John Gilmour co-chairs the Environmental Litigation section.  His practice encompasses significant commercial, tort and environmental matters from coast to coast, including some of the largest contaminated sites in the country.

John represents public and private sector clients in environmental litigation and natural resource damages matters in both state and federal courts across the country.  John’s environmental focus predominantly has been contaminated groundwater, surface waterways and mining sites, including river systems degraded from years of industrialization/urbanization; chemical and weapons manufacturing processes; and mining operations.  He also handles complex commercial, tort and select IP matters for clients.  In every case, John works with the client throughout the representation to determine specific goals, whether it is early settlement, alternative dispute resolution, trial through verdict or other avenues to resolution.

A former multiyear Texas Super Lawyers “Rising Star,” John personally enjoys learning as much as possible about each of his client’s businesses and strategic goals in order to better meet their needs and serve their interests.  Clients value John’s creative analysis and dispute resolution strategies that consistently result in successful settlements and verdicts.  A trusted advisor, John is appreciated for demystifying the litigation process and aggressively defending his client’s rights at every turn, including at trial.  He regularly resolves multimillion-dollar disputes by focusing not only on what his client hopes to achieve, but also on what makes sense for them financially.

John began his litigation career clerking for one of the most well-known federal judges in Texas, Judge David Hittner, in the U.S. District Court for the Southern District of Texas.  He continues to put his trial skills to good use for his clients nearly two decades later.
