About

  • Attorney Gary DiMuzio is of counsel in the asbestos department at Simmons Hanly Conroy

  • During his career, Gary has represented plaintiffs in cases involving mesothelioma, lung cancer, leukemia, liver cancer, silicosis, plant explosions and environmental contamination
  • Fighting for Those Poisoned by Pollution Gary entered law school with the goal of helping those poisoned by pollution, concentrating his studies on environmental and occupational contamination law
  • As a law student and legal intern for the Environmental Defense Fund, he drafted the fund’s first successful lawsuit in Texas. “My early experience seeing law, science and policy interface created the impetus to understand sciences such as toxicology, epidemiology, biostatics, environmental studies, risk assessment, and exposure assessment in order to be the best advocate for my clients,” he said
  • With this underlying objective, Gary undertook environmental public health studies at the University of Texas School of Public Health concurrently with his law degree
  • He also worked on environmental issues with the Harris County Attorney’s Office Environmental Division/Harris County Pollution Controls lawyers and experts, as well as researching how the courts judged causation science and toxic tort experts for the University of Houston Environmental Liability Law Program

  • Gary has fought for the spouses and children of workers who were exposed to the deadly dust brought home by the workers and diagnosed decades later. “Many mesothelioma victims have never filed a lawsuit and thought they would never do so,” he said. “In the process of dealing with a diagnosis of mesothelioma and its impact on every aspect of their lives, these men and women learn for the first time that, not only could their past work have been the source of asbestos exposure, the dangers of such exposure were widely known among experts and industry since at least 1930
  • But rather than risk profits, workers were put at risk.” In addition to asbestos, Gary has experience litigating cases involving hydrofluoric acid, PAHs, crude oil wastes, TCE, vinyl chloride, styrene tars, creosote and silica
  • A Proven History of Success Before joining the firm, Gary served as of counsel at a Virginia firm while also managing his own Texas-based firm

  • Flores Texas decision requiring quantification of exposure. • Successfully defending asbestos experts in the first State of Georgia Daubert challenge hearing
