As one of the top defense lawyers on the East Coast, William "Bill" Costopoulos has successfully handled some of the most infamous criminal cases in Pennsylvania history.
After serving briefly as a Dauphin County Assistant District Attorney, Costopoulos became one of the founding members of what would become Costopoulos, Foster & Fields Attorneys At Law, with its office located in Lemoyne, PA. He practices criminal law, criminal appeals, and personal injury litigation. His real talent, however, is his high-profile criminal defense work.
In 1992, for example, Costopoulos successfully appealed the case of Dr. Jay C. Smith, who had been convicted and sentenced to death on three counts of murder, prompting the state supreme court to overturn Smith's conviction and free him from death row. The case went on to be detailed in three books and a CBS-TV miniseries.
In 1994, Costopoulos defended Pennsylvania Supreme Court Justice Rolf Larsen in a historic Impeachment trial on the Pennsylvania Senate floor.
Costopoulos is perhaps best known, however, for his successful 2002 defense of York Mayor Charles Robertson, who was acquitted of murder charges stemming from the 1969 York race riots.
Recently, Costopoulos has defended the likes of Pennsylvania Senator Jane C. Orie and former state House Speaker H. William DeWeese on separate allegations of corruption.
The author of three novels and three nonfiction books, Costopoulos has taught trial advocacy as an adjunct professor at Dickinson School of Law and in 2003 was awarded the Widener University School of Law John Wherry, Jr. trial advocacy award. He continues to lecture on legal matters before bar associations, continuing legal education seminars and civic groups. In 2015, he received the Lifetime Achievement Award from the Legal Intelligencer for his impact and shaping of Pennsylvania's laws and positive contribution to the legal community.
Costopoulos received his Bachelor of Arts degree from Dickinson College and his Juris Doctorate, cum laude, from Duquesne University School of Law, where he was valedictorian and editor-in-chief of the law journal. He earned his Master of Laws degree from Harvard University School of Law.
