Andrew Leven has developed an extensive knowledge of the white-collar law enforcement and regulatory landscape through his experience as a federal prosecutor and defense attorney.

He has also served as the Worldwide Healthcare Compliance Director at the Cordis Corporation, an 8,000-employee medical device company then owned by Johnson & Johnson. At Cordis, Leven routinely participated in business decisions with the senior management team, trained all marketing and sales components, led sensitive internal investigations, and spearheaded the implementation of HCC policies that were later instrumental in negating qui tam civil lawsuits and government investigations.

During his extensive tenure as a federal prosecutor, Leven specialized in economic and healthcare fraud prosecutions.  He used his experience in the healthcare industry to help develop a nuanced prosecution decision tree for the off-label use of medical devices and drugs, and fashioned a novel legal theory that was successfully deployed in the largest physician bribery prosecution in the United States. 

Leven also conducted numerous insurance, bank, mortgage, wire, tax, and mail fraud grand jury investigations, acquired extensive trial experience, and served as the criminal tax intake prosecutor for the District of New Jersey. 

As a defense attorney he secured non-prosecution decisions for executives under investigation in the healthcare, insurance, and financial sectors from federal, state, and local law enforcement agencies. In a civil money penalty/disciplinary inquiry, Leven also persuaded financial regulators that a corporate executive acted inadvertently when providing materially incorrect information to them under oath, and should not be sanctioned, penalized, or otherwise disciplined.

In his practice, Leven uses these diverse real-world experiences and deep skill sets to seek favorable results for healthcare, corporate, insurance, and financial sector clients facing potential fraud-based criminal or civil challenges as defendants, plaintiffs, witnesses, and victims. 

Leven is a graduate of Syracuse University’s College of Law, where he graduated first in his class as the Valedictorian and served on the Law Review as the Editor of the Annual Survey of New York Law. He is admitted to practice in state and federal court in New Jersey, Pennsylvania, New York and Massachusetts.

Search Tips

Our Web site's search function employs a variety of techniques to help you make the most of your queries. In this tips section we use square brackets [ ] to signal queries, so [antitrust and litigation] is one query, while [antitrust] and [litigation] are two.

  • Exact phrases: Eliminate unnecessary search results by surrounding your search phrase with quotation marks. Placing ["project finance"] in quotes will return specific results and discard additional results that simply have the words "project" and "finance" peppered on a page.
  • Wildcard symbol: If you're not exactly sure how a piece of information you want is phrased, use the following symbol (*) as a word root expander. A search for [child*] will find not only "child," but also results with words like "children" and "childhood."
