Jason Heep is a litigation lawyer who focuses on counseling clients involved in environmental litigation, insurance coverage and bad faith disputes. He represents small companies to Fortune 50 giants, and he routinely advises them on environmental regulatory compliance issues, including CERCLA, the Clean Water Act, NEPA, and the Clean Air Act, reinsurance matters and risk management. Jason has extensive experience pursuing subrogation recoveries from the responsible parties who caused environmental contamination so that his clients are not left holding the bag.

Jason’s engineering experience translates into a shorter learning curve and greater comprehension of highly technical issues. Clients also value his ability to efficiently manage large, complex, multistate lawsuits and arbitrations. Jason and his team have a true national practice and are in state and federal courts from New York to California. The team also handles international and U.S. arbitrations.

Prior to joining Gardere, Jason was a judicial clerk for the Honorable Judge James C. Cacheris in the Eastern District of Virginia, and he worked as an associate at a major law firm in Washington, D.C. Before becoming an attorney, Jason worked as an environmental engineer for a national environmental consulting firm and served as a Peace Corps volunteer on Mt. Kilimanjaro, Tanzania.

Search Tips:

You may use the wildcard symbol (*) as a root expander.  A search for "anti*" will find not only "anti", but also "anti-trust", "antique", etc.

Entering two terms together in a search field will behave as though an "OR" is being used.  For example, entering "Antique Motorcars" as a Client Name search will find results with either word in the Client Name.


AND and OR may be used in a search.  Note: they must be capitalized, e.g., "Project AND Finance." 

The + and - sign operators may be used.  The + sign indicates that the term immediately following is required, while the - sign indicates to omit results that contain that term. E.g., "+real -estate" says results must have "real" but not "estate".

To perform an exact phrase search, surround your search phrase with quotation marks.  For example, "Project Finance".

Searches are not case sensitive.
