Rosalie Swingle is an associate in Lathrop GPM’s Litigation & Dispute Resolution practice group. Her practice focuses on general and complex commercial litigation, and she works on a variety of matters including property disputes, closely-held business disputes, consumer-protection disputes, and financial service disputes.  She has also served as an appointed advocate for individuals incarcerated in federal prison litigating Section 1983 claims.

Rosalie is an active listener and critical communicator with unique insights to offer her clients based on her collaborative work experience, including executing a campaign field strategy to elect the first woman for a state-house district, and partnering with individuals, associations, and municipalities to achieve desired education and health outcomes through community development. Rosalie seeks the best pretrial outcomes for her clients, and she achieves these outcomes by providing excellent service throughout the entire litigation process, applying thoughtful, detailed analysis to each written submission and making strategic oral arguments at every court appearance on behalf of her clients.

Rosalie’s passion for advocacy is also grounded in her community involvement.  She “gave a year of service,” working alongside dedicated educators in the Kansas City Public School District as a 2016–2017 City Year AmeriCorps Member. She continues to invest in her community through athletic and academic mentoring programs as well as pro bono partnerships with stakeholders in the St. Louis metropolitan area to reduce vacant properties in historic neighborhoods. Rosalie also enjoys leading Lathrop GPM’s involvement with the Motion for Kids program, an annual toy drive which collects holiday presents for local children impacted by the legal and foster care system.

Prior to joining Lathrop GPM, Rosalie received her juris doctor from Washington University School of Law and is an alumnus of the Lathrop GPM Summer Associate program.
