John Langdoc is no stranger to the scientific and medical issues in the cases he handle. Before becoming an attorney, John was a scientist who studied the brain. At Baylor College of Medicine John researched the brains of people with schizophrenia, depression and autism. Earlier, in graduate school, he helped discover that some prescription anti-depressants can cause birth defects in the brain.

As a lead trial attorney, John has been successful in obtaining some of the most significant verdicts of their kind, across the country. Some of his recent verdicts include a $9M verdict against Dow Chemical for a man who was exposed to carcinogens while working at their plant, Dow has announced that it plans to continue to have lawyers fight the verdict on appeal; a $20M verdict for a woman who was unknowingly exposed to carcinogens from drywall when she helped her husband clean up on some home remodeling projects, the verdict was upheld on appeal in California; a $12M verdict for a man who was exposed to carcinogens at a paper mill, the verdict resulted in a settlement agreement the day after the verdict in Pennsylvania; and an $11M verdict for a man who was exposed to carcinogens as a painter.

John is a frequent lecturer at continuing legal education seminars for attorneys. He is typically asked to lecture on his experiences working on significant legal cases, and focuses on his belief that the best thing lawyers can do is work on their cases like they were never mis-trained to spin and distort the truth. He has been elected a Super Lawyer Rising Star, and was elected a Shareholder and Lead Trial Attorney at Baron & Budd faster than any lawyer in the firm's history.
