Shaun Lieser

Shaun Lieser developed an interest in practicing law at an early age, but his commitment to serving others became deeply personal after the sudden loss of his mother in 2007. That experience shaped the direction of his career and ultimately led to the founding of Lieser Law Firm LLC. Since that time, Shaun has focused his legal practice on representing individuals and families who have suffered serious injuries or loss due to the wrongful conduct of others.

Raised in a hard-working union family, Shaun attended St. Louis University High School, where he participated in multiple sports. His dedication on and off the field earned him a soccer scholarship to Vanderbilt University in Nashville, Tennessee. At Vanderbilt, he earned a bachelor’s degree in Communications before returning to his hometown to attend St. Louis University School of Law.

After obtaining his law license, Shaun accepted a position with his trial advocacy professor’s personal injury law firm in Collinsville, Illinois. That experience provided a strong foundation in courtroom advocacy and client representation. With a desire to serve clients closer to home, Shaun went on to establish Lieser Law Firm LLC, now serving clients throughout St. Louis, Missouri, and the surrounding communities.

Shaun’s practice is dedicated to Personal Injury Litigation – Plaintiffs, including matters involving serious injuries, wrongful death, and other claims arising from negligence. He is committed to providing clear communication, thorough preparation, and compassionate guidance throughout the legal process for clients in St. Louis, Missouri.

Outside of his legal work, Shaun values time with his family and remains actively involved in his community. A lifelong athlete, he supports organizations that promote opportunity and inclusion in sports and serves as an advisory board member for the Disabled Athlete Sports Association.
