Verified ClientHired Law firm 2022-2025Before being introduced to Klein and Wilson, my wife and I had hired a large national law firm to represent us but it became clear that our case was not a top priority for that well-respected large law firm. As part of due diligence to find a new firm to represent us, we interviewed about 10 different lawyers. We selected Mark Wilson due to his communication skills, suggested approach to our case, and reasonable fees relative to LA-based lawyers. After Mark and his team quickly got up to speed on our case, they were always several steps ahead of the defendant’s litigation team. This proactiveness significantly contributed to the defendant settling the case versus being outlawyered in the court room with a risk of fraud charges. Most of my life, I have been the one pushing others to complete tasks and exceed expectations; however, I was able to take a back seat with Mark and his team driving the freight train toward the defendant. This reduced my anxiety and allowed my energy to be focused on what Mark and his team needed from me to move the case forward. Mark’s decades of experience combined with an energy level of people half his age is a lethal combination to have on your side of the table. And on top of that, he is a great guy that made what is typically an unpleasant process much more bearable, and oddly enough, sometimes fun.

Verified ClientHired Law firm 2022Our firm recently engaged Mark Wilson of Klein & Wilson to represent us in a pending legal complaint. Mark and his team are the complete package. They first analyzed our case in detail, built a legal strategy, conferred the strengths & weaknesses of the case and then gained our agreement on the direction. Once we agreed on the legal strategy, Mark jumped into action building our defense that led to a quick & successful settlement. Mark takes a fiduciary approach with remedies that are in their clients best financial interest, this was a welcomed change to our previous experiences. We highly recommend contacting Mark Wilson for your next legal escalation. Greenco Depot Aliso Viejo, CA
