Sharp wit, real warmth
Funny when it lands, genuine the rest of the time. The room relaxes because he's clearly enjoying it too, and a relaxed room gives your speakers a much better day.
Nothing rattles him
Runs late, speaker's a no-show, tech dies, someone's had a few too many. He rolls with it and the audience never sees the seam. CSIRO keep him on call to parachute into rooms at short notice for exactly this reason.
Panels worth staying for
Real questions, answers that go somewhere, and a gentle handle on the one panellist who won't stop talking. Eighteen years of facilitation is why this bit is easy for him.
The audience feels held
They know where they are, where they're going, and that somebody's got the day. That's the whole job, and it's the bit most people notice only when it's missing.
