    I highly recommend Zachary as a defense attorney. I hired him on a very serious jury case and the bottom line is we won. It is the best decision of my life at a critical point in my life. Zach was very professional, personable, a diligent expert, a masterful strategist but most importantly he took the time to understand my perspective. — Ronald C.

    I met Zack while I was representing a client in a high profile murder case in 2007. Zack represented a witness who was subpoenaed against his will. Although our interests were adverse, Zack was the consummate professional--calm and well versed in the relevant legal issues. He acted as an outstanding advocate for his client. I would recommend Zack to potential clients without hesitation. — Mark Bederow
