Expert Guidance for Independent Fund Directors

David Leahy provided exceptional counsel to our board during a complex regulatory review of our closed-end fund. His 45 years of experience, particularly his deep knowledge of securities regulation and mutual funds law, was immediately evident. He has a remarkable ability to distill complex SEC requirements into actionable advice for independent directors. His background from Sullivan & Worcester and his recognition in corporate law gave our entire board immense confidence. The one area where we experienced slight delays was in receiving draft documents, as his schedule is clearly in high demand. However, when we did meet, his preparation and strategic insight were unparalleled. For any fund board navigating governance or regulatory challenges, David’s blend of academic pedigree and practical wisdom is a tremendous asset.
