About John A
John A Daller combines decades of medical training with recent legal training. He began his academic path at St. John’s University, earning a B.S. in Biology and Chemistry in 1981 and an M.S. in Biochemistry in 1983. He then completed an M.D. at the State University of New York–Downstate Medical Center in 1987 and a Ph.D. in Pharmacology, Toxicology and Immunology at the University of Arizona in 1995. He later turned to the law, completing a J.D. at Duquesne University School of Law in 2020.
Daller’s early career followed a clinical trajectory. He trained and worked in surgery and critical care. He holds certifications from the American Board of Surgery in General Surgery and in Critical Care. Those credentials reflect years of practice in operating rooms and intensive care units, and a command of high-stakes clinical decision-making.
The move from medicine into law came after an established clinical career. He pursued legal education in his later professional life and entered the Pennsylvania legal community after earning his J.D. His memberships include the American Bar Association, the Allegheny County Bar Association and the Butler County Bar Association. He also maintains professional connections in medical specialty circles tied to surgery and critical care.
That dual background shapes the kinds of matters he handles. Colleagues and clients describe a practitioner who can read medical records with the eye of a clinician and argue legal points with the training of a lawyer. He has experience in matters where medicine and law intersect, including issues that arise from clinical practice, patient care disputes and regulatory questions that implicate healthcare providers.
At the Daller Law Office he operates as a solo practitioner. The office is based in Pennsylvania. His practice draws on his medical credentials as much as on his legal training. He is comfortable working on cases that require careful review of clinical detail, expert testimony and an understanding of hospital systems and standards of care.
Daller’s path is unconventional but clear: extensive scientific and medical education, board certifications in surgery and critical care, a law degree earned later in his career, and a private practice that brings both disciplines together. He practices law in Pennsylvania, where his work focuses on medical-legal matters and related litigation.
