Online Course:
How to communicate data via reporting and storytelling
Coming this fall in september 2025!
1
What is this course?
A practical online course for analysts, BI professionals, and consultants who want to design impactful dashboards and tell data stories that drive real decisions. Inspired by the timeless power of mythology and art, this course will turn you into the trusted data communicator every organization needs.
2
Why am I creating this?
I’ve spent years watching talented people get ignored. Dashboards were cluttered. Data stories fell flat. Opportunities slipped by. Data is power, but only if others understand it.
I created this course because I believe every analyst, BI pro, and consultant deserves to be heard, trusted, and remembered. This is the course I wish existed earlier: one that teaches you how to turn your data into influence & trust.

Your journey from invisible to influential
The course unfolds in five acts, like an ancient theater play, where each step brings you closer to becoming a trusted data communicator. Let the deus ex machina come.
ACT I: Why visualizations matter in this world
You’ll learn why most dashboards fail and why trust crumbles before a single number is read.
You’ll decode how perception works, why trust is your strongest weapon, and how data becomes dangerous when misunderstood.
ACT II: Become the interpreter with A.R.T.
You’ll guide the viewer’s focus.
Use structure and visual weight to shape what people notice—and what they don’t.
ACT III: Become the architect of action with N.O.V.A.
No more passive reporting.
You’ll design with intent, so every chart moves people forward.
ACT IV: Become the storyteller with data with M.U.S.E.
Facts alone don’t convince.
You’ll build tension, release insight, and leave a lasting message.
ACT V: Become the one people trust.
You’ll earn a new reputation.
Not as the person who shows the data, but the one who makes it matter.
