Cynthia Hennessey

I am Cynthia M. Hennessey, founder of Hennessey Law Firm, LLC, with over 30 years of combined medical and legal experience serving injured workers and accident victims across Missouri and Illinois. My unique background as both a registered nurse and attorney (including former insurance defense attorney) give me an unparalleled advantage in understanding complex injury cases and fighting for the compensation my clients deserve. Based in St. Louis, my all-female firm focuses on workers' compensation and personal injury cases throughout Missouri and southwest Illinois. I handle construction accidents, healthcare worker injuries, motor vehicle accidents during employment, slip-and-fall incidents, catastrophic workplace injuries, PTD and PPD claims. I have a proven track record of success, from securing permanent total disability benefits for injured workers to negotiating significant settlements in complex personal injury cases. My medical insight as a nurse provides a distinct advantage in comprehensively understanding your injuries and advocating for full and fair compensation. My firm combines fierce advocacy with deep compassion. We understand workplace injuries create not just physical pain but financial stress and family disruption. We fight tirelessly against insurance companies and employers who deny or delay necessary medical treatment, guiding clients through complex legal systems with care, strength, and unwavering support. As a former insurance defense attorney, I know how insurance companies operate and use that insight to benefit your case. My dual background as a nurse and attorney allows me to navigate medical complexities and fight for what’s fair. What truly sets me apart is my spiritual perspective. I treat my clients like family, taking the time to listen and support them through every phase of their legal journey. I deliver proven results—call (314) 821-9696 for a free consultation.
