Reese Marketos is thrilled to announce Allison Cook as its newest partner. Cook joined RM’s partnership effective Jan. 1, 2026.
Cook represents clients in high-stakes litigation, specializing in whistleblower-side False Claims Act litigation in matters focused on healthcare fraud, defense procurement fraud, and cybersecurity fraud. Separately, she represents whistleblowers who submit securities-fraud tips to the U.S. Securities & Exchange Commission through its SEC Whistleblower Program. Cook also represents companies and individuals on both sides of the “v” in a wide array of high-stakes complex commercial litigation, including breach of contract, tortious interference, defamation, and fraud.
RM founding partner Pete Marketos said the firm’s decision to promote Cook was easy.
“Allison embodies our firm’s spirit: entrepreneurial, collaborative, selfless, endlessly positive, and relentless in pursuit of justice for our clients,” Marketos said. “She leads by example, is respected by colleagues and opponents for her deep knowledge of the False Claims Act and commercial practice, and she has a moral compass that always points due north. We are lucky to have her.”
Cook joined the firm in 2021 after clerking for the Hon. Karen Gren Scholer in the U.S. District Court for the Northern District of Texas. Before that, she spent several years practicing at a large law firm in Dallas. Within three months of joining Reese Marketos, she played an instrumental role in a three-person trial team that won a $36 million False Claims Act jury verdict against a military defense contractor in Alabama federal court.
“Allison’s commitment to her clients, curiosity, intelligence, and sense of humor make her a first-class colleague and advocate,” said RM partner Josh Russ, who leads the firm’s False Claims Act practice. “Her depth of knowledge and experience in False Claims Act litigation separates her from her peers and has garnered her national recognition. Allison’s future is incredibly bright, and I am proud to call her my partner.”
Cook earned her bachelor’s degree in government at The University of Texas at Austin, graduating with highest honors. For law school, Cook attended Southern Methodist University’s Dedman School of Law, where she served as editor-in-chief of the SMU Law Review and graduated as valedictorian.
