DISC Personality Types & Assessment

Estimated reading time: 3 minutes

The DISC personality types model is one of the best tools for understanding yourself, your colleagues, and your prospects. Most people lean into one of the four core styles: Dominance (D), Influence (I), Steadiness (S), or Conscientiousness (C). A lot of people show a blend of two, like a D with secondary I traits (a DI), or a calm, steady SC.

Your DISC personality type shapes how you communicate, think, decide, and close. It’s not theory. It’s pattern recognition. And once you can read it on a sales call, everything changes.

Most salespeople lose deals because they sell in their style instead of the prospect’s. A high-D doesn’t want your 20-slide walkthrough. A high-S doesn’t want to be rushed. Match the style and you stop forcing your default on everyone. You start becoming someone they trust.

What’s Thomas’ DISC?

I’m a high DI! My dot’s so high it’s redefining the edges of the circle.

This means I move fast, speak directly, and lead with a lot of energy. I’ve also had to learn when to pause, listen, and to dial it back when needed.
