He is an expert on sensitive and high-risk internal investigations for corporations, educational institutions, government agencies and non-profits.

At Kroll, Mark manages the full range of firm services, including complex financial and other sensitive internal investigations, policy and procedure reviews, litigation support, due diligence investigations, and corporate ethics and compliance monitoring. He has led many of Kroll’s highest-profile investigations, including sensitive sexual misconduct cases, investigations of the use of force by law enforcement (including by campus police), high-risk internal fraud, and confidential information leak matters. He has also helped recover tens of millions of dollars for corporate clients, helped non-profits ensure they are complying with the law and internal ethical obligations, and helped educational institutions understand key risk areas. His thorough, independent and evidence-driven approach is valued by clients worldwide.

Before joining Kroll, Mark served for 18 years as an Assistant U.S. Attorney, first in the District of Columbia, where he was part of a select group of prosecutors in the homicide and sex offense units, and later in the Eastern District of Pennsylvania, where he investigated and prosecuted narcotics trafficking, racketeering (RICO), money laundering, corporate fraud, identity theft, tax violations, and numerous other economic and violent crimes. For eight years, he was part of the Organized Crime Strike Force in Philadelphia, where he oversaw the investigation and prosecution of emerging criminal organizations and violent drug gangs.

Mark has also conducted and/or overseen dozens of Title IX-related investigations of alleged sexual harassment, sexual assault and stalking incidents at public and private universities and K-12 schools throughout the eastern and midwestern U.S. Some of Mark’s more high profile matters include leading an investigation of the University of Cincinnati Police Department following the shooting of an unarmed motorist in July 2015; reviewing admissions practices at the University of Texas at Austin following allegations of undue influence in the admissions process; and reviewing the North Carolina Highway Patrol’s hiring and selection process, ethical training and supervisory training protocols following media reports of trooper misconduct. Kroll’s findings and recommendations in each of these investigations were made public.

Additionally, Mark has investigated death threats against company executives and bomb threats against company facilities and has conducted risk assessments for workplace violence and crisis management situations.
