Chicago-based IPA 100 firm Grant Thornton (FY23 net revenue of $2.4 billion) has announced that after nearly 30 years with the firm, Seth Siegel has chosen to step down as CEO and transition to a senior advisor role.
Jim Peko, current COO of Grant Thornton Advisors LLC, has been appointed its CEO. According to Peko, “I thank Seth for all he has done to help transform Grant Thornton so adeptly for the future. He has been a colleague, mentor and friend to so many of us, and a tireless advocate for the firm’s best interests. As CEO, my priorities will focus on accelerating our current business strategy and solidifying our standing in the marketplace as a unique global platform, driven by quality, culture and differentiated capabilities.
Siegel shared, “With Grant Thornton poised for strong continued growth, I have made the decision that now is the right time for me to step down as CEO of Grant Thornton Advisors LLC and transition to a senior advisor role. Jim and I have worked closely together for many years, and he is the right leader for this new chapter — one who knows Grant Thornton well and has been integral to our many recent accomplishments and our quality-focused delivery.”
