Our team is driven by an unrelenting demand for achievement, seeking results and best-case scenarios.


At GSL Trial, every case and situation is viewed as an opportunity to go above and beyond what is expected by our clients.



Our Founder, G. Stephen Long has tried more than seventy jury trials and handled cases in federal and state courts throughout the United States. He has tried cases or argued in nineteen different states, four State Supreme Courts, and five Federal Courts of Appeal. He received national recognition for trying large commercial cases on a contingency basis and has recovered more than $500 million for a variety of clients ranging from individuals to small businesses to large corporations. Our firm can be engaged traditionally, or in some cases through alternative billing.


Steve also has extensive class action case experience, including lead counsel for a certified settlement class in Kansas and Missouri against Wal-Mart Stores, Inc. arising out of wage and hour disputes, lead class and trial counsel for military retirees seeking a declaration that state taxing scheme was unconstitutional, and lead trial counsel for a class of investors asserting claims as a result of the roll-up of a master limited partnership. Although Steve's trial experience is deep and diverse, our firm’s focus is getting our clients the best possible result as quickly as practical. Sometimes settlements are the clients’ best result. You want a seasoned trial firm to assure you will achieve the best results in a more pertinent manner.
