The people of Pennsylvania's 166th Legislative District first elected Greg Vitali to the House of Representatives in 1992. The first Democrat to win this seat, Vitali was re-elected to his ninth term in 2008.

Perhaps best known for his environmental advocacy, Vitali was the first Pennsylvania legislator to introduce climate change legislation (H.R. 200 of 2001). Vitali currently serves on the Pennsylvania Climate Change Advisory Committee.

Vitali has received the following environmental awards:

• 2009 PennFuture Green Power Hero
• 2008 PennEnvironment Environmental Champ
• 2002 PennFuture Green Power Policymaker Award
• 2000 Pennsylvania League of Conservation Voters' Hero Award
• 1997 Sierra Club Pennsylvania Chapter State Legislator of the Year
• 1995 Pennsylvania Wildlife Federation's Conservation Legislator of the Year

During his tenure in the legislature, Vitali has consistently been at the cutting edge of governmental reform issues. He has fought to ban legislative initiative grants, require competitive bidding of state bond contracts, require campaign finance data be accessible via the Internet, provide public financing for gubernatorial elections, ban tax dollars for public service announcements by legislators and the prohibition of legislative nonprofit corporations.

In 2007 he was appointed to the Speaker's Commission on Legislative Reform. In 1996 Vitali received the Common Cause of Pennsylvania Champion of Good Government Award.

In Harrisburg, Vitali serves on the House Appropriations Committee where he is Chairman of the Subcommittee on Fiscal Policy. He is also a member of the House Environmental Resources and Energy, Judiciary, State Government and Joint Legislative Air and Water Pollution Control and Conservation committees.

In his home district, Vitali was instrumental in Haverford Township's acquisition of the 209-acre Haverford State Hospital site and the preservation of large portions of that site for recreation and open space. He also secured state funding for the planning and construction of an indoor recreational facility there.

A world traveler, Vitali has toured Russia, China, Cuba, Vietnam, Israel, India and the Czech Republic as well as much of Western Europe. In 1983 Vitali rode his bicycle across the United States.

An avid distance runner, Vitali has completed 12 marathons including the 1980 Boston Marathon and the 2005 Prague International Marathon. He competes regularly in local foot races.

Vitali was born and raised in Haverford Township, Delaware County. He attended Sacred Heart Grade School and St. Joseph’s College Preparatory School. In 1978, he graduated cum laude from Villanova with a bachelor's degree in economics. Vitali earned his law degree from Villanova in 1981, and then opened his own law practice in Havertown where he worked for the next 11 years before his election to the state House. Vitali was adjunct faculty at Villanova University from 2000 to 2005.
