In 1968, when Byron Sims and Thomas Brown formed their two-man law firm, Brown Sims, the initial focus was to offer their clients in the maritime and energy industries a superior and wide variety of litigation services.

But along with the growth in these industries along the Texas Gulf Coast, Mr. Sims’ own personal ambition and desire to hire the best lawyers he could find resulted in unprecedented growth in his own practice. Impressed with the results they received from these two lawyers, Mr. Sims and Mr. Brown’s clients and carriers began requesting that the firm venture outside its traditional practice areas.

Forty-five years later, the once small firm has exploded into one of the top 25 largest law firms in Houston and one of the top 100 largest law firms in Texas. What was once a small and tailored practice with two lawyers, has grown to over 60 lawyers, assisting hundreds of clients in thousands of matters, and covering almost every conceivable industry.

Mr. Sims is well known and has long been recognized as one of Houston’s leading attorneys. He was honored as one of Houston’s Top Lawyers by H Magazine, and has been named a Texas Super Lawyer as featured in Texas Monthly.  Mr. Sims is also included in Best Lawyers in America.

Mr. Sims is Board Certified in both Personal Injury Law and Civil Trial Law by the Texas Board of Legal Specialization and has been certified as a Civil Trial Advocate by the National Board of Trial Advocacy.
