The NIH Executive Secretariat (Exec Sec) is an organization within the Immediate Office of the Director that provides expert support to the NIH Director and Principal Deputy Director, ensuring timely, accurate, and fully integrated response and decision-making information. Exec Sec represents NIH’s perspective to HHS Operating and Staff Divisions and other government agencies, and serves as an honest broker in adjudicating differences in organizational perspectives across NIH. This work is often accomplished in collaboration with a network of liaisons in NIH’s Institutes, Centers, and Offices.
