Whether on paper or in the courtroom, Marcos Rosales loves telling his clients’ stories.

He represents individuals and businesses in all types of complex civil litigation with a breadth of experience in oil and gas disputes, catastrophic personal injury and wrongful death litigation, professional negligence matters, shareholder and securities disputes, director and officer liability, and trusts and estates litigation. Having previously served as senior vice president and general counsel of a diversified holding company with operations in multiple industries, Marcos employs his real-world business experience along with his engineering training and attention to detail to advocate for his clients.

Marcos’s love for advocacy extends beyond the courtroom, too. He serves on the board of directors of the Houston Urban Debate League, an organization that has worked to make the academic activity of debate available to students in Houston’s urban high schools with the end goal of getting students into and out of college with degrees. Closer to home, Marcos also serves on the Leadership Council of Texas A&M University’s Association of Former Students.
