptroller include the following:
  • Conducted audits and investigations throughout New Jersey, across all levels of state, county and local government.
  • Led audits and investigations that found more than $100 million in Medicaid fraud each year in 2011, 2012 and 2013, and pursued and achieved recovery of those funds for taxpayers.
  • Identified cases throughout the state in which local governments wrongfully included contractors in the state pension system. In response to the report, Governor Christie, in August 2013, signed an executive order to create a Pension Fraud and Abuse Unit.
  • Led an audit that uncovered $43 million in waste at the New Jersey Turnpike Authority. The audit found, for example, public toll dollars being used to pay for an employee bowling league and for unnecessary employee bonuses such as for shoveling snow and for working on a birthday.
  • Oversaw an audit that focused on four government entities and found that none had properly evaluated their options for health care coverage and that, had they done so, they would have saved more than $12 million.
  • Discovered that more than 20,000 inmates in New Jersey’s jails and prisons were improperly paid nearly $24 million in benefits from government programs over a 22-month period.
