Education
JD
Class of 1981

Located in New Haven, Connecticut, Yale Law School is one of the world’s premier law schools. It offers an unmatched environment of excellence and educational intimacy in the form of world renowned faculty, small classes, limitless opportunities for clinical training, and strong encouragement of public service. The Law School is small by design; its impact on the world is measured by its accomplished graduates and its ongoing scholarship and outreach through numerous centers and projects. For students, the experience is unparalleled. The faculty-student ratio supports a vast array of courses and opportunities for independent research and student-organized seminars. Students get practical training by representing real clients in clinics starting in their first year. Throughout, a spirit of collaboration reigns. All first-term courses are ungraded, and subsequent classes are graded honors/pass/low pass. Yale Law School is unique among law schools in that it produces leaders in all walks of life: distinguished deans and faculty members at law schools across the country and the world; industry CEOs and corporate counsels; founders of nongovernmental organizations and other nonprofit entities; entrepreneurs; government servants in federal, state, and local offices and the judiciary--just a few areas in which our alumni's talent and passion and dedication have made a difference. Among the School’s graduates are U.S. Presidents and Supreme Court Justices; and among its far-reaching projects, the Information Society Project and the China Center.

Class of 1978

The New York State Bar Association (NYSBA) is a voluntary bar association for the state of New York. NYSBA was founded in 1877 with the stated goal to cultivate the science of jurisprudence; to promote reform in the law; to facilitate the administration of justice, and to elevate the standards of integrity, honor, professional skill, and courtesy in the legal profession. Its first President was David B. Hill. Among the reforms in the legislation signed into law creating the association was the removal of the restrictions on the admission of women to the practice of law. In 1896, NYSBA proposed the first global means for settling disputes among nations, what is now called the Permanent Court of Arbitration in The Hague.
