Narrator, The Long Road

Theo Marsh

Theo follows the years before the answer — the tests, the dismissals, the eventual name for it.

Leads The Long Road

Theo Marsh is the narrator of The Long Road and a house byline written and directed by our editorial team. He writes about diagnostic odysseys: the appointments that went nowhere, the symptom nobody could explain, the moment a name finally arrived. He is interested in how people keep going without an answer, and what changes when one comes.
