About Trajan

Trajan Perez focuses his practice on litigation and environmental issues, whether commercial or regulatory, and is committed to saving clients time and costs to ensure success and long-term viability. His breadth of experience includes issues spanning environmental liability, toxic tort claims, products liability, establishing and maintaining federal and state regulatory compliance, and brownfield redevelopment issues, as well as handling sophisticated contract and commercial disputes. Trajan represents manufacturers, energy companies, industrial facilities, waste and recycling entities, and other highly regulated businesses. He is known to take his clients’ problems as his own, which is reflected in his acute knowledge of their businesses and adjacent sectors and industries, as well as a robust understanding of the regulations that govern their operations.

The difficulty of doing business in California, where wage and hour claims are commonplace, requires California-specific experience and insight on employment issues. Trajan has represented California entities in workplace and personnel-related disputes, including defense against discrimination and harassment claims, PAGA claims, employee disputes, and wage and hour claims.

Trajan represents large multinational entities with growing and interconnected challenges, risks, and opportunities. In both administrative hearings and in trial, Trajan represents clients against local and state agencies to successfully resolve municipal challenges and/or disputes. On the environmental side, he litigates federal cases arising under CERCLA and RCRA Superfund statutes, handling all aspects of the litigation process, including negotiations with responsible parties, contribution and allocation remedies, and cost recovery. He advises on matters concerning federal regulations, including the Petroleum Marketing Practices Act, the Clean Water Act, and the Clean Air Act, as well as various state-law equivalents. Additionally, he advises on and negotiates with state and federal environmental agencies, obtaining environmental permits, and manages environmental response activities. He is familiar with all aspects of ADR and has recently begun to offer his services as a mediator. Trajan is also experienced with admiralty and maritime law, including arrests and attachments.

Trajan maintains a reputation for his litigation practice, overseeing and advising on complex litigation strategies. He leads teams of attorneys in multistate and multidistrict litigation to achieve clients’ objectives. From high stakes matters to high volume and multijurisdictional issues, Trajan is called on to assist general counsel with their legal project management needs. With intimate knowledge of his clients’ in-house structures, Trajan develops project management processes with the goal of better predictability and reducing costs for clients. As circumstances change or facts become known, effective project management allows for monitoring, limits unapproved deviation, and creates opportunities to pivot accordingly.

In the legal profession, Trajan is a leader, collaborator, and mentor. He leads the energy and shipping department with attorneys spanning offices in California, Oregon, and Washington. He has earned several prestigious accolades, including “Leader in Their Field” by Chambers USA.
