Commissioner Diana Irey Vaughan, Chair

Diana Irey Vaughan

Diana Irey Vaughan, elected in 1995, is the longest serving Commissioner, now serving her seventh term of office, and is the only woman to have ever served in Washington County.

Diana is a leader in economic development, establishing a public-private partnership in 1999 with the Washington County Chamber of Commerce, to develop a “one-stop shop” creating a unified delivery system for economic development efforts. She has been instrumental in the progress of Starpointe Business Park and California Technology Park, and played a key role in the development of Southpointe I and II, having co-chaired the Western Center Land Reuse Task Force.
Through her insistence on long-range planning, low tax rate, and a unified economic delivery plan, Diana has helped to foster an environment that brought more than 6,000 new jobs, ranking Washington County third in the nation in job growth by U.S. Department of Labor in 2010.

As a mother, Diana recognizes a crucial part of county government is the service rendered to children and youth. She has been outspoken in her quest to ensure that services are delivered in a competent and caring manner. Because of her passion for these matters, she has served on the County Commissioners Association of Pennsylvania Human Services Committee and on the National Association of Counties’ Human Services and Education Committee. In 2011, she formed the Washington County Children and Youth Task Force with members of CYS, courts representatives, local legislators, law enforcement and local child protection services, in an effort to improve services for child and youth in Washington County.

Personal Life

Diana is the mother of three adult children and is married to Colonel Robert Vaughan, who has served in seven mobilization with the U.S. Army Reserves. In 2012, Diana launched her own business, SucSeed, which offers a curriculum designed to help other women succeed. Diana volunteers her time in the Washington County Correctional Facility working with female inmates in a re-entry program. The program is designed to prepare incarcerate individuals for success when released back into society.


Most recently, she was the recipient of the 2014 Athena Award by the Washington County Chamber of Commerce, 2017 Mon Valley Hospital Gibbons Award for Dimensions in Community Service, and 2017 World Class CEO by the Southpointe CEO Association.
