  • Trevor Shipley Potts

    I've had the pleasure to work for attorney Kohnen as a law clerk before becoming a licensed attorney myself. I learned everything that I know from attorney Kohnen, from how to treat your clients with great compassion to how to present a winnable defense. There is no question that attorney Kohnen is one of the best criminal defense attorneys around, but more importantly, he is an outstanding human being. If my liberty interest were on the line, there is no one else I would trust more than attorney Kohnen in protecting my freedom and vindicating my rights. I highly recommend attorney Kohnen for anyone looking for top-notch criminal defense.
