About Lesse
Lesse Castleberry has been a fixture in New York’s legal community for decades. He arrived there after a steady climb through three law schools and over half a century in practice. His academic record begins with a bachelor’s degree earned in 1966 at the University of Arkansas. He went on to receive a J.D. from Harvard Law School in 1969. Six years later he completed an LL.M. in Taxation at New York University School of Law in 1975.
Those credentials set a clear course. Castleberry established himself in New York and built a long career in private practice. He served as a partner at Cooley Godward Kronish LLP. He worked on matters that drew on his advanced tax training as well as general corporate and transactional issues encountered by clients doing business in and through New York.
Colleagues describe him as methodical and exacting in approach. He favored careful analysis over flash. That temperament matched the work he did. Tax questions demand attention to detail. So do complex business arrangements. Over the years he handled a range of engagements where tax treatment, regulatory detail and negotiated agreements intersected.
Castleberry’s path reflects the arc of a mid-20th-century law career that remained relevant into the 21st century. He entered the profession at a time of shifting tax rules and evolving corporate structures. He kept his practice steady as rules changed and new issues arose. His education — from Arkansas to Harvard to NYU — supplied a mix of broad legal grounding and specialized technical study that shaped how he approached client problems.
Outside of case files and deal documents he remained tied to the professional rhythms of the New York bar. He maintained an office presence in the city and worked with colleagues across practice teams. He is licensed in New York and has spent his career serving clients there. He currently practices in New York, handling tax-related legal work.
