Litigation Highlights

Umpqua Bank Litigation

Wynne was one of the trial lawyers who represented over 1,200 class members in a four-week jury trial against Umpqua Bank (now known as Columbia Bank). The plaintiff class alleged that Umpqua aided and abetted a fraudulent investment scheme by Professional Financial Investors (PFI). Plaintiffs argued that PFI ran a fraudulent scheme that used investor money to personally benefit PFI’s executives, including its principals Ken Casey and Lewis Wallach, pay other investors, and cover recurring shortages across its dozens of accounts at Umpqua. Ultimately, the jury could not reach a unanimous decision. Later, the parties reached a $55 million settlement weeks later, and the Court granted final approval on September 11, 2025. Judge P. Casey Pitts, who oversaw the trial, called the settlement an “excellent” outcome for the class.
