Judicial Praise:

From Judge Madeline Cox Arleo, of the U.S. District Court for the District of New Jersey:

I just want to thank you for an outstanding presentation. I don’t say that lightly . . . it’s not lost on me at all when lawyers come very, very prepared. And really, your clients should be very proud to have such fine lawyering. I don’t see lawyering like this every day in the federal courts, and I am very grateful. And I appreciate the time and the effort you put in, not only to the merits, but the respect you’ve shown for each other, the respect you’ve shown for the Court, the staff, and the time constraints. And as I tell my law clerks all the time, good lawyers don’t fight, good lawyers advocate. And I really appreciate that more than I can express.
