When Steven J. Moore and some other partners in the Stamford office of Kelley Drye & Warren wanted to make a move, Moore called a former classmate from the University of Connecticut School of Law. The classmate, Louis R. Piscatelli, happens to be a Connecticut-based regional senior partner at Withers Bergman, a London-headquartered firm known for its trust and estate planning, tax work and other legal services for high net-worth individuals.

Not only was he “getting a call from an old friend,” Piscatelli said, but the intellectual property, corporate finance, public company and commercial practice areas that Moore’s group would bring from Kelley Drye would help Withers meet its strategic goal of expanding its capacity in those practice areas.
