Kayla Delgado Grundy Managing Associate Trade Secrets Litigation, Employment Law & Litigation

San Francisco

Employment litigator Kayla Delgado Grundy blends creativity and tenacity to fiercely protect her clients.

Companies are often unwittingly out of compliance, particularly those which operate in states such as California, which have rapidly evolving, employee-friendly regulations. To prevent individual discrimination or harassment allegations from spiraling into class actions, Kayla finds innovative solutions to quickly and quietly resolve such matters. She applies that same finesse when handling highly sensitive trade secret matters, which also require quick and decisive action to preserve her client’s reputation.  

In addition to resolving problems before they escalate, Kayla also helps clients succeed in litigation when necessary. Undaunted by opposing counsel, government agencies or difficult fact patterns, she successfully defends clients from a variety of employment claims in state and federal court.

Prior to joining Orrick, Kayla participated in Berkeley Law’s Death Penalty Clinic, a clinic designed to enable law students to provide high-level, supervised representation to clients facing capital punishment. Through her work in the clinic, and through similar pro bono work in her legal practice, Kayla received hands on experience in appellate litigation and investigations.
