  • Andy Simrin

    I've known attorney Robert Callahan since I was a law student interning at the district attorney's office in 1990. I actually prosecuted a case against a defendant who was represented Mr. Callahan. More accurately, I should say I attempted to prosecute the case. After Mr. Callahan's clear and compelling trial presentation, it took the jury only minutes to arrive at its verdict of not guilty. I was convinced myself, and I told Mr. Callahan that if I had been on the jury, I would have joined the rest of the jury and voted not guilty. Robert Callahan is a compassionate, confident and compelling advocate as a trial level criminal defense and civil litigation attorney.

    Robert is a brilliant attorney. I have seen him in action in trial as well as consulting with clients and colleagues. He commands respect from judges, juries, and his peers. He is also a compassionate and generous person.
