New York City, NY – Marcum LLP today announced that it has joined forces with Castellano, Korenberg & Company, effective August 1. The Hicksville, New York, CPA firm adds six partners and 27 associates to Marcum’s Melville, Long Island, office.

Founded in 1991, the Castellano, Korenberg team focuses on accounting and advisory services to the construction industry – a specialization that complements Marcum’s leadership as a national construction industry service provider. The firm offered a full range of accounting, auditing, tax planning and compliance, and consulting services to general and specialized contractors. It also served clients in related industries including transportation, communication, manufacturing/distribution, and real estate.

Daniel A. Castellano, CPA, CK’s managing partner, and Neal Korenberg, CPA, both join as Marcum partners. Mr. Castellano also will serve as Long Island leader for the Firm’s national Construction Services group.

“Dan Castellano and Neal Korenberg built a very successful specialty firm that was recognized and respected throughout the Long Island region. They and their team will be tremendous assets in our national construction industry practice while further strengthening our position as Long Island’s largest accounting and advisory services firm. I have known both of them almost my entire professional career and am proud at this point to be able to be their partner,” said Jeffrey M. Weiner, Marcum’s chairman & chief executive officer.

“The opportunity to join Marcum gives us critical mass, additional expertise in our keystone industry, and access to a national service portfolio that will significantly expand how we serve our clients. This is a great step for our clients as well as our professionals, and we are tremendously excited about the future as a part of Marcum,” Mr. Castellano said.

Carolyn Mazzenga, Marcum’s Melville office managing partner, said, “The Castellano group is a great addition to our region. Their focus on construction and related industries is extremely well suited to the Long Island region and will expand our other industry strengths in this market.”

“Marcum is very fortunate to welcome a team of the caliber and experience that Castellano, Korenberg brings to our construction group,” said Joseph Natarelli, Marcum’s national construction industry leader. “We look forward to collaborating with them as we continue to expand our practice nationally and regionally.”
