Expert witness evidence in EMF tort case ruled inadmissible

In order to meet growing demand, Puget Sound Energy decided to replace an existing 52-year-old substation in Kirkland with a new and considerably larger one, which went on line in 2010. A group of homeowners sued PSE in King County Superior Court, alleging that the electromagnetic fields emanating from the substation were a public and private nuisance. The Court ordered plaintiffs to submit scientific evidence, which included expert testimony.

With Jeff Thomas’ help, PSE moved to exclude the plaintiffs’ expert’s declaration as inadmissible. At the end of a several-day evidentiary hearing, the Court ruled that the homeowners’ expert was not scientifically reliable. The homeowners appealed. The Court of Appeals certified their case to the Washington Supreme Court for direct review. In 2012, the justices held that this testimony had been properly excluded. A plaintiffs’ ruling on this case could have had broad implications, potentially affecting 150 million houses in America.


Groundbreaking jury trial over Madoff-linked audits

This 2015 jury trial was the first successful lawsuit in the country against an auditor over losses tied to the largest Ponzi scheme in U.S. history. In 2010 FutureSelect Portfolio Management Inc., located in Redmond, Washington, sued Ernst & Young over faulty audits of a Madoff-linked feeder fund. Jeff Thomas represented the plaintiff, as co-counsel with noted Los Angeles trial lawyers Thomas, Alexander, Forrester & Sorensen LLP. In 2015, after a five-week trial, the jury sided with investors in this complicated case, finding that the accounting giant negligently signing off on audits of billions in assets that did not exist. The jury awarded $16 million in damages to FutureSelect. The award helped to recoup a portion of the many millions of dollars that FutureSelect had lost in its investment in a Madoff-linked feeder fund.


$130 million settlement in trade secret case

Move and Zillow are major competitors in the online real estate market. When two senior executives of Move left that company in 2014 and went to work as senior executives for Zillow, Move (and its co-plaintiff the National Association of Realtors) filed a lawsuit against the two executives and Zillow for misappropriation of trade secrets, breach of fiduciary duty, and other claims. The lawsuit involved allegations that the two executives had purposefully destroyed evidence. 

After two years of preparation, the case was scheduled to go to trial in June 2016. Working with co-counsel, Jeff Thomas, Michael Rosenberger, Mark Wilner and Michael Brown obtained a $130 million settlement on behalf of Move and the NAR.

Bar/Court Admissions


If I weren’t a lawyer, I’d be playing guitar in a rock ‘n’ roll band. That’s what I did for ten years before attending law school. I played in bands called Edge City, Heart of Gold Band, and Stark Raven. I still play for my own enjoyment. I have a studio and my brother and I record there. In a way, much of being a courtroom lawyer is all about performance.

Outside the office, I enjoy spending time with my family. I enjoy softball, baseball and golf. My new passion is barbeque.  Some of my other hobbies include photography, watching professional baseball, and world travel.
