SAN DIEGO – October 15, 2025 – Kathleen Herkenhoff, a veteran litigator who has helped to secure more than $1.5 billion in recoveries for clients while advancing corporate governance reforms, has joined DiCello Levitt’s nationally recognized Securities Practice Group in San Diego.
Herkenhoff has more than 30 years of experience representing government entities, institutional investors, pension funds, and individuals in securities, consumer, antitrust, and/or shareholder derivative litigation, as well as representing both individuals and classes in employment and data privacy matters. She has appeared in courts nationwide, at both the state and federal level, and has frequently litigated before the Judicial Panel on Multidistrict Litigation and the Ninth Circuit Court of Appeals.
“We are delighted to welcome Kathleen to our expanding team,” said DiCello Levitt Securities Practice Group Chair Patrick Daniels. “Our San Diego-based group has worked with Kathleen for decades—she is a dynamic litigator with a proven track record of securing substantial recoveries and driving meaningful corporate governance reforms. Her depth of experience in securities, consumer, and shareholder derivative litigation will be a tremendous asset to our clients.”
Herkenhoff joins a growing Securities Practice Group. Earlier this year, the practice welcomed Partner Marisa DeMato in New York and Senior Counsel Stephanie Schroder in San Diego.

I look forward to contributing to the firm’s continued success and advancing impactful cases on behalf of investors and consumers.”
