About Brennan Law Offices

The Story Behind Our Philadelphia Criminal Defense Firm

Plenty of attorneys can defend a criminal case. Far fewer earn the right to be called a Philadelphia lawyer.

That distinction matters to us. It reflects something we work to live up to on every case we take, whether it's a first-time DUI or a federal matter with a client's entire future on the line, and it starts with a phrase whose meaning goes back further than most people realize.

No Matter Where You Live, You Need a Philadelphia Lawyer.

Where the Phrase "Philadelphia Lawyer" Comes From, and Why It Matters for Your Defense

If you've heard the term "Philadelphia lawyer" before, you've probably heard it used as a compliment, and a specific one. It doesn't just mean an attorney who happens to practice in this city. It's shorthand for something sharper: an advocate known for brilliance, tenacity, and a refusal to back down, even when the case looks impossible.

The Case That Helped Define the “Philadelphia Lawyer”

The phrase traces back to 1735, to a Philadelphia attorney named Andrew Hamilton and a case that had no business ending in his client's favor. Hamilton was defending a printer named John Peter Zenger, who'd been jailed for publishing criticism of a colonial governor. Under the law at the time, the truth of what Zenger printed didn't matter. Criticism itself was the crime. Hamilton argued anyway that truth should be a defense, and the jury agreed, acquitting Zenger in a case the law said he should have lost.

The case helped establish Philadelphia’s reputation for lawyers who look beyond the apparent limits of an argument and find a way to advocate for their clients, even when the odds seem firmly stacked against them.

Putting Your Defense in the Hands of a Philadelphia Lawyer

That longstanding legacy is the same reputation we hold ourselves to today, not because of where our office happens to be located, but because of what that history represents: a willingness to fight for a client even when the outcome looks decided in advance. This is the standard behind every case William J. Brennan takes on, whether for a client in Philadelphia or a client calling from somewhere else entirely.

A Brief Introduction to William J. Brennan

William J. Brennan has spent nearly 40 years as a criminal defense attorney, but the reason he does this work hasn't changed much over that time. He believes people facing criminal charges deserve someone in their corner who won't judge them, won't assume the worst, and won't back down just because a case is difficult or unpopular.

That belief has taken him from local courtrooms to matters that drew national attention, including cases with political stakes reaching all the way to a presidential impeachment. Through all of it, his approach has stayed the same: understand the case, understand the person behind it, and fight for both with everything he has.

No Judgment, No Agenda: What We Believe

Brennan Law Offices was built around a simple idea: the fight you get shouldn't depend on who you are, what you're accused of, or who's paying attention.

That means we don't screen clients based on politics, public opinion, or the nature of the charge. We've represented people across the political spectrum and made a point of never being defined by any one of them. We've represented clients in cases that made headlines and clients whose names never appeared in a single article, and we've given each one the same commitment. Not every tragedy is a crime, and not every person accused of a criminal offense is guilty. We believe every client deserves both empathy and a fierce advocate, and we don't think those two things are in conflict.

We also believe in fighting to win, not billing to profit. A career built on hundreds of cases isn't built by taking only the easy ones. It's built by taking the cases where the accused needs someone willing to fight for them, and doing that work with the same intensity every time.
