Known by the people of Chester County simply as “Andy,” Senator Andrew E. Dinniman is recognized as a leader in education and an advocate for communities and families through three decades in public service.

That vision and leadership led to his 2006 election and reelection in 2008 and 2012 to the Pennsylvania Senate, representing Pennsylvania’s 19th District.

Prior to serving in the legislature, Senator Dinniman served for 15 years as a Chester County Commissioner, making him the longest-serving commissioner in county history. As Commissioner, Andy demonstrated a true commitment to the future of Chester County by taking on some of the region’s most difficult issues. He worked to found the Safe Harbor Homeless Shelter, the Chester County Gleaning Project and served as one of the principal architects of Landscapes, the county’s award-winning open space plan. Both as a commissioner and a state senator, Andy also has consistently opposed tax hikes and increases in spending.

Before being elected county commissioner in 1991, Senator Dinniman served on the Downingtown Area School Board and the West Whiteland Municipal Authority. A teacher, West Chester University professor and community leader, he has been honored by numerous education, business, environmental, veterans’ and service groups: Temple University’s College of Education, Pennsylvania Bio, the French and Pickering Creeks Conservation Trust, the Congressional Medal of Honor Society, the YMCA of the Brandywine Valley and the ARC of Pennsylvania.

In the Senate, his priorities include access to education, economic security and job growth, local government control over local issues, environmental protection, historic preservation, and quality-of-life issues.

Senator Dinniman serves as minority chairman of the Education Committee and is a member of the Agriculture and Rural Affairs, Environmental Resources and Energy, Public Health and Welfare and State Government committees.

Senator Dinniman is also a member of the Ben Franklin Technology Development Authority and the Joint Legislative Air and Water Pollution Control and Conservation Committee.

He also serves on the Education Commission of the States, the Pennsylvania State Board of Education, the Pennsylvania State Public School Building Authority, the Pennsylvania Higher Educational Facilities Authority, and the Pennsylvania Wing of the Civil Air Patrol.

In addition, Senator Dinniman belongs to the BIGS (Big Brothers and Big Sisters) Caucus, the Brain Injury Caucus, the Community College Caucus, the Diabetes Caucus, the Early Childhood Education Caucus, Fire and Emergency Services Caucus, the International Commerce Caucus, the Joint House and Senate Autism Caucus, the Legislative Hunger Caucus, the Life Science and Biotechnology Caucus, the Nonprofit Charitable Caucus, the YMCA Legislative Caucus and the Muhlenberg German-American Caucus.
