Meet our Commercial Litigation Attorneys

Since 1946, Gray Ritter Graham in St. Louis has built a reputation for effective representation of individuals and businesses harmed by others. Attorney Don Downing, former chief deputy attorney general for Missouri, leads our commercial litigation, class action, and mass torts practice.

When you are our client, you are the most important part of our team. And, unlike most firms that handle commercial litigation, we often are willing to offer our services on a contingent fee basis.

GRG attorneys Don Downing, Gretchen Garrison, Kaitlin Bridges, Jack Downing, Joan Lockwood, and Morry Cole are all experienced and willing to help you with any commercial litigation cases you may have.

Commercial Insurance

Individuals, businesses and government agencies carry insurance to help when things go wrong. But often times, commercial insurance carriers wrongfully deny coverage and refuse to pay claims. The lawyers at Gray Ritter Graham have handled countless insurance disputes, often with millions of dollars at stake. If your insurance company is in the wrong, let us help.


Fraud can occur before or during transactions of all kinds and includes both affirmative misrepresentations and omissions. Someone might make a misrepresentation that induces execution of a contract or that convinces the recipient to take some other action to his or her detriment. The misrepresentation might involve services, products, or property. We have decades of experience with business fraud and stand ready to assist.

Tortious Interference

Tortious interference can be with a contractual or business relationship, whether existing or prospective. Claims of tortious interference often are combined with other wrongful conduct and need careful review to determine the existence and strength of all the elements for legal response. Our team has the expertise to advise and represent you.

Qui Tam/Whistleblower Claims

Qui tam or whistleblower laws are designed to protect employees who witness and report their employers engaging in illegal activity. Those who have simply done the right thing should not be subject to repercussions. At Gray Ritter Graham, we stand up for whistleblowers and protect their rights. We can help if your employer has engaged in retaliation, such as a demotion or even termination.
