Patrick Hagerty, Gray Ritter Graham Photo

"For me, being a lawyer has always meant being a litigator. Trial by jury is enshrined in the Constitution, and the courtroom is one of the very few places ordinary citizens can stand on equal footing with giant corporations. Clients always appreciate someone standing up in court for them, telling their story to the judge, the jury and the public."
