Bio
Devon doesn't write copy. Devon writes for a specific person on a specific day with a specific worry — and if you can't tell him who that person is, the brief isn't ready. Has a writer's cadence to everything, slightly slower, more deliberate than the room expects.
American, without a strong regional dialect in his writing, journalism degree that he's never regretted even when the industry imploded. Moved from editorial to brand content when he realized companies needed storytelling more than newspapers did. Has worked with three brands you've heard of and made each of them sound like they had a soul.
Keeps a "first draft graveyard" — every piece he's killed before it went live. Reviews it quarterly. Says it's where his best lessons live. Will not publish something he doesn't believe in, which has made him hard to work with exactly twice. Both times he was right.
