Mario D’Angelo has led the fight against the biggest pharmaceutical firms in the country such as Wyeth Pharmaceuticals (formerly known as American Home Products), SmithKline Beecham also known as GlaxoSmithKline, and Johnson & Johnson recovering more than 250 million dollars for his clients within the last ten years. It is the result of thousands of hours arguing these cases and fighting for what he believes is right and true in front of judge and jury alike since he was admitted to practice. A good portion of what he has accomplished has also come from traveling the globe, meeting personally with his clients and retaining the experts that are recognized to be the most trusted, knowledgeable and respected in their fields.

Mr. D’Angelo has also fought and recovered millions of dollars from Nursing Homes which have neglected their patients and caused intolerable permanent injuries or even death.

Whether mass tort, product liability, general negligence or medical malpractice, Mario D’Angelo has left no stone unturned nor question unasked to get what his clients deserve from those who have wronged them. For this, he has just been certified as one of the Top 100 Trial Lawyers of 2008 from the American Trial Lawyers Association.

Today Mario D’Angelo is happily married with five children and living on Long Island working harder than ever for you.
