Stephen Quirk, who has led Youth Emergency Services & Shelter for the past 10 years, last week resigned from his position as CEO, the organization confirmed. Quirk had been CEO of the Des Moines-based nonprofit since July 2008. Julie Schneider, chief advancement officer for YESS, has been appointed by the board as interim CEO; she has been with the organization for nearly 24 years. Travis Etchison, board president of YESS, said the search process for the organization’s next leader has begun. “Steve began his role at YESS over a decade ago and has grown the agency to what it is today – a leading youth services organization in Iowa,” Etchison said in an emailed statement. “It is now time for us to take this foundation and evolve further.” Founded in 1973, the nationally accredited child welfare agency is well-known for its annual YESS Duck Derby fundraising event. In its latest fiscal year ended June 30, the organization provided nearly 19,000 nights of care, a 12 percent increase over the previous fiscal year, and more than 5,000 hours of counseling.
