Mary joined the Firm in 2005 and has more than 36 years of experience in the environmental arena, focusing on environmental litigation, enforcement, remediation, compliance, counseling, transactional and permitting matters.

She regularly represents clients in administrative and civil enforcement cases before the Environmental Protection Agency (EPA), Texas Commission on Environmental Quality (TCEQ) and State Office of Administrative Hearings (SOAH). Many of Mary’s clients recognize that her strong working relationships with each of these agencies allows complicated processes to move forward more quickly.

Mary also represents potentially responsible parties and landowners in environmental lawsuits including bankruptcy matters, toxic tort, property claims and suits brought under various environmental acts including Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Resource Conservation and Recovery Act (RCRA), Oil Pollution Act (OPA), Clean Water Act (CWA), Clean Air Act (CAA) and comparable state statutes.

Mary’s clients appreciate that no matter how complex a situation may be, she has the ability to immediately clarify and narrow the primary deal issues so they can be adequately resolved. This, in turn, enables her to quickly address the more minor stumbling blocks in a given case.
