Diane Moore has devoted her career to representing plaintiffs in complex litigation.  Since joining Korein Tillery in 2000, she has worked on all aspects of a variety of complex cases, from inception through appeal, including cases under federal and state securities laws, the Real Estate Settlement Procedures Act (RESPA), the Employee Retirement Income Security Act (ERISA) and the Telephone Consumer Protection Act (TCPA).

Diane is currently part of a team of lawyers who represent the National Credit Union Administration in residential mortgage-backed securities (RMBS) litigation against many of the largest Wall Street investment banks.   She is also part of a team that represents certified classes against two of the largest title insurance companies in Chicago for alleged RESPA violations.  Earlier in her career with Korein Tillery, Diane assisted on numerous successful ERISA cases challenging the calculation of retirees’ lump sum pension benefits under “cash balance” pension plans that resulted in hundreds of millions of dollars of additional pension benefits for retirees of several Fortune 500 companies.  She was also appointed class counsel in several TCPA class actions.

Diane received her Bachelor of Arts magna cum laude from St. Louis University in 1993 and her Juris Doctor cum laude from St. Louis University School of Law in 1998, where she was awarded Order of the Woolsack and where she served as Associate Editor of the ST. Louis-Warsaw Transatlantic Law Journal. She spent the two years following law school as a judicial clerk for the Honorable Lawrence Mooney, Missouri Court of Appeals Eastern District.

Diane was born and raised in St. Louis.  She moved to the Hawaiian island of Maui in 2008 and currently resides in San Diego, California.  She is an avid reader and enjoys travel and painting.  For many years, Diane volunteered as an English as a second language tutor for Catholic Charities.
