The Moment Everything Changed
Twenty minutes into a chaotic shift, a pediatric cardiac arrest hit our doors.
Monitors blaring. People talking over each other. Seconds loud enough to feel.
I stepped in, lowered my voice, and gave one clean instruction. The room snapped into focus.
That’s when I learned: clarity isn’t a luxury. It’s oxygen.
Away from the ER, I saw the same pattern in “normal” rooms—updates without decisions, louder voices without influence. I started treating words like instruments: sharp, specific, accountable. That became my operating system for leadership.
Who I am (and what I do now)
I’m Harry Karydes, DO—Emergency Physician, Certified High-Performance Coach, and executive communication specialist.
I help new leaders and healthcare executives build the Triple Threat: clarity, confidence, and credibility—so their message moves people and performance.
-
The craft: voice, writing, storytelling, slide logic.
-
The chemistry: presence, confidence, ethical power & influence.
My approach
I teach the how of delivery and the why behind influence—no theatrics, no manipulation. Think practical, ethical tools you can use in tomorrow’s meeting.
What Great Communication Really Requires
Craft
- Voice control: tone, pace, pause.
- Writing: one-page decision briefs, speeches, and memos that get read.
- Story: narrative spine, contrast, executive-ready slides.
Chemistry
- Presence: room command without volume.
- Influence: framing, objections, negotiation.
- Readiness: board Q&A, town halls, media, crises, difficult conversations.
Connection
- Understanding: goals, fears, incentives—speak to what matters.
- Listening: reflective loops, clarifying frames, say-back summaries
- Relationships: first impressions, follow-ups that create allies.
Ethic & Promise
Ethical influence only—no manipulation, no dark patterns. I treat power as stewardship: your words create clarity, protect people, and move work forward.
