About John
John Martoccio has practiced law in Illinois since the 1970s. He completed his undergraduate studies in political science at Northwestern University School of Law in 1970 and earned his J.D. from The John Marshall Law School in 1973. Those academic years set the foundation for a long legal career centered in the Chicago suburbs.
His professional life has been anchored at the Law Office of Martoccio & Martoccio, where he serves as managing partner and lawyer. He oversees the firm's work and continues to handle client matters personally. Colleagues and clients see a lawyer who balances casework and firm management, handling the daily demands that come with running a smaller practice.
Martoccio's affiliations reach back decades. He has been a member of the American Bar Association since 1973, a tie that dates to his earliest years in the profession. More locally, he joined the DuPage County Bar Association in 2003 and remains an active member. Those memberships have kept him connected to changing rules, court procedures, and developments in Illinois law.
He works from a Hinsdale office. The location positions him close to both suburban and county courts, and it serves as the base for client consultations and case preparation. He is admitted to practice in Illinois and maintains his practice within that jurisdiction.
Over the years Martoccio has managed a variety of matters typical of a long-established suburban practice. He brings an experienced eye to procedural matters and to the daily work of preparing cases for negotiation or trial. He has handled litigation and transactional work for local clients and navigated the practical challenges that come with those files.
He is known for a steady approach and for handling the administrative side of a law firm alongside his casework. Younger attorneys at the firm have worked under his supervision on discovery and courtroom preparation. His career spans decades of change in courts, technology, and practice norms, and he has adapted his practice to those shifts while continuing to serve clients in the region.
He currently practices from his Hinsdale office, representing clients in matters across Illinois.
