Verified ClientHired Attorney 2021-2022Mark Wilson is one of the five most exceptional people I have known in my life. He is honest and a master of his craft. If you follow his advice, you will win!

Verified ClientHired Attorney 2019Mark Wilson is an honest, genuine, direct, efficient and passionate attorney. If he takes your case, you WILL have a positive outcome. His reputation alone is enough to bring the other side to the negotiating table, and that is what happened to us. I had a dispute with an attorney which I had tried to resolve directly with the attorney myself. The other attorney did not respond to my emails. I tried to take the other attorney to the Orange County Bar Association Mandatory Fee Arbitration. That was a joke! It was the proverbial Fox guarding the henhouse. Finally, I was lucky to find Mark Wilson, and I was lucky that he accepted my case. As soon as he filed a lawsuit against the other attorney, the other side came to the negotiating table and settled the case immediately. If it was not for Mark Wilson’s reputation, I know the other side would have dragged us through a long and lengthy process. I also would like to emphasize that Mr. Wilson is extremely passionate about his work, and that is what impressed me most about him. He is passionate about righting a wrong that has happened to a consumer as a result of his profession. He is doing the job that the California State Bar and the Orange County Bar Association should be doing, however, those entities do not have the power or motivation to discipline their members. Mr. Wilson is the answer to the problem of the dishonest and negligent attorney. He is very much results oriented. If he takes your case, do not think twice – you will be lucky to have him on your team.

Verified ClientHired Attorney 2018Mr. Wilson is a brilliant attorney who works very hard for his clients. He is informed, honest and a very compassionate individual. From my very first interview with Mr. Wilson I knew he was an Attorney who would indeed deliver. Mr. Wilson always made sure I understood every aspect of my case, from the possible outcomes to the overall process. From the very beginning Mr. Wilson kept me informed of options to take as well as the possible consequences thereof. His knowledge reaches far and is very diverse to say the least; there was never a turn that he did not anticipate. Mr. Wilson always answered all my questions knowledgeably and he always answered phone calls and emails immediately. Mr. Wilson brought my lawsuit to a very satisfying end and he was a blessing to my case.

Verified ClientHired Attorney 2017I highly recommend Mark Wilson as an attorney. Mr. Wilson is a masterful litigator. His acumen and presence in the courtroom is unparalleled. When a judge complements your attorney regarding the quality of his final argument, you know you are in good hands. Mr. Wilson was very informative and efficient throughout the process of the lawsuit. He handled our case to a successful conclusion. I hope I never have the need for an attorney in the future, but if I do I will be calling Mark Wilson
