What distinguishes your law firm from others?

"But there is one way in this country in which all men are created equal-there is one human institution that makes a pauper the equal of a Rockefeller, the stupid man the equal of an Einstein, and the ignorant man the equal of any college president. That institution, gentlemen, is a court. It can be the Supreme Court of the United State or the humblest J.P. court in the land, or this honorable court which you serve. Our courts have their faults, as does any human institution, but in this country our courts are the great levelers, and in our courts all men are created equal." Atticus Finch Harper Lee, To Kill a Mockingbird 218 (1960)

"I consider trial by jury as the only anchor ever yet imagined by man, by which a government can be held to the principles of its constitution." Thomas Jefferson (1788)
