David Keller Trevaskis, Esquire, is an attorney and former third grade teacher with a Master’s Degree in Education.   Trevaskis is the Pro Bono Coordinator for Legal Services for the Pennsylvania Bar Association (PBA), responsible for assisting local bar associations, legal services programs and other groups who offer pro bono legal services across the Commonwealth to help improve the access to justice for the neediest among us.  Trevaskis is involved in numerous clinics and other activities that provide support for those with legal needs.

Trevaskis has long been a champion of non-violence, having been the designer of and original trainer for Project PEACE (Peaceful Endings through Authorities, Children and Educators), a peer mediation, anti-bullying and youth court program jointly sponsored by the PBA and the Pennsylvania Office of the Attorney General.  A co-author of the 2018 updated text, School Law: Legal Framework, Guiding Principles, and Litigated Areas, David is an expert on school law and school crisis. Trevaskis has contributed chapters on bullying and the law, law review articles on youth court and breaking the school to prison pipeline, and pieces on civic education among his other writings.  He teaches in the classroom and online at Community College of Philadelphia, Gratz College, Arcadia University and the University of New England.  He was an instructor with Bob Randall Associates for nearly three decades and treasures his memory of everyone associated with those classes.

Trevaskis has won more awards than any one man deserves, but he wants you to know he was given the Isadore Starr Award in 2015.  Dr. Starr, a lawyer/educator who just passed away in February 2018 at the age of 106 years young, personally saluted David when David was given his award and that made it even more special.

Trevaskis is married with two children and two grandsons.  Below Trevaskis is seen conducting a mock Supreme Court hearing with middle school students, using a hypothetical case inspired by current cases before the Court.
