“As a physician expert witness, I provide objective, evidence-based analysis and testimony in medical and toxicology cases across both civil and criminal matters. Drawing on extensive clinical experience and specialized knowledge, I help attorneys, judges, and juries understand complex medical issues, bridging the gap between scientific fact and legal interpretation. Whether retained by the plaintiff or defense, my role is to deliver clear, credible, and unbiased opinions grounded in current medical standards and peer-reviewed science.
Over the years, I’ve served as a testifying expert in a wide range of cases, including medical malpractice, personal injury, wrongful death, death in-custody, DUI, drug-related offenses, occupational exposures, and product liability. My background in Emergency Medicine, Trauma, Toxicology, Public Health, and Forensics allows me to assess causation, evaluate standards of care, interpret lab results, and explain mechanisms of injury or impairment with clarity and authority. I have been called upon to critique opposing expert opinions, review extensive medical records, and provide deposition and courtroom testimony that withstands rigorous cross-examination.
What I do well—and what sets me apart—is the ability to distill complex scientific material into language that is understandable and persuasive to non-medical audiences without compromising accuracy. I take pride in maintaining the highest standards of ethics, impartiality, and thoroughness in every case. With a reputation for preparedness, professionalism, and clarity, I serve as a reliable resource for legal teams seeking a strong, science-driven foundation for their arguments.”
