Lawrence J. Waldman, chairman of the board of the Long Island Association and a veteran local accountant, will join a wealth management company in Jericho, starting next month, the company announced Tuesday.

Waldman, who will keep his LIA position, will serve as a managing director for the business, First Long Island Investors LLC, which was founded in 1983 and provides financial advice and money management services to wealthy clients.

Waldman, a Roslyn Heights resident, is leaving EisnerAmper LLP accountants, where he is an adviser. He is a former managing partner in the accounting firm KPMG’s Long Island office. He began his career at KPMG in 1972.

“This is a natural progression for me that builds on my career in public accounting, serving public and private companies across various industries, as well as my relationships with and knowledge of the Long Island business community,” Waldman said of his move to First Long Island. “This is a new challenge for me, and I’m excited about it.”

Robert D. Rosenthal, First Long Island’s chief executive, said the company had worked with Waldman from time to time to assist clients they had in common.

Rosenthal started First Long Island after spending 12 years as an executive for bakery manufacturer Entenmann’s Inc. of Bay Shore. He also was co-chief executive of the Islanders hockey team between 1992 and 1997.

In addition to his role at the LIA, the Island’s largest business group, Waldman sits on the board of trustees of the State University of New York. He was appointed board chairman of the Long Island Power Authority in the wake of superstorm Sandy in 2012 and held that post for 1 1⁄2 years. He also serves on the board of Bethpage Federal Credit Union and Melville-based Comtech Telecommunications Corp.

LIA president Kevin Law said Waldman “is a respected business leader who . . . helps support our efforts to grow Long Island’s economy, create jobs and improve the business climate.”
