About David

Founder and Principal of ZELLIS LAW, LLC


David Zellis has spent his entire 30 year career working in the criminal justice system.  

After graduating with a Bachelor’s Degree from the University of Michigan, David went on to receive his Doctor of Law Degree from Emory University School of Law.

David’s first job after law school was as an Assistant District Attorney in the Bucks County District Attorney’s Office.  During his tenure as a prosecutor, David rose through the ranks of the District Attorney’s Office until he was appointed as the First Assistant  District Attorney (2nd in command of the office).  As a prosecutor, David convicted murderers, rapists, armed robbers, drug dealers and handled thousands of DUI cases.  David was also instrumental in starting up the Bucks County Drug Court.

David's most celebrated case was the infamous “church lady murderer”. The investigation and the prosecution drew national attention and was the subject of an hour long Dateline NBC as well as the Investigation Discovery channel's  shows entitled, "True Crimes with Aphrodite Jones", "Solved", "Snapped" and "Nightmare Next Door".

After leaving the District Attorney's Office, David founded Zellis Law, LLC, a law firm which focuses on criminal defense and “solutions for your legal issues”.


"In all of my years of practicing law, the common theme in my

career has been helping people in their time of need.  I have

been blessed with the ability to assist so many people.  To a

large extent, I truly believe that a lawyer is like a doctor in so

far as someone presents me with a legal problem and I need

to fix it or mitigate the damage."


Previously, David co-authored a chapter entitled “Legal Issues and  Autism Spectrum Disorder” in the recently published book, Autism Spectrum Disorders in Adolescents and Adults.

David has appeared as a legal expert in the Legal Intelligencer, the oldest law journal in the United States, The New York Times, Bloomberg Radio and the Philadelphia Inquirer.

David's Philosophy

All criminal charges, whether a DUI or a violent crime, bring an inordinate amount of stress to you and your family. A criminal conviction can ruin your reputation, job opportunities, and relationships with family and friends. Additionally, if the government convicts you of any crime, you generally are at risk for at least some term of incarceration. As a result, one of the most important decisions that you must make is choosing the right criminal defense attorney to represent you.
