The team built for the hardest cases.

Cavaliere & Mangiaracina is a Pennsylvania and New Jersey trial firm built for the cases other firms turn away: catastrophic injuries, medical malpractice, and cases where people were harmed by exposure to dangerous chemicals, all won or lost on the medicine, the engineering, and the proof. Two founding trial lawyers try these cases to verdict, with an in-house physician reading the medicine and an in-house scientist building the evidence, on staff and on your file from the first day. Our pledge is plain. Put the sharpest medical, scientific, and legal minds in your corner, do the hardest work early, and prepare your case to be won in front of a jury. If you have been seriously hurt, you do not need to understand the law today. You need people who already do, and who will tell you honestly whether you have a case.

How a case gets made

The power of a case is the information behind it.

We read the decisions that govern Pennsylvania injury law and trace how they cite one another, and we keep that record as a working map. The picture below is part of it: 1,976 Pennsylvania decisions, connected by 9,876 citations, drawn from the public record.

A case is built from what the firm can prove, and proof begins with knowing the law that governs it. Before we write a claim, we check the authorities it rests on against the record itself. The map is one of the tools we built in-house to do that work.

The firm’s map of Pennsylvania injury law.

The firm’s map of Pennsylvania injury law. Each dot is a court decision; each line is one decision citing another. 1,976 decisions and 9,876 citations, built around thirty Pennsylvania rulings the firm has researched, coloured by practice area.

Larger dots have been cited more often; colour is the practice area a decision reached us through, not a legal classification.
