Proven Trial Success

In 2016, Sean had the fourth most influential verdict in the United States according to Courtroom View Network, stemming from a slip and fall at Lowe’s in which his client suffered a TBI after she slipped, fell, and knocked down a three-foot yellow warning cone. Lowe’s top offer before the verdict was $1,400,000.00, and the referring plaintiff attorney offered to resolve the case for $1,749,999.99. The jury returned a verdict in the amount of $16,430,000.00.

Sean’s trial success continued with two verdicts in 2018 in the amounts of $20,000,000.00 and $3,382,000.00. Sean’s verdict of $20,000,000.00 was recognized as the fourth most influential verdict in the United States according to Courtroom View Network, stemming from a negligence case against an HOA for failing to maintain its swing set. The HOA’s top offer before trial was $400,000.00, and the referring plaintiff offered the HOA to resolve the case for $949,000.00. The plaintiff in the case suffered a TBI.

Sean’s trial success continued in 2019 as he obtained a verdict of $645,814.33 in which there was a 16-day gap in treatment after the initial wreck, and then, after eight months of physical therapy treatment, there was a three and a half year gap in treatment before the plaintiff obtained further treatment for his back injury. The top offer from the defense was $50,000.00, and the referring attorney agreed to accept $180,000.00 to resolve the case prior to trial.

Later that year, Sean received an honorable mention from Courtroom View Network as having one of the year’s most impressive trials for his work on a medical malpractice trial where his client suffered a TBI. Sean asked for $63,000,000.00 in closing arguments and the case settled before the jury returned a verdict.

In 2020, Courtroom View Network named Sean to its “Who We’re Watching” list. Courtroom View Network says that after more than a decade of capturing trials for its streaming network, the lawyers on this list are its best of the best of the decade and are the lawyers that other lawyers should watch if they’re looking to improve their craft.

In 2021, Sean obtained a $38,750,000 verdict on behalf the mother of an 11-year girl who was killed by a garbage truck while crossing the street in a marked crosswalk. The top defense offer before trial was $1,000,000.

In 2023, Sean was part of the trial team which secured a jury verdict of $485,000,000 in New Mexico. We believe this is the largest single-plaintiff sexual abuse verdict ever. He also obtained a $48,630,000 verdict on behalf Amy Geiler, a woman left in a locked-in state as a result of medical negligence. We invite you to read Amy’s story here.

In February 2024, Sean secured a $20,000,000 verdict in a product defect case. The trial, which began in late 2023, took three months.


Sean is a proud graduate from the University of Nevada, Las Vegas. In 2000, he received a Bachelor or Arts in Political Science. Soon after, he graduated cum laude from UNLV’s William S. Boyd School of Law in 2003. During his time at the Boyd School of Law, he was a staff editor of the Nevada Law Journal as well as a member of the National Moot Court team. As a law student he won the Society of Advocates oral argument competition.

After graduating from Boyd School of Law, Sean was employed at a high-profile criminal defense law firm. After working for this firm for over two and a half years, Sean made the decision to start his own firm. On January 1, 2005, Sean opened his own law firm with a single client and one employee. Today Claggett & Sykes Law Firm has over 60 employees, including over 20 attorneys.
