Towers Watson COO to Retire by Year's End

Mactas, 58, has been with the company for 31 years. He served as Towers Perrin Chief Executive Officer before stepping into the role of Towers Watson president and COO after the merger of Towers Perrin and Watson Wyatt Worldwide in 2010.

“Mark has established a reputation as a leader who operates with unquestionable integrity and throughout his career has been a role model for the company’s values,” said John Haley, Towers Watson chairman and chief executive officer.

In the coming months, Mactas will continue in his current role. The company said he will continue to position Towers Watson for growth through his input into overall strategy, furthering the company’s integration efforts, and providing guidance in critical areas such as leadership development and succession planning.
