-- Abraham Lincoln

Mark Brown has a reputation as a really good lawyer. That’s one reason that for more than 20 years he has successfully represented some of the largest corporations in the nation. It’s why jurors ask for his business card after seeing him in trial. It’s why he has recovered and saved tens of millions of dollars for his clients. It’s why peer reviews from judges and other attorneys earned him the coveted “AV (Preeminent)” rating from Martindale-Hubbell, reserved for those lawyers who demonstrate the “highest level of professional excellence."

But even more importantly, Mark has a reputation as a really good person. His genuine compassion for and dedication to his clients are obvious from the first meeting, and the respect he earns from judges, juries, and even opposing counsel helps his clients receive the best possible results, at the earliest possible time, and without unnecessary expense or added conflict.



As a talented trial lawyer, Mark Brown understands what is important to judges and juries, and every step he takes is carefully chosen with trial in mind. By focusing on what really matters and ignoring the ‘noise’ that other lawyers often create, Mark can better see the whole chessboard.


Every transaction begins with two primary phases: negotiation and drafting. Mark Brown’s experience as a trial lawyer, in-house counsel and mediator brings perspective and value to each step in the process of inking a good deal.


Mark is a skilled mediator, helping adversaries find creative ways to resolve their disputes prior to trial. He currently is one of only four lawyers in St. Charles County certified as a mediator by the U.S. District Court for the Eastern District of Missouri. He has even used his talent as a mediator to help other lawyers settle their disputes with their own clients. This mediation experience gives Mark’s clients a competitive edge when he negotiates on their behalf.



  • "Unquestionably, Mark is an outstanding attorney. Two of the key qualities that set him apart from his peers are his integrity and work ethic. I trust him implicitly and would recommend him to anyone seeking a seasoned and highly skilled attorney."

    John J. Sardar, Chief Compliance Officer
    Noble Energy, Inc.

  • “Mark Brown is a man of integrity. He tells you the truth about your case and if he takes it on, then he works it like it’s the most important case he has. Mark is known for his strong preparation but is also magical in front of a jury. At the end of our trial, after a favorable verdict, several jurors approached us and commented on how different Mark is than most lawyers they’ve encountered before. That’s the impact Mark has on everyone around him. He’s the real deal.”

    Beth Chesterton, Owner

  • “When a dispute with another investor threatened my ownership of my first business, Mark Brown found a clever way to leverage a provision of my contract with the investor. He saved me from losing my entire investment, and he even found a way for me to avoid paying attorneys’ fees. I don’t know what I would have done without his representation.”
