Jeffrey M. Weiner joined Marcum in 1981 and has served as Managing Partner since 1990. Under his leadership, Marcum has expanded from a one-office regional firm of 20 employees to a firm ranked among the largest in the United States.

Mr. Weiner has been single-minded in diversifying Marcum's services and capabilities to meet the evolving needs of the Firm's clients, a key factor in the Firm's continuing growth. In addition to the core tax and accounting business, Mr. Weiner has built a multiservice organization providing a comprehensive range of professional services, including accounting and advisory, technology solutions, wealth management, and executive and professional recruiting. The Marcum Group companies include Marcum LLP; Marcum Technology LLC; Marcum Search LLC; Marcum Financial Services LLC; and Marcum Bernstein & Pinchuk LLP.

Mr. Weiner has also steadily expanded the Firm's global footprint through strategic mergers and acquisitions in major business markets across the country and overseas. Today, Marcum LLP is one of the largest independent public accounting and advisory services firms in the nation, with offices throughout the U.S., Grand Cayman and China. Headquartered in New York City, Marcum provides a full spectrum of traditional tax, accounting and assurance services; advisory, valuation and litigation support; and an extensive range of specialty and niche industry practices. The Firm serves both privately held and publicly traded companies, as well as high net worth individuals, private equity and hedge funds, with a focus on middle-market companies and closely held family businesses.

Mr. Weiner is frequently singled out for his leadership role in the accounting industry. In 2013, he was voted one of the industry's Top Five Most Admired Peers in a national poll by Inside Public Accounting. The previous year, he was an inaugural honoree in Accounting Today's Managing Partner Elite Class of 2012. The publication recognized Mr. Weiner for his "national drive" in growing Marcum from a regional firm to a national leader. "Few managing partners can boast growth like that, and even fewer could successfully manage the resulting complexity: Weiner's discipline and vision make all the difference," the editors wrote. Accounting Today also recognized Mr. Weiner in 2010 as one of the industry's Top 100 Most Influential People, alongside many other key influencers.

In addition to his responsibilities as Managing Partner, Mr. Weiner manages Marcum's entertainment practice and is a nationally recognized expert on personal business management for the entertainment industry. Mr. Weiner served as Executive Producer of the Universal Pictures films, The Bourne Supremacy and The Bourne Ultimatum, starring Matt Damon and released in July 2004 and August 2007, respectively. He was Executive Producer of The Hades Factor, a mini-series that aired on CBS television in April 2006, and a Producer of The Bourne Legacy, released by Universal Pictures in August 2012, starring Jeremy Renner. He is currently co-producing the fifth installment of the Jason Bourne franchise, with Matt Damon back in the title role, due out in July 2016.

Mr. Weiner is a founding member of the LEA Global: Leading Edge Alliance, an international association of independent accounting firms. In 2013 and 2015, LEA honored Marcum with Edge Awards for industry excellence in four categories, including Mr. Weiner's blog, Thoughts of the Week. Marcum was also the recipient of the 2012 LEA Innovative Firm Initiative of the Year Award, for the first annual Marcum MicroCap Conference, the first event of its kind in the accounting industry. In 2009, the association distinguished Mr. Weiner with the LEA On the Edge Innovation Award, which recognizes an individual who has made an enduring and pioneering contribution to the public accounting profession.
