Mr. Thomas received his law degree from The University of Michigan Law School, and earned his undergraduate degree from Western Michigan University, where he was a Division I athlete.

Past Cases
Following are just a few examples of Mr. Thomas’ work for clients:
J.P. Morgan Chase – The worldwide financial services provider brought in Mr. Thomas to handle a matter before the International Arbitration Association that involved one of the largest credit card portfolios in the world. The lawsuit, which included jurisdictional disputes in New York and Houston, centered on the banking joint venture assembled to develop the co-branded Shell MasterCard. Facing off against Shell and Citibank, Mr. Thomas sought a substantial award against Chase’s joint venture partner, as well as a ruling that Chase was the owner of the accounts. After expedited discovery, the case was successfully tried before a Houston arbitrator before being resolved under confidential terms.
Occidental Petroleum Corp. – Mr. Thomas was hired as trial counsel in a high-stakes dispute following the company’s $3.6 billion acquisition of Altura Energy LP, the largest oil producer in Texas at the time. The defendant BP America Production Co. disputed Occidental’s marketing “call rights” involving oil and gas generated in the Texas Permian Basin. Mr. Thomas helped Occidental resolve the matter following a week of arbitration in Houston.
Reliant Energy – When investigators from the Securities and Exchange Commission (SEC) and the U.S. Commodity Futures Trading Commission leveled their aim at Texas-based Reliant Energy, the company’s board of directors called on Mr. Thomas to protect their individual interests. Government investigators set out to prove that Reliant had engaged in improper commodity trading practices in order to boost the company’s trading volumes and sales revenues. Reliant eventually agreed to a settlement with the SEC, but Mr. Thomas’ clients successfully emerged with no findings of wrongdoing.
King Ranch – When the owners of this historic Texas ranch found their property under siege, they called on Mr. Thomas to help unravel a 120-year-old legal battle. King Ranch founder Richard King was sued in the 1880s by the wife of a former business partner over her late husband’s interest in the 15,500 acres of land that later would become the centerpiece of the King Ranch cattle empire. That case eventually settled, with the business partner’s widow selling her property interests for $5,800. When the business partner’s heirs tried to undo the sale nearly 120 years later, Mr. Thomas successfully defended King Ranch by winning a ruling from the Supreme Court of Texas that preserved the earlier sale and confirmed the rightful owners of the King Ranch.
R.R. Street & Co. Inc. – Also known as Street’s, this company is one of the nation’s leading providers of detergents and process additives to the dry cleaning industry. Mr. Thomas’ track record on behalf of the company is just one reason why he has been Street’s go-to national counsel for more than 15 years. In addition to wins in courtroom trials and appeals, Mr. Thomas has become a trusted adviser to the company’s leaders based on his experienced counsel and proven business acumen. He has successfully defended Street’s in numerous individual cases filed across the U.S. by dry cleaners, local municipalities and various water authorities. In all, Mr. Thomas and his team have defeated hundreds of millions of dollars in product liability claims brought against the company. In addition to prevailing in multiple product liability jury trials in California and Texas, Mr. Thomas also obtained a win for Street’s at the Supreme Court of Texas in a case of first impression under the Texas Solid Waste Disposal Act.

Jurisdictional Context
Why Local Counsel Matters in Houston
Practicing law in Texas. Legal matters in Texas are governed by state-specific rules of civil and criminal procedure, statutes of limitations, and substantive law. Cases originating in Houston are typically filed in the local municipal court or the appropriate Texas state district court, depending on subject matter and amount in controversy. An attorney licensed in Texas brings working knowledge of local procedural deadlines, judicial practices in this venue, and the substantive law that applies to cases brought here. Out-of-state attorneys generally cannot represent clients in Texas courts without local counsel or pro hac vice admission.
Houston Courts and Legal Process
Choosing a Houston-based attorney means your counsel already knows the local docketing timelines, preferred filing formats, and how individual judges typically rule on procedural motions — details that only come from practicing in this jurisdiction day after day. That local familiarity can translate to better strategy, faster filings, and fewer costly surprises.
