Leadership and Contracting Organization

Current as of August 25, 2026 • Acting Commissioner: Kyle Diamantas (since May 12, 2026) • Sources: fda.gov leadership profiles (July 31, 2026) · OAGS page
← FDA profile
The most unsettled chart in this set. Commissioner Marty Makary resigned May 12, 2026; Kyle Diamantas is Acting, and the White House announced August 18 its intent to nominate Heidi Overton, MD (pending Senate confirmation, not yet on fda.gov). CDER and CBER are both on Acting directors, and CBER is on its 4th acting director and 6th leader since January 2025. The April 2025 RIF cut roughly 3,500 FTEs and eliminated nearly the whole Office of Digital Transformation executive team; the CIO seat is Acting. The stable island is the contracting shop: Leonard Grant has been the permanent HCA throughout.

Caveat on the OAGS division roster: the OAGS page is live but its content date is January 7, 2025, which predates the April 2025 RIF. Grant and Loube are corroborated by the HHS roster; the division directors below them may have changed without the page updating. We flag rather than guess.
