PHOENIX — The Goldwater Institute in Phoenix has lost its top staffer

Institute spokeswoman Starlee Coleman says CEO Darcy Olsen has left the conservative think tank after 16 years at the helm, The Arizona Capitol Times reports (http://bit.ly/2uaUq4A).

Olsen cites family needs for leaving the Goldwater Institute. Olsen is a foster mother who has adopted three infants who have stayed in her home.

Olsen is the second high-profile departure from the Goldwater Institute in as many years. Clint Bolick, formerly the institute’s lead attorney, was appointed to the Arizona Supreme Court in 2016.

Victor Riches, a former deputy chief of staff to Gov. Doug Ducey and the president of the Goldwater Institute since 2016, will assume the duties of CEO.
