A Lifesaver After a Devastating Medical Error

After a surgical error left my husband with permanent complications, we were overwhelmed. Hiring Ron Mercaldo was the best decision we made. His 55 years of experience, particularly his deep knowledge of medical malpractice, was immediately evident. He explained the complex legal and medical issues with clarity and patience. Knowing he has tried over 100 jury trials and secured record verdicts gave us immense confidence. We felt represented by a true master of his craft, which his recent 'Lawyer of the Year' recognitions only confirm. Ron and his team at The Mercaldo Law Firm were relentless, professional, and deeply compassionate. They secured a settlement that ensures my husband's lifelong care. We are forever grateful.
