Christopher (Chris) Gretina
Founder & Principal Attorney
A Career Defined by the Search for Truth
A graduate of Harvard Law School and Duke University, Chris has spent nearly twenty years cultivating a deep range of investigative experience. His perspective is uniquely multidimensional. Chris led sensitive compliance investigations in-house at Pfizer for nearly a decade, managed hundreds of corruption probes as an Inspector General with the New York City Department of Investigation, prosecuted felony cases as an Assistant District Attorney in Manhattan, and navigated complex corporate investigations at two top international law firms.
Effective investigation requires more than just a legal mind. It requires a commitment to objectivity and a steady hand.
Throughout his career – whether in government or the private sector – Chris has been driven by a singular passion: diving into the details to figure out exactly “what happened.” Chris founded Blue Rose Law to bring that dedicated focus to every engagement.
At Blue Rose Law, your matter is never handed off to a junior associate. You get the strategic insight of a seasoned investigator who prioritizes prompt, thorough, and efficient fact-finding. From the initial evaluation of a complaint to the completion of a complex investigation, every review is conducted with a neutral eye and anchored by integrity.
Chris’s Prior Experience
-
Chris has a deep understanding of compliance issues in the life sciences, particularly in the commercial space. Prior to starting Blue Rose Law, he spent nearly a decade conducting investigations in-house at Pfizer. With responsibility for the US docket, Chris reviewed and triaged complaints, investigated potential violations of law or policy, and shared findings with senior business leaders to ensure effective remediation. While centered on healthcare compliance, Chris’s investigative oversight extended to sensitive workplace matters involving potential corporate policy violations, professional misconduct, and issues within corporate support functions.
As US Investigations Lead, Chris regularly advised other attorneys on strategy and managed investigative obligations under the company’s Corporate Integrity Agreement. He also led key workstreams to develop the company’s global investigations playbook, strengthen the team’s practices for preserving attorney-client privilege and attorney work product, and improve protocols for virtual investigations. During his final year at Pfizer, he served at various points as US Compliance Lead for the Oncology, Rare Disease, and Hospital business units, advising senior leaders on proactive risk management.

Prior to joining Pfizer, Chris served as an Inspector General at the NYC Department of Investigation, where he worked to rein in public corruption. Managing a squad of approximately twenty attorneys, investigators, and financial analysts, he had oversight of thirteen City agencies, including the Department of Health and Mental Hygiene and all of the City’s finance agencies.
As Inspector General, Chris triaged many complaints and directed hundreds of investigations into suspected illegal activity and misconduct such as fraud, bribery, and bid-rigging. For each matter, he managed strategy and delivered findings – personally leading the most sensitive cases while supervising his team through every stage of the investigative process. Upon completion of each matter, he issued public reports, worked with agency leaders on remediation, and coordinated with state and federal prosecutors on criminal referrals. He also leveraged investigative data to identify systemic trends and provided training to DOI staff on legal issues and investigative report writing.

Chris served the public as a criminal prosecutor in the Trial Division of the Manhattan District Attorney’s Office. In this role, he handled all aspects of felony prosecutions, from initial case assessment and grand jury presentations to conducting hearings and trials. Formally trained and designated for domestic violence cases, Chris also served as an instructor, presenting training lectures to incoming classes of prosecutors.

Earlier in his career, Chris gained foundational experience at two prominent law firms, where his practice centered on corporate internal investigations and complex litigation. On a significant tax fraud audit, he personally managed all aspects of the internal investigation, including presenting the client’s case to the government. He also contributed to large-scale defense teams in high-stakes matters, including an FCPA prosecution and complex securities fraud actions.

Shortly after law school, Chris served as a law clerk to Chief Justice Christopher J. Armstrong of the Massachusetts Appeals Court. He assisted with all aspects of appellate review and drafted published opinions for both criminal and civil cases.
