    John joined the firm as a Litigation Advisor in 1993 after 20 years as a Justice of the Superior Court in Massachusetts. Prior to assuming his judicial responsibilities, he had been an active trial lawyer in both Massachusetts and the District of Columbia. John concentrated in corporate and commercial litigation, including matters involving antitrust, intellectual property, and securities law issues. As a former state and federal prosecutor, he also represented clients charged with so-called white collar crimes.

    Several years after his graduation from law school in 1958, he joined the full-time faculty at George Washington University Law Center where he ultimately became a tenured professor. His courses included evidence, equity, civil, and criminal procedure, property, and criminal law. In 1964, he left DC to join the US Attorney's Office in Massachusetts, and subsequently entered private practice in Massachusetts. In 1969, he became a lecturer-in-law at Harvard Law School where he taught until 1989. Over the last 25 years, he has also taught as an adjunct professor at Boston College, Boston University, Suffolk, and Northeastern University law schools. His courses included evidence, employment discrimination, and trial practice.

    John has always found it important to be involved in civic and bar activities.

    He was valedictorian of his class at Boston College. During law school, he was on the Georgetown University Law Review.
