Dr. Orsini’s commitment to the field of oncology led to the opening of the first dedicated oncology unit in the North Jersey area at the Clara Maass Medical Center, where he is director of oncology. In 2013, he was appointed to the University Hospital Board of Directors and serves on the Quality Care, Strategic Planning, Audit, and Governance and Ethics Committees. After treating the father of world-renowned tenor Andrea Bocelli, Dr. Orsini opened an office in Bologna, Italy. His work in Italy led to the publication of one of the first medical reports on the adjuvant treatment of node-negative breast cancer with systemic chemotherapy. His efforts were recognized and rewarded by the dedication of the Camera di Benessere (Room of Healing) by a grateful Mr. Bocelli at the Clara Maass Medical Center. Dr. Orsini continues to travel to Italy regularly for consultative work. He and his wife, Marie, have four children: Tiffany Orsini, Esq.; Lisa Orsini, Ph.D; Noelle Orsini; and Dr. James Orsini Jr. He is the proud grandfather of James Rocco, and twin granddaughters, Katherine and Renee.
