Arlington-based Nathan Associates Inc. names new CEO

Arlington-based consulting firm Nathan Associates Inc. said this week it has named Susan B. Chodakewitz CEO, effective April 27. Chodakewitz will replace Lakhbir Singh, Nathan’s current CEO, who is retiring after almost 39 years with the company.

Chodakewitz currently is president of another Arlington-based consulting firm, Tetra Tech AMT, and will serve as Nathan’s first CEO from outside the firm.

She has been president of Tetra Tech AMT since 2006 and is credited with more than doubling the company’s revenue by building its human resources and market position.  Tetra Tech is an international environmental and technical services consulting company, which last year, recorded $2.48 billion in revenue.

Chodakewitz began her consulting career with Booz, Allen & Hamilton. She then spent more than a decade at SAIC where she advanced to senior vice president, helping almost double revenue at the company's business consulting program. She also directed a SAIC unit that reached nearly $200 million in annual revenue.

Besides Arlington, Nathan and its subsidiaries have offices in Irvine, Calif., London and Chennai and Delhi, India. The firm, which has 192 employees, provides consulting and analysis in support of litigation, international development and trade, project financing, and numerous industries including gaming and telecommunications.
