Best Lawyers Honors Nearly 250 Cozen O'Connor Attorneys in its Best Lawyers in America 2027 Edition

Best Lawyers selected 247 Cozen O’Connor lawyers from 26 of the firm’s U.S. offices for inclusion in the 2027 edition of The Best Lawyers in America and Best Lawyers: Ones to Watch in America.

James focuses his practice on complex federal court litigation, with an emphasis on health care‑related disputes and fraud investigations, particularly within the health care and insurance sectors.

James has extensive experience across all phases of the investigative and litigation process, including pre‑suit investigations, the identification of fraudulent activity, and the development of recovery theories. His work frequently involves matters arising from predetermined treatment schemes, patient brokering arrangements, and violations of Florida’s health care regulatory framework, including the Patient Self‑Referral Act and the Health Care Clinic Act. He has also handled disputes involving unlicensed activity and illegal ownership structures, among other forms of alleged misconduct.

James is experienced in litigating complex disputes in federal court and regularly advises clients navigating investigations that require a detailed factual record and a strategic approach to enforcement and recovery. His practice is shaped by a deep understanding of health care compliance issues and the regulatory environment governing providers and insurers.

Before joining Cozen O'Connor, James served as senior counsel in the Insurance Fraud and Recovery practice of another Am Law 100 firm. He earned his J.D. from the University of Miami School of Law and his B.S. from the University of Florida.
