About William

William A. Slayne is a Managing Director and Wealth Partner at J.P. Morgan Wealth Management.

Bill develops enduring relationships with wealthy individuals and families, helping them discern what they want to achieve with their wealth and pursue those goals through focused attention and tailored advice. He offers the character and consistency to support clients in advancing meaningful objectives, providing them with greater ease and reliability in managing their financial affairs.

Bill views each client relationship as a partnership that requires ongoing communication, collaboration, and active engagement. He emphasizes that his approach is about solving problems, simplifying complexity, and educating multiple generations. "Client care is what we're all about," he notes.

Bill developed his investment acumen in part at U.S. Trust, where he was a Senior Vice President and Senior Portfolio Manager. He began his career in 1988 as a Senior Trust and Estate Officer with Chemical Bank after earning his B.A. from the University of Delaware.

Bill lives in Saddle River, New Jersey, with his wife, Tracy. They have three adult daughters. Bill has been a long-time volunteer with the Saddle River Fire Department.
