A Lifeline After a Defective Medical Device

When a faulty medical implant left me with chronic pain and mounting medical bills, I felt overwhelmed. Mr. O'Leary's three decades of experience, particularly his recognized expertise in product liability and mass tort litigation, were immediately apparent. He and his team at O'Leary, Shelton, Corrigan meticulously explained the complex process of joining a larger action, ensuring I understood every step. His deep knowledge, honed from his Saint Louis University School of Law education and long-standing practice in Missouri, was invaluable. We achieved a settlement that secured my future medical care and provided true financial stability. His professionalism is matched only by his genuine compassion. I cannot recommend him highly enough for anyone facing similar corporate negligence.
