~  Hon. Cynthia Rufe

United States District Judge, E.D. Pa.

"I note that at the end of Richard Cohen’s papers are his law firm’s resume and quotes the approval of various of my state and federal colleagues for the work of the Lowey Dannenberg Cohen & Hart firm. I will join in that chorus…claims in this case were complex, they required participation of highly skilled and specialized attorneys and all the firms involved worked with great effort to prosecute their claims and defenses efficiently and effectively."

~  Hon. Timothy S. Driscoll

N.Y. Supreme Court Justice, Nassau County

"I commend the plaintiffs for the work they did in this case and for having...diligently prosecuted it. [This case] would have been basically an orphan, or a case that no one would have brought had Richard Cohen not brought it. You produced what appears to be a substantial result for your clients."

~  Hon. Stephen P. Lamb

Vice Chancellor, Delaware Chancery Court, New Castle County
