Awards & Recognition


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

We have been delighted with the excellent legal representation and prompt attention to our concerns which we have received from Lowey Dannenberg, a firm that quickly grasped our legal and business needs and expectations. Creative fee arrangements are welcome in a budget-conscious institutional environment. The bottom line is that Lowey Dannenberg consistently delivers superb results.

The quality of representation is not questioned here, especially for those attorneys, principally from Lowey Dannenberg, who worked so hard to achieve this creative and, in my experience, unprecedented global settlement.

~ Hon. Colleen McMahon, United States District Judge, S.D.N.Y.

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.

Lowey Dannenberg has worked tirelessly to promote harmony and efficiency in this sprawling litigation...[it] has done a superb job in its role as Liaison counsel, conducting itself with professionalism and efficiency….
