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.
In fall 2023, Katie co-first chaired a two week federal jury trial 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.
Previously, Katie received California Lawyer’s Attorney of the Year Award in 2016 and was named a Northern California Super Lawyers "Rising Star" for seven consecutive years. She regularly writes and 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.
Katie started her career at Orrick in 2004 and returned in 2015. From 2011 to 2014, she was an associate at a litigation boutique in San Francisco where she handled employment and constitutional law matters.
