a Korean concept that recognizes the importance of reading the moods, tone, and goals of individuals within a group, and adjusting one’s actions to meet those group dynamics. Yoona is motivated by this interpersonal aspect of her collaborative efforts in the legal profession-including those with co-counsel, Keller Rohrback colleagues, and clients. Her leadership ability and passion for both teamwork and advocacy are valuable tools that Yoona uses to guide her teams in identifying difficult problems and finding effective and practical solutions for her clients.
Yoona’s work in Keller Rohrback’s complex litigation group is focused on environmental law, class actions, and the representation of government entities in litigation against corporate wrongdoers. With nearly two decades of litigation experience and a background in public relations, Yoona believes passionately in the legal system’s power to redress harm to vulnerable populations and communities and is strategic about navigating the unique nuances and considerations involved when representing government entities in public-facing litigation. She is well respected by her peers, as well as industry organizations, and has been honored by Benchmark Litigation, Best Lawyers in America, Lawdragon, and Oregon Super Lawyers.
Prior to her time at Keller Rohrback, Yoona worked closely with other members of the firm as co-counsel representing the State of Oregon in its case against Monsanto seeking to hold the corporate giant responsible for natural resource damages related to the sale and marketing of PCBs. She also represents the State of Maryland, State of Delaware, and City of Seattle in PCB litigation against Monsanto. Yoona also represents 19 Oregon school districts in litigation against JUUL Labs, Inc. and other e-cigarette manufacturers for targeting youth with their marketing and product design and addicting a new generation to nicotine. At her prior firm, Yoona most recently represented plaintiffs in a class action against Airbnb seeking changes to that company’s discriminatory booking policies, and individuals whose personal information was compromised by a data breach in a class action against the health insurer Premera.
Outside of work, Yoona enjoys cooking, skiing, knitting sweaters that people feel obligated to wear, and spending time with her litigator husband and two teenage sons.
