Jennifer S. Griffin

Jennifer has successfully represented clients in the public and private sectors for over 20 years. Before entering private practice, she interned for the Eighth Circuit Court of Appeals, clerked for the Supreme Court of Missouri, drafted legislation for the Missouri General Assembly, and litigated tax cases for the Missouri Department of Revenue. 

Jennifer has a diverse practice focused primarily in the areas of administrative and regulatory law, business litigation, and advertising. She drafts legislation and regulations, and counsels clients regarding business activities and issues. Jennifer also advises clients concerning the conduct of promotional activities such as contests, sweepstakes, raffles and loyalty programs, and drafts promotional rules and associated marketing materials.  

She practices before local, state and federal courts, departments, agencies, boards and commissions. She routinely assists clients with matters such as permitting and licensing; defending asserted violations of state and federal law; litigating business disputes; challenging statutes, ordinances, and regulations; and appealing government decisions, contracts, and awards. Jennifer represents both for-profit and nonprofit entities, as well as individuals, cities, and counties.
