Our mission is to help you prevail. We get results.

We know the courtroom and how to win. We also know how to keep you out of the courtroom if it's in your best interest.

For over 20 years, DeForest Koscelnik Yokitis & Berardinelli has built a reputation as one of the hardest working firms in Pittsburgh. With offices also in New York and Detroit, our work goes far beyond Pittsburgh as clients nationwide seek our representation.

Our firm has a collaborative spirit and our lawyers work together efficiently and cost-effectively to advise and defend clients in federal and state courts and before administrative tribunals.

We're focused, diligent, and accessible. We measure our success in the value we add to a matter and the longevity and depth of our relationships with our clients.
