More

White collar defense is all about delivering results when the stakes are high. Companies, boards, special committees, and individuals engage Cozen O’Connor’s White Collar Defense & Investigations practice to navigate their most serious inquiries. Whether managing an internal report of potential misconduct or a full-blown government investigation, our team is efficient, responsive, discrete — and, most importantly, effective.

360-Degree Perspective

Cozen O’Connor lawyers bring a critical perspective to every case. Our White Collar Group includes former federal prosecutors from large U.S. Attorney offices; a former deputy chief of the Civil Division of the District of Columbia’s U.S. Attorney’s Office; former federal prosecutors (and supervisory prosecutors) with DOJ and SEC; former state and local prosecutors; and a former assistant federal public defender.

Our practitioners have been on both sides of the table, so they know how white collar cases are built — and how they can be dismantled.

Government Enforcement

The goal for clients facing a government investigation is quite simple: prevent prosecution. Cozen O’Connor is exceptionally skillful at maintaining that focus. Having worked in government and formed professional relationships with government officials, our attorneys are able to identify persuasive arguments, narrow the scope of inquiries, limit exposure, and negotiate favorable resolutions.

In the rare event that prosecution is unavoidable, Cozen O’Connor’s team of veteran trial lawyers stands ready to vindicate our clients in court. Our attorneys have collectively tried hundreds of cases, both as defense attorneys and as prosecutors.

Internal Investigations

Cozen O’Connor regularly conducts complex internal investigations on behalf of corporate clients and is recognized by Global Investigations Review as one of the world’s top 100 investigations practices.

Our attorneys lead comprehensive investigations with speed. We set priorities, judge witness credibility, make factual findings, and help clients understand their potential exposure. In the end, we offer clients actionable, jargon-free advice, including whether to discipline rogue actors, self-report misconduct, revamp compliance mechanisms, or take other remedial protective measures.

Similarly, Cozen O’Connor provides sophisticated preventative compliance advice outside the context of an internal investigation.

Experienced Counsel

Over decades of practice, the team has accrued extensive subject-matter knowledge, including in the areas of criminal antitrust, international anti-corruption, trade sanction, False Claims Act, health care fraud and financial fraud statutes. Cozen O’Connor directs client strategy in the context of inquiries, investigations, and enforcement actions by federal, state, and local authorities, including DOJ, SEC, FTC, CFTC, executive agency inspector generals, U.S. attorneys, state attorneys general, and the U.S. Congress. 

Cozen O'Connor is very strategic and effective in how it manages cross-border issues on behalf of its clients... Always aware of current events and their potential implications.
