Equality For All.

Civil Rights, Employment Discrimination, and Criminal Defense Litigation


About mark caviness



I’m Mark Caviness, the founder of Caviness Law Firm. I chose my practice because I want to use my knowledge to ensure that all people are treated equally and with dignity.

Since entering law school at Saint Louis University (graduating in 2004) I have loved calling St. Louis home. After graduation, I began working for the federal court here in St. Louis as a law clerk for the Hon. Rodney W. Sippel, United States District Judge. From 2006 through 2017, I served as one of the court’s specialists on civil rights law. I also regularly dealt with all aspects of employment discrimination cases and the constitutional rights of criminal defendants.

I have a long history of service to the public. Before law school, I was a paramedic for the City of San Diego. Other experience includes volunteering for the San Diego Center for Children and Big Brothers Big Sisters of Eastern Missouri. These experiences motivated me to find new and better ways to serve people.

I started this firm because I believe that I, together with my clients, can make a difference in St. Louis and because I wanted to get off the sideline and into the fight for equal treatment and the preservation of our constitutional rights.

For more information on my credentials, please see my resume. I look forward to having an opportunity to work on your behalf. 



Employment Discrimination

My practice includes all areas of employment discrimination law. American workers are protected from discrimination under several federal and state laws. For example, Title VII of the Civil Rights Act of 1964 and the Missouri Human Rights Act protect workers from discrimination based on their race, color, religion, sex, or national origin. Title VII further protects women from discrimination based on pregnancy, childbirth, and related medical conditions. Other federal laws protect workers from discrimination based on age, disability, basis of citizenship, and genetic information. And the Equal Pay Act requires employers to give men and women equal pay for equal work. There are several recent and exciting developments in LGBTQ law. While there are currently no state or federal laws prohibiting discrimination, several municipalities in Missouri prohibit discrimination based on both sexual orientation and gender identity, including Clayton, Kirkwood, Olivette, St. Louis City, St. Louis County, and University City. And a recent case from the Missouri Court of Appeals for the Western District held that the firing of an effeminate gay man violated the Missouri Human Rights Act’s prohibition on sex discrimination. I will zealously prosecute on behalf of any individual who has been discriminated against, regardless of whether the law is settled or emerging.

Please be aware that you must file a charge with the Equal Employment Opportunity Commission (EEOC) or the Missouri Human Rights Commission (MHRC) within 300 days of the discriminatory action. See here for instructions on filing with the EEOC and here for instructions on filing with the MHRC.  I recommend dual filing with both agencies.

Civil Rights

Title 42 U.S.C. § 1983 allows citizens to sue government officials or entities if they violate our fundamental constitutional rights. The Bill of Rights, or the first ten Amendments to the Constitution, guarantee every American the freedom to speak, to practice their religion, to petition the courts for grievances, to peacefully assemble, to be free from unconstitutional searches and seizures, and freedom from excessive punishment, among other things. If you have suffered a constitutional injury of any type, I can help.
