Casey Trombley-Shapiro Jonas
Casey Trombley-Shapiro Jonas has a multi-faceted litigation and advisory practice as an associate in Zuckerman Spaeder’s Washington, D.C. office. She brings passion, creativity, and strong interpersonal skills to her engagements—whether representing other lawyers facing legal malpractice claims, disciplinary proceedings, and ethical disputes, or drafting filings on behalf of clients in the food, drug, and health care arenas. With experience that ranges from drafting briefs and white papers analyzing complex statutory and regulatory issues to conducting direct and cross-examinations of witnesses and arguing motions in court, Casey is a confident and well-rounded advocate.
As a lawyer’s lawyer, Casey has an aptitude for putting her clients at ease, quickly building trust, commanding respect from those who know best what her job entails, and developing effective strategies that move cases forward. She represents individual attorneys and leading international law firms facing allegations of ethical breaches and legal malpractice. Her ability to listen carefully and thoughtfully, parse nuances in factual records, and develop creative legal strategies have led to successful outcomes.
Casey’s work in the food, drug, and health care space is informed by her belief in the importance of equitable access to medicines and care and her deep commitment to preserving patients’ rights. She has worked, for example, on behalf of numerous non-profits, trade associations, and advocacy organizations to preserve and support statutory programs designed to promote access to affordable, essential health care, including the 340B program, the Title X program, and the Hatch-Waxman Act.
