“I’ve been a judge, as you know, either in state or federal court, for over 26 years, and you get a feel for  the quality of representation before you. But more than that, the quality of the people, personally and professionally. And  the gentlemen who are here in the courtroom,  Ramzi [Abadou], exhibited such professionalism and such hard work and such good faith in pursuing this.”
Similarly in Tripp, et al. v. IndyMac Bancorp, Inc., et al., Case No. 2L07-CV-1635-GW (VBK) (January 28, 2013), the Hon. George H. Wu stated in reference to Mr. Abadou that:
“Counsel actively, thoroughly and impressively litigated a complex subject matter (both factually and legally), all the while confronting formidable defense counsel. Obviously, the plaintiff class did not face a simple path if it continued with this litigation into further discovery, summary judgment motions and, eventually, trials and, potentially appeals. Counsel has obtained a not insubstantial settlement figure as the result of their hard, and capable, work.”
Mr. Abadou attended Pitzer College where he earned a B.A. in Pan-African Studies in 1994 and later obtained an M.A. in political science from Columbia University in 1997. He received his J.D. from Boston College Law School in 2002.
