    It had been great working with the firm, and Mark and Eric helped me navigate a potentially very distressing situation with ease and confidence. I have 100% trust in them that they will guide me towards the path that is to my desire and benefit. We’ll definitely work with them again!

    Before 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.

    Mark Wilson is the best attorney I have ever worked with. Mark and his team were extremely professional and empathetic in their approach to our situation. They are very efficient with their time and extremely knowledgeable. One of the most impressive things to me was the fact that they provided a budget after initially reviewing our case, and in the end they spent a few dollars less that they had budgeted. That HAS NEVER HAPPEN in all the years I have dealt with a number of attorney’s!! Our case centered on a fee dispute with another law firm, and was resolved to our satisfaction. I would highly recommend Mark and his team to anyone.

    In my experience, the attorneys at Klein & Wilson are tough, focused and dedicated to their clients, in counsel and in the courtroom. Mark and everyone I’ve had the pleasure of speaking with at K&W have been patient, communicative and very clear with me about their strategy for success. They listen to my ideas, answer all my questions and carefully consider all options. When looking for a serious litigation attorney, I learned of their very high win rate. They have demonstrated to me that they have a sound moral compass and the tenacity to go the distance. They are fair but they don’t back down. I’ve been impressed from the start and am pleased to recommend K&W.
