Claimed Lawyer ProfileSocial Media

Michael P. Thornton is founder and chair of Thornton Law Firm LLP. A nationally recognized expert on toxic tort litigation, Mr. Thornton graduated from Dartmouth College and Vanderbilt Law School. In the 1970’s he successfully undertook the representation of a number of shipyard and construction workers who had developed asbestos-related diseases. Over the years, the firm has grown to become the largest firm in the Northeast representing victims of asbestos and other toxic materials. The firm has brought justice to workers who contracted cancer and other health issues from exposure to chemicals, defective drugs, and defective products, and to children who have suffered birth defects from chemicals and pesticides to which their parents were exposed. The Commonwealth of Massachusetts and other states and local government have sought the firm’s expertise to address damage from threats to the public health. Multi-million dollar recovery from tobacco companies resulted from the firm’s work in these areas. Mike lead the firm to support many charitable causes; the most visible & important project involves cancer research. Mr. Thornton was approached by clinicians and researchers at Brigham and Women’s Hospital who were interested in studying mesothelioma, a then untreatable and invariably fatal form of asbestos related cancer. After making a multiyear commitment from his own firm, Mr. Thornton helped recruit several other donors. The program, begun in 2002, has made strides in cancer research generally, and has helped to revolutionize the treatment of mesothelioma, leading to longer survival and better quality of life for victims. Mr. Thornton also responded to a call to help establish a place for families of mesothelioma victims to stay, as the financial impact of staying in hotels can be devastating. The Thornton House was opened in 2008 and houses up to 9 families at a time. Mr. Thornton is a member of the Massachusetts, New Hampshire, & Maine bars.
