Pennsylvania’s 67 counties provide services that positively impact the daily lives of our families and help our communities.
Commissioners, elected county executives, county councils, chief clerks, solicitors and many others are dedicated to enhancing the quality of life for their county's residents.
Among the critical, wide-ranging functions are: judicial administration, corrections and justice related activities, community and economic development, environmental planning, public health and safety, human services (including children and youth, mental health, intellectual disabilities and drug and alcohol), emergency management, elections and real estate tax assessment.
