Mehlman Castagnetti Rosen & Thomas
A partner at Mehlman Castagnetti Rosen & Thomas, Dean Rosen is one of Washington’s foremost experts on America’s complex health care system—and a master of both the politics and policies that shape it. He has more than two decades experience developing and advancing health policy initiatives on Capitol Hill and in the private sector.
Rosen advises a wide range of health care stakeholders, from established health system players to startups trying to gain a foothold in Washington, DC. He has represented health systems and hospitals, medical colleges and physician specialty organizations, health insurers, clinical laboratories, biopharmaceutical companies, nonprofit foundations and large national employers. He helps clients impact national policy and navigate the transformational health system changes taking place in the aftermath of the Affordable Care Act, and efforts to reform the ACA.
Prior to joining Mehlman Castagnetti, Rosen held a series of high-level positions in both the private sector and government, including on key committees in both the Senate and House. As the Chief Healthcare Advisor to then-Sen. Majority Leader Bill Frist (R-TN), a leading voice on national medical and health issues, he helped draft and navigate to final passage landmark legislation creating a Medicare prescription drug benefit. Rosen also helped pass patient safety legislation and laws in the wake of the September 11 and bioterrorism attacks in 2001 to ensure that local, state and national public health systems had new authorities and additional resources to respond to future threats.
Earlier, Rosen served as Staff Director for the Senate Subcommittee on Public Health, Majority Counsel for the House Ways and Means Health Subcommittee and Health Policy Coordinator for the Senate Committee on Labor and Human Resources (now the Senate Health, Education, Labor and Pensions Committee). While at Ways and Means, he played a leading role in crafting the Medicare provisions of the Balanced Budget Act of 1997. At Labor, he was the lead Senate staffer in drafting the Health Insurance Portability and Accountability Act of 1996 (HIPAA).
Rosen’s policy, legal and management experience ranges beyond Capitol Hill. He served as Senior Vice President of Policy and General Counsel for the Health Insurance Association of America (HIAA), and practiced law at Dow, Lohnes and Albertson in Washington, DC.
