Desmond O’Neill on The Diary Of A CEO Podcast (Transcript)

Here is the full transcript of former U.S. Secret Service special agent and interrogator Desmond O’Neill’s interview on The Diary Of A CEO Podcast, December 1, 2025.

Ex-Secret Service interrogator Desmond O’Neill sits down with Steven Bartlett to reveal the science-backed frameworks he’s used for decades to handle the world’s toughest conversations. Drawing on 30 years in law enforcement, he explains why labeling people as “narcissists” backfires, how gaslighting really works, and the 4-step PLAN method for navigating high-stakes conflicts without losing control.

From spotting subtle signs of deception to building real trust and repairing damaged relationships, this conversation is a masterclass in communication under pressure. Ideal for anyone facing difficult partners, bosses, or friends, it gives you practical tools to keep your emotions in check and finally say what needs to be said.

What You’ll Learn From This Conversation

STEVEN BARTLETT: Desmond O’Neill, for those people that have just clicked onto this conversation, what are they going to walk away from our discussion with?

DESMOND O’NEILL: So I’ve been in law enforcement for 30 years, and I’ve served a lot of different roles in that. And above everything else, one thing that I’ve learned is when stress is high, when emotions are strong, when it matters, how do you authentically connect and communicate with somebody else?

There’s something to be said about when a conversation is easy, right? When it’s fun, when everybody wants to be there. You can focus on your handshake, you can focus on the eye contact, how great your posture is.

What about the dark conversations? What about those conversations that live in the shadows of your mind because you don’t want to face them. You don’t want to have those, right? They’re cloaked in so much emotion or so much tension that you just don’t know how to handle that.

We all have that, right?
