Ryan is the founder and managing partner of Clarkson. Motivated by a desire to deliver justice for the underserved, the underprivileged, and the underdog, Ryan has prosecuted hundreds of consumer class actions involving defective pharmaceutical drugs and medical devices, illegal employment practices, securities violations, cosmetics mislabeling, food misbranding, data breaches, and insurance carrier bad faith. He was the first attorney in the United States to pursue justice for victims of fluoroquinolone antibiotics who suffered permanent and disabling nerve damage. A force for accountability in how big corporations label, advertise, and market consumer goods, Ryan recently obtained the largest ever slack-fill settlement in U.S. history.
Ryan is a Director Emeritus for the Los Angeles Trial Lawyers Charities (LATLC), which provides food, clothing, shelter, and financial aid to underserved and marginalized communities. Ryan also co-founded and serves on the board of directors of the Adam Clarkson Foundation, which supports the higher-education needs of children who have lost a parent.
In his free time, Ryan loves to travel with his family, exploring different cultures and cuisines together. You can also find him pulling up from 30 feet on the blacktop, shredding the gnar, or splitting fairways with 300-yard bombs.
Ryan is proficient in French, Farsi, and Spanish.
