Abby Risner’s extensive trial experience nationwide on behalf of companies gives her a keen understanding of what it takes to efficiently and effectively handle complex disputes. In her complex commercial litigation and class action practice, she defends energy companies, franchisors, manufacturers and distributors against claims related to consumer fraud, advertising, franchise termination, unfair business practices, contract disputes and other matters. Abby has tried cases to verdict and has experience in every phase of litigation, including as first chair in court and arbitration.

Abby is the leader of Greensfelder's Energy Industry Group and routinely represents clients in petroleum marketing disputes, and advises on business issues associated with the Petroleum Marketing Practices Act (PMPA), retail motor fuel marketing, including pricing, contracts, antitrust, and termination issues. She has defended claims against oil companies related to termination under the PMPA and franchise laws, breach of contract and fraud claims, alleged unlawful motor fuel pricing practices, deed restrictions, and consumer protection claims. Her knowledge of the energy sector and the trial process has made her an important resource for the global companies she represents.

Abby also leads the Litigation Class Action group. Her experience includes prevailing on class claims through dispositive motions, complex class action settlements, counseling on the class action notice and claims process, as well as trial of a class action. Abby has extensive experience defending class actions in federal and state courts, including the Southern District of Illinois, Eastern District of Missouri, Western District of Missouri, Madison and St. Clair Counties in Illinois, and St. Louis City and St. Louis County in Missouri.

In her franchising and distribution practice, Abby counsels clients on termination of franchisees, distributors and sales representatives, as well as the litigation of resulting claims in court and arbitration (including international arbitration). She advises on state franchise, distributor and sales representative statutes and works with distributors facing disputes that arise as they bring their products and services to market.

During law school, Abby was a student extern in the United States District Court for the Eastern District of Missouri.
