John Langdoc

John-LangdocJohn L. Langdoc is a partner at Kazan, McClain, Satterley & Greenwood in California and was most recently a trial lawyer and shareholder at Baron & Budd, P.C., in Texas.

Before becoming a lawyer, Langdoc attended Baylor College of medicine and was a scientist. He specialized in brain research. During graduate school, Langdoc expanded his research to study the effects of prescription drugs such as Prozac, to illustrate that mothers using such prescriptions birthed babies born with brain damage.

As a lawyer, Langdoc continues his legal practice directing his attention largely on scientific cases. He especially examines those surveys funded by industries that convey the hypothesis for safety of known industrial poisons. In 2015, on behalf of a California couple, Langdoc won affirmation that upheld a verdict of $48 million on the side of the mesothelioma patient and his wife. This victory for Langdoc occurred after the asbestos company’s many failed appeals. Legal 500 established the case as one of the nation’s most remarkable verdicts regarding toxins. The National Law Journal listed it among the year’s Top 100 Verdicts.

In addition to induction into the Texas Lawyer’s Verdicts Hall of Fame, Langdoc was validated in 2012 for having California’s highest verdict for toxic exposure, and placed first and second in 2011 for the largest Texas verdicts in product liability.

Langdoc was admitted into the Texas and California State Bars
