José P. Sierra


José Sierra focuses his practice in the areas of white collar criminal defense, pharmaceutical and healthcare compliance and business litigation. José’s broad and varied background as a federal prosecutor, an in-house attorney and corporate officer and an outside practitioner at a major national law firm provides him with a unique breadth and depth of experience to ably represent clients and resolve complex legal problems.

José has particular expertise in the areas of healthcare fraud and life science compliance and, over the course of his career, has advised healthcare and pharmaceutical industry executives, audit committees and corporate board directors on legal, employment, compliance and business strategies. He has also represented clients under government investigation, litigated shareholder and business disputes, and counseled life science and healthcare companies, including providing due diligence advice in connection with corporate acquisitions. José is fluent in Spanish, a skill he uses to assist companies from Spanish-speaking countries that conduct business in the United States.

Prior to returning to private practice and joining Laredo & Smith, José served as the Senior Vice President and Chief Compliance Officer for Sepracor (now Sunovion Pharmaceuticals) and Kos Pharmaceuticals, establishing those companies’ compliance programs and departments, and was previously the Director of Litigation at Schering-Plough, where he managed the company’s mass tort and commercial litigation. José also spent a dozen years as an Assistant U.S. Attorney in Newark, NJ, investigating and trying numerous high profile cases, including:

  • The first successful prosecution in professional boxing in more than 40 years and which was featured in an A&E documentary
  • Two related racketeering and public corruptions trials for which he received the Department of Justice’s Director’s Award for Superior Performance.

Following law school José served as a judicial law clerk to the Honorable Reynaldo G. Garza, U.S. Court of Appeals for the Fifth Circuit and, from 1997-2007, taught White Collar Crime at Rutgers Law School, where he served as an adjunct law professor.

José speaks frequently on corporate compliance, whistleblowing and corporate investigations, and is the former blogger on Pharmarisc, which offered cutting-edge analysis on legal and compliance issues in the life science industries.

José is a graduate of the University of Notre Dame and Cornell Law School. A native of Washington, D.C., José lives with his wife and children in the greater Boston area.
