  • Christopher E. Russell

    Casey is a Trial Lawyer with the leading Personal Injury law firm in Orange County, Aitken Aitken Cohn, and is ably taking the baton from the legend who established that firm, Wylie Aitken. The Aitken law firm sets the example for all others to follow as to how to give great service to their clients and get superior results. Casey is the President of the Orange County Trial Lawyers Association, which does terrific work in giving back to the community. We should all be as conscientious in doing good deeds and getting the results that Casey and the other good attorneys over at Aitken Aitken Cohn muster up on a daily basis. We attorneys would all have a better name within society if we all practiced law as do Casey and his firm. I unabashedly endorse Casey on this AVVO profile and recommend to anyone looking to hire a strong, honest attorney who obtains superior results to look no further than the good folks at Aitken Aitken Cohn and specifically Casey Johnson.
