Patrick K. Nightingale is a practicing criminal defense attorney in both state and federal court in Southwestern Pennsylvania.

He began his legal career as a prosecutor with the Allegheny County District Attorney’s Office in 1996. In 1999 he helped to found the Domestic Violence Prosecution Unit. Since 2002 Mr. Nightingale has specialized in criminal defense with a particular focus on protecting the rights of cannabis consumers.

In October, 2009, Mr. Nightingale re-established the Pittsburgh NORML chapter after the introduction of PA’s first medical cannabis bill. Since then he has spoken extensively on the subject of cannabis reform. Mr. Nightingale has been a frequent guest on local radio and television, and is a trusted voice on reform related questions. He has also been privileged to testify on numerous occasions before Pennsylvania legislative bodies considering medicinal cannabis legislation.

In 2015 Mr. Nightingale joined the Pennsylvania Medical Cannabis Society and now serves as Executive Director. “I was very excited to join a non-profit with a mission of both advocating for patient interests and promoting industry best practices. As we move forward with implementing Act 16 I am convinced that these interests are aligned. Simply stated, if Pennsylvania patients do not participate in the program, either because the medical cannabis products are too expensive or because of inferior quality, the program will necessarily fail”

Mr. Nightingale is married to fellow activist Theresa and they have three children together – Perrin, Mac and Xavina.
