NEW YORK CITY—Frank Longobardi on Thursday took the reins as CohnReznick's CEO, having been elected to the role by the firm's partnership this past May.Longobardi was elevated to the top spot after serving as regional managing partner—New England for the New York City-based accounting, tax and advisory firm, created by the 2012 merger of J.H. Cohn and Reznick Group.

Longobardi has also served as a member of CohnReznick's go-to market committee, which oversaw the strategic planning for industry and service specialization post-merger. Prior to that, Longobardi was responsible for all of J.H. Cohn's industry groups, standardizing to the marketing, leadership development and continuing education efforts of each practice. His own company, Haggett Longobardi, combined with J.H. Cohn in 2007.

CohnReznick's former co-CEOs, Ken Baggett and Tom Marino, are stepping down pursuant to the terms of the partnership agreement. Baggett began his tenure as the firm's first chairman of the board on Thursday, while Marino remains a member of the executive board through May 2016, when he will retire.

“CohnReznick has grown significantly over the past years, thanks to Ken and Tom's vision and guidance, and I am confident that we will continue on this trajectory with great success ahead,” Longobardi says. “As CEO, I plan to move the firm forward even more, working with my colleagues to create remarkable results for our clients, developing future leaders of the firm, and leading significant growth and cultural initiatives.”

Longobardi and the executive board have appointed several partners to leadership positions within the firm. They plan to announce the appointments this coming Monday.
