It’s been a big year for venerable Wilmington Trust, having merged with M&T Bank Corp. Though the old name has all but disappeared, its investment wing continues. As vice president and trust counsel, Mary B. Hickok helps to ensure its commitment to customers, as she has since she joined the bank in 1988. Those years of collaboration with clients on estate planning translate well to her work for the Delaware Community Foundation, where she serves on committees for planned giving, grants and professional advisers. At Wilmington Trust, she is a resource to the wealth advisory staff and to attorneys across the country.
