Motivated by a desire from an early age to deliver justice for the underserved, the underprivileged, and the underdog, Ryan has prosecuted hundreds of consumer class actions involving fraudulent uses of artificial intelligence, defective pharmaceutical drugs and medical devices, greenwashing, illegal employment practices, 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 false advertising settlements involving fraudulent packaging, free-from food mislabeling, and false collagen cosmetics claims in U.S. history.
