Kathryn (Katie) Grzenczyk Mantoan is Of Counsel in Orrick's Employment Law & Litigation group, working across the San Francisco and Portland offices. She focuses on high-stakes employment litigation, compliance counseling, and litigation avoidance measures. Her practice has a particular emphasis on complex class actions and developing areas of the law including pay equity and pay transparency, and she co-chairs Orrick's Pay Equity Task Force.
Katie was a part of the trial team that obtained a complete dismissal for Oracle in OFCCP v. Oracle, a high-stakes systemic compensation discrimination case that garnered national media attention. Katie and her co-counsel were named "Litigators of the Week" by American Lawyer for the win. Two years later, Katie and her co-counsel were named Runners-Up by American Lawyer for securing decertification of a 3,000-person putative equal pay class action for Oracle. Previously, she received California Lawyer’s Attorney of the Year Award in 2016.
In fall 2023, Katie co-first chaired a two week federal jury trial in Oregon and obtained a verdict against the client's former general manager, who set up a competing business while employed, on claims for breach of fiduciary duty and intentional interference.
She also regularly publishes on employment law developments, having presented on topics to three separate state bar associations and a host of national and regional legal and academic conferences. Recently, her writing and speaking engagements have focused on strategies for working with expert witnesses in complex employment cases.
