Carl E. Clark II
President and Chief Executive Officer

Carl E. Clark II is the President and CEO of Devereux Advanced Behavioral Health, and only the seventh president in the organization’s history, since our founder Helena T. Devereux resigned from the position in 1957.

Prior to joining Devereux as senior vice president and chief operating officer in 2015, Clark developed a national reputation as one of the top operational and leadership experts in the nonprofit arena. 

For more than 20 years, he served in a variety of leadership roles at NHS Human Services, including regional executive director, senior vice president of program operations and, ultimately, executive vice president.

Before his work at NHS, he served as special assistant to the executive deputy secretary for the Pennsylvania Department of Public Welfare. Clark’s early professional years were spent in direct care of children with special needs and those with juvenile justice involvement.

Clark holds a Bachelor of Arts in Administration of Justice from Penn State University and a Master of Science in Public Administration from Shippensburg University.

He serves on the boards of the Rehabilitation and Community Providers Association (RCPA), the Robert K. Greenleaf Center for Servant Leadership® and the Youth Services Alliance of Pennsylvania.
