BDO USA Announces New Board Chair

Chicago-based IPA 100 firm BDO USA (FY23 net revenue of $2.9 billion) has announced the board’s election of Natalie Kotlyar to her inaugural term as chair of the board of directors. Kotlyar has served on the board since November 2020 and was re-elected to a new term this year.

Kotlyar succeeds Kelly Johnson, who served as BDO’s first female board chair since 2019. In addition, Kirstie Tiernan was elected as a new board member and John Marquardt was elected to a second term. The board also extended the term of Tony Argiz through the remainder of the term of Mark Ellenbogen’s vacated board seat. Ellenbogen will roll off the board when he assumes the role of COO. All changes are effective July 1.

“I’m delighted to extend my sincere congratulations to Natalie on her election as board chair,” said Wayne Berson, CEO of BDO USA. “Her legacy of leadership, unwavering commitment to sustainable growth and extensive understanding of our client service approach make Natalie an invaluable choice for leading BDO into its next chapter. I’d also like to thank Kelly for her service and steady leadership.”

Kotlyar has served as an advisor to BDO clients for over 25 years. She has held various leadership positions within BDO, most recently leading the firm’s industry group program and managing the program to enhance relationship and account management with the firm’s priority clients. Additionally, she acts as BDO’s country coordinator for Israel and Eastern Europe.

Tiernan’s addition comes at a pivotal time for the firm, as she has been instrumental in developing BDO’s data and artificial intelligence (AI) practice and spearheads client-facing AI initiatives. Tiernan is the national go-to-market leader in BDO Digital and leads the labs practice.
