  • Odalo J. Ohiku

    Atty. Marquis is one of the most genuine, experienced, knowledgeable, and well-respected colleagues I have the pleasure of knowing. He is a fighter! He doesn't put up with non-sense in the courtroom and his skill and legal acumen are beyond reproach. I most highly endorse him.

    I endorse this lawyer. Have know Attorney Marquis for over 25 years. Have watched and learned from him over the course of my entire career. Often consult with him regarding trial issues. He always has valuable and spot-on advice to give. If you get a chance to watch him in trial do it. We should be able to get CLE credits for watching him in trial.
