Jill Warren

Jill Warren is an attorney, business advisor, government affairs professional, and fitness entrepreneur.

Jill is Co-Founder and a Managing Director of The Passage Group, a business advisory firm that helps its clients build and grow their businesses using the levers of power in government. In Bloomberg’s 2024 review of advisory consulting firms, The Passage Group was named a “Top Performing Firm,” a “Standout Firm,” and the “3rd Fastest Growing Revenue Firm” in Washington, DC.

She is also the Managing Partner of Jill Warren & Associates, PLLC, a law firm devoted to prosecuting antitrust abuses in the pharmaceutical and healthcare industries. Jill was inspired to practice law by legendary Texas trial lawyer Joe Jamail, the original King of Torts, who generously mentored her while working at Jamail & Kolius in high school through law school. After clerking for the Texas First Court of Appeals, Jill practiced business litigation and appellate law at Akin Gump Strauss Hauer & Feld and Brobeck Phleger & Harrison, and government affairs at Bracewell & Giuliani. When US Senator John Cornyn (R-TX) served as Texas Attorney General, he appointed Jill to be Deputy Attorney General for Policy and Special Assistant Attorney General for Litigation. As Deputy AG for Policy, Jill was a member of the Executive Management Team, shaped state and federal policy for the 800-employee state agency and was the liaison between the State of Texas and the National Association of Attorneys General. As Special Assistant Attorney General, she represented the State of Texas in litigation matters, including legislative and congressional redistricting, Public Information Act prosecutions, and enforcement of the multi-billion-dollar tobacco industry settlement.

Jill is the CEO, President, and sole shareholder of Bar JW, Incorporated that created the largest collection of franchised Barre3 exercise studios in the United States — on the Georgetown waterfront in Northwest DC; near Union Station in Northeast DC; near American University in the Northwest DC neighborhood of Spring Valley; in Market Common Clarendon, Virginia; and in the DC Navy Yard, one of the fastest growing neighborhoods in America.

Originally from historic Huntsville, Texas, Jill attended the Cockrell School of Engineering at The University of Texas and is a graduate of The University of Texas McCombs School of Business and The University of Texas School of Law. She has run thirteen marathons; has summited Mount Kilimanjaro and climbed to Mount Everest Base Camp; has drilled and repaired water wells in the war-torn region of Darfur, Sudan; and is an aspiring helicopter pilot. Jill now works and lives on Lake LBJ in Horseshoe Bay, Texas and in the US Capitol, Washington, DC.
