Partners and trial lawyers Mark B. Wilson, P.C. and Michael S. LeBoff, P.C. possess decades of experience in the courtroom trying "bet the company" cases with millions of dollars at stake. Klein & Wilson represents both plaintiffs and defendants in business and commercial litigation matters, including contract, partnership, shareholder, real estate, and intellectual property disputes. Additionally, the firm represents injured clients in complex legal malpractice cases. The firm's partners are known for bringing persuasive arguments to life using state-of-the-art multimedia in every major case they try.
It is with sincere gratitude and the highest regard that I recommend Mr. Michael LeBoff.
After a deeply disappointing experience with a large and inefficient firm, finding Mr. LeBoff was nothing short of transformative. His practice reflects the very best qualities one hopes for in legal counsel—a boutique, refined, and highly professional approach where every detail is handled with care, precision, and discretion.
From the very beginning, he inspired confidence. He approached a complex matter with calm authority, absolute clarity, and a level of honesty that is both rare and invaluable. There were no unnecessary complications, no confusion—only thoughtful, strategic guidance delivered with integrity and purpose.
What truly sets Mr. LeBoff apart is not only his capability, but the sense of trust he creates. He has an exceptional ability to take what feels overwhelming and make it manageable, always ensuring that you feel supported, informed, and in control. His composure and professionalism remove stress from what would otherwise be a very difficult process.
In every respect, Mr. Michael LeBoff exemplifies excellence. For anyone seeking counsel they can genuinely rely on—someone capable, principled, and fully committed to achieving the best outcome—I cannot recommend him highly enough.

If you’ve been discouraged in your search for an honest and exceptional law firm, I’m grateful to share that there are still stellar firms you can truly trust. This team is professional, highly knowledgeable, and genuinely committed to advocating for their clients.

When I was in litigation, I felt cold like in winter. Mr. Mark Wilson is the warmth in the cold winter of stressful litigation. I have had the pleasure of working with Mr. Wilson and his team on a complex legal matter against mega law firms for six years, and I couldn't be more satisfied with their professionalism, ethics, experience, and strength.
Mr. Wilson is incredibly knowledgeable, detail-oriented, and result-driven. At every stage of my case, his ability to conduct thorough legal research, risk evaluation and anticipate potential issues, addressing them proactively, was particularly impressive. Mr. Wilson consistently went above and beyond to ensure the best possible outcome. His dedication and courage, combined with his strategic thinking and strong negotiation skills, led to a resolution that exceeded my expectations.
One of the standout aspects of my experience was the transparency and reasonableness of his firm's legal bill. There were no hidden fees or unexpected charges, throughout the process. Despite the complexity of my case against mega law firms, Mr. Wilson's legal fees were fair and aligned with the high quality of service provided. I am grateful that he has always demonstrated a genuine commitment to achieving the best possible outcome while being mindful of the financial impact during the past 6 years.
I highly recommend Mr. Mark Wilson and his team to anyone in need of legal assistance.

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.
