About Stephanie Angkadjaja

Stephanie Angkadjaja has a unique understanding of the technical and business aspects of the refining industry and the laws that regulate it. That's because she worked as a chemical engineer for the world's largest publicly traded international oil and gas company, acting as an environmental advisor and process safety engineer during the day while earning her law degree in the evening. That experience informs her perspective on the safety, environmental and health issues and major accident response matters that clients engage her group to handle.

Industry work experience leads to efficiency and relatability

Because she’s walked in the shoes of her team's clients, Stephanie is able to approach her work more efficiently and relate to her clients' concerns. Her experience as a refinery chemical engineer included process engineering; project management; Title V air permit, EPA RMP and Cal/OSHA PSM compliance; and process safety engineering. In her role as process safety engineer, Stephanie supported the refinery's response to multiple government agency investigations of a major workplace incident, previewing her current practice at Katten. This breadth of "real world" work experience translates to an ability to quickly get to the heart of issues she is researching or otherwise counseling on.

Stephanie is also a registered patent attorney and member of Katten's Patent Litigation team. During law school, Stephanie completed the Intellectual Property Law concentration and participated on the school's Saul Lefkowitz Trademark Moot Court Competition team.
