Former Deputy Associate Attorney General Mark Grider to Join Cadwalader

December 14, 2020

New Washington, D.C. partner has held senior roles in the Department of Justice and in the Office of the White House Counsel.

Cadwalader, Wickersham & Taft LLP announced today that former senior Justice Department official Mark A. Grider will join the firm as a partner in the Washington, DC office.

Grider has served across numerous administrations during his nearly 20 years in the federal government. He most recently served as a Deputy Associate Attorney General at the U.S. Justice Department, where his portfolio included criminal matters relating to the Antitrust Division, Civil Division, the Consumer Protection Branch, Environment and Natural Resources Division and the Tax Division. He is a subject matter expert on the False Claims Act, healthcare fraud, the opioid crisis, and competition and consumer harm in the online marketplace. Grider liaised on policy initiatives relating to elder fraud and financial exploitation, criminal antitrust procurement collusion and COVID-19 pandemic issues.

Prior to this role, Grider served as Senior Associate Counsel and Special Assistant to the President in the Office of the White House Counsel, advising White House Counsel and senior administration officials on broad oversight and regulatory matters involving the White House, Health and Human Services, and federal agencies, contributing special expertise on health care regulatory and litigation matters and science and technology oversight and policy issues. Between early 2019 and September 2020, he assisted on congressional oversight and investigations and coordinated responses to related litigation, FOIA requests, COVID-19 pandemic response matters, and Inspector General investigations.

Grider will lead Cadwalader’s Crisis Management and Congressional Investigations Practice.

“Mark is one of Washington’s leading lawyers,” said Cadwalader managing partner Pat Quinn. “He has been at the center of some of the most critical issues of the day and will bring a deep understanding of the complex legal and policy challenges facing public and private companies today.”

Added Cadwalader’s Jodi Avergun, who leads the firm’s White Collar Defense and Investigations practice, “Mark is a very significant addition to our Washington, national and transatlantic white collar government investigations capabilities. His experience with government advocacy and crisis management in a national setting is a perfect fit with our broad-based white collar practice. He will provide great insight and guidance to our clients in the areas of white-collar criminal defense, corporate internal investigations, Congressional investigations and strategic advocacy.”

Over a nearly 20-year career, Grider has held a number of other high-profile roles. After his tenure as a federal prosecutor in the Eastern District of Virginia, Grider moved to the DOJ’s Office of the Deputy Attorney General, where he served as Senior Counsel to the Deputy Attorney General and advised on operational and policy issues involving computer crime, intellectual property, health care fraud, pharmaceutical diversion, narcotics abuse and trafficking, death penalty review, and computer forensics matters. He also served as Special Counsel for Health Care Fraud and executive director of the DOJ’s Intellectual Property (IP) Task Force, where he developed strategic initiatives and metrics to monitor health care fraud, waste, and abuse efforts as well as corporate counterfeit and IP theft detection.

During the Obama administration, Grider served as a detailed special trial attorney in both the civil and criminal fraud sections of the Department of Justice, where he worked on false claims act matters, securities fraud, and international bribery and gratuities matters. 

Grider also has extensive congressional investigative experience on Capitol Hill in both the House and Senate. He was deputy general counsel for Chairman Trey Gowdy on the House Select Committee on Benghazi and was a staffer to former Senator John Ashcroft from Grider’s home state of Missouri.

Grider also served as the deputy general counsel to the Special Inspector General of Iraq Reconstruction, a role in which he oversaw civil and criminal litigation pertaining to procurement fraud and false claims act matters involving the more than $10 billion of government funds appropriated for Iraq reconstruction.

Grider rounds out his government experience with significant compliance roles at a national healthcare provider and was promoted to equity partner in private practice at a prominent Midwest law firm.  

“It is unusual to find someone who has deep expertise in so many areas of focus for our clients – and is so highly regarded by colleagues and peers,” said Cadwalader global litigation chair Jason Halper. “We know that Mark will be viewed as a significant addition to what is already a formidable white collar defense and investigations practice.”

Grider’s move to Cadwalader came on December 9.

“Cadwalader is held in such esteem in the business and financial communities and in Washington,” Grider said. “The firm has powerhouse capabilities and talent, in the white collar space and beyond. Because I see my greatest value to my clients as a business advisor and problem solver – someone who can build and lead teams assembled to address very specific challenges and needs – I look forward to bringing the power of the full Cadwalader legal team to bear on behalf of my clients.“

Grider has also been an important legal industry advocate for diversity and inclusion, and he plans to take on an active role as a member of the Cadwalader Center for Diversity & Inclusion.

“Diversity and inclusion efforts remain a top priority for all leading law firms and corporations,” Grider said. “Cadwalader is already a leader in ensuring opportunities for the recruitment, retention and promotion of diverse attorneys. I look forward to being a part of that concerted effort. I enjoy building talented, diverse teams to help all clients’ legal and business needs.”

Grider’s arrival follows a major announcement last week that a market-leading litigation team from Boies Schiller – led by renowned litigator Nicholas Gravante and including partners Philip Iovieno, Karen Dyer and Lawrence Brandman – is joining the firm. Grider, Gravante, Iovieno, Dyer and Brandman are important additions to a growing Global Litigation Group, which has grown with the recent additions in the past year of former Consumer Financial Protection Bureau senior counsel Rachel Rodman in Washington’s white collar practice; London white collar partners Mark Beardsworth and Kevin Roberts; State Attorneys General Practice head Doug Gansler, the former Maryland Attorney General; and a Boies Schiller civil litigation team comprised of Sean O’Shea, Michael Petrella and Amanda Devereux.
