Sam Moore joined Riggan Law Firm in 2012. Since then, Sam’s practice has focused on employment law, primarily representing employees in workplace disputes. He has experience litigating a wide variety of employment matters in state and federal court, including unpaid overtime violations, minimum wage violations, independent contractors misclassifications, restaurant tip pool violations, workplace harassment, workplace discrimination, workplace retaliation, violations of the Uniformed Services Employment and Reemployment Rights Act (USERRA), and breach of contract claims. Sam also represents clients on charges of discrimination filed with the Equal Employment Opportunity Commission (EEOC) and similar state agencies.

In 2020, Sam was presented with the “Top Plaintiffs’ Verdict Award” by Missouri Lawyers Media. Sam has also been selected to the Missouri Rising Stars list by Missouri and Kansas Super Lawyers Magazine (an honor that is limited to no more than 2.5% of the attorneys within each state).

In 2019, Sam and Russ Riggan obtained a 19.97 million dollar jury verdict for our client at trial in St. Louis County Circuit Court. Our client, a long-time employee of the St. Louis County Police Department, alleged that he had been denied a promotion to the position of Lieutenant over twenty times due to unlawful sex discrimination and sex stereotyping. In addition, our client alleged he was retaliated against for seeking legal redress regarding the promotion denials. The jury returned verdicts in favor of our client on both claims, and following post-trial motions, the trial judge increased the total size of the judgement to 20.65 million dollars. Shortly after the trial victory, the St. Louis County Police Department promoted our client to the position of Lieutenant, where he was put in charge of the Department’s Diversity and Inclusion Unit. Wildhaber v. St. Louis County, Missouri, 17SL-CC00133.

Sam has served as class counsel in many class/collective actions seeking unpaid wages on behalf of large groups of employees. He also advises clients on complex employment law issues outside of the litigation context, such as reviewing/drafting employment contracts, non-competition agreements, non-solicitation agreements, and confidentiality agreements.

Sam earned his J.D. from Washington University School of Law in St. Louis. While in law school, he clerked with the St. Louis District Office of the EEOC. Prior to joining Riggan Law Firm, Sam served as an attorney with the trial division of the Missouri State Public Defender System. As a trial attorney with the Public Defender System, he represented his clients throughout all stages of each case and acquired extensive jury trial experience.
