Full Biography

Joseph Ryan Riegerix forged his passion for justice through years of representing clients ranging from individual consumers, farmers, and cancer patients to Fortune 100 businesses and corporate executives. He has a broad background of litigation experience in practice areas such as personal injury, products liability, premises liability, mass torts, insurance bad faith, toxic torts, pharmaceuticals, medical devices, and employment law, among others. He is particularly proud of the opportunities he has had to litigate on behalf of victims of sexual assault against both the perpetrators and the institutions which enable and protect them.

Not long after his law school graduation in 2013, Mr. Riegerix joined a large Chicago-based law firm where he practiced in a capacity he had not envisioned - defending companies in litigation over claimed defective products, dangerous premises, and toxic torts including asbestos litigation. He gained invaluable insight into the methods and mindset of defense counsel during this time and attended hundreds of depositions across the United States. After many years, he joined a boutique law firm in St. Louis, Missouri where he represented companies, employers, and executives in employment, business, and commercial litigation. He pursued complex matters such as trade secret misappropriation and piercing of the corporate veil to obtain damages from individuals hiding behind shell companies. He also counseled corporate clients directly on internal policies and litigation strategy, through which he learned the tactics a company may employ to defend its interests and avoid liability.

After many years defending against alleged wrongdoing, Mr. Riegerix felt unfulfilled. Feeling that his practice at the time lacked true purpose, he knew a drastic change was in order. As a result, he moved to Denver and joined the plaintiff’s bar with a renewed vigor and determination to use his skills and experience to help individuals harmed by those who put profits over people. He joined a small yet nationally renowned firm where he pursued mass torts against pharmaceutical companies, medical device manufacturers, and agricultural companies. His passion for fighting on behalf of the “small guy” against the “big guy” grew exponentially as he represented thousands of persons who developed cancer following use of Roundup weed killer in litigation against Monsanto.

Mr. Riegerix was born and raised in St. Louis, Missouri. He earned an academic scholarship to Pepperdine University in Malibu, California, where he majored in philosophy and graduated cum laude. Mr. Riegerix then attended law school at Wake Forest University in Winston-Salem, North Carolina, also with an academic scholarship. He additionally spent a semester as an intern in Washington, D.C. and studied abroad in Florence, Italy, Shanghai, China and Nice, France.
