In a world of odd “spiritual” beliefs, Dr. Casey Means is no outsider. In fact, she is an effective channel for them.

Means and her brother, Calley, are Stanford-educated medical professionals whose work focuses on functional medicine — the sort of root-cause and wellness interests that drive the “Make America Healthy Again” movement. The siblings act as healthcare lobbyists and, more specifically, top advisers to Health and Human Services Secretary Robert F. Kennedy Jr. Their objectives have come to represent a broad view of the conservative-Christian position on matters of health.
