Our Firm
Our firm is built on a foundation of academic excellence, practical experience, and most importantly, hard work. We have lawyers at DeForest Koscelnik Yokitis & Berardinelli who are consistently recognized in The Best Lawyers in America and as Pennsylvania "Super Lawyers", honors received by only top attorneys based on the recommendations of their peers.

Our lawyers have a wealth of valuable legal experience and we complement each other well. Walter DeForest and Jackie Koscelnik formed the firm in Pittsburgh in 1994, following careers at Reed Smith Shaw & McClay. While continuing to represent a number of clients, Mr. DeForest and Ms. Koscelnik served, respectively, as outside general counsel and associate general counsel to Carnegie Mellon University from 1993 through 2002. George Yokitis and Mindy Shreve are nationally recognized litigators who previously headed the Pittsburgh office of Schnader Harrison Segal & Lewis from 1994 to 2001. David Berardinelli began his legal career at our firm after graduating Harvard Law School in 1996. Mr. Berardinelli served as a federal prosecutor in the Southern District of New York from 2000 to 2005, after which he returned to the firm and has become a partner who is well-seasoned in jury trials and white collar crime defense. In August 2012, Marie DeForest Garcia opened the firm's New York office after practicing with the litigation firm Conrad O'Brien in Philadelphia. Patricia Marley, who was previously General Counsel of Magee Womens Hospital from 1995 through 2006, is a well-versed health law attorney and actively represents clients in this area.

At DeForest Koscelnik Yokitis & Berardinelli, we believe that all clients are entitled to personal attention and outstanding service for reasonable fees. We pride ourselves on our diligence and accessibility and are generally available to our clients around the clock.
