Visual Thinking Masterclass
How visuals actually work, and how to build them in PowerPoint. The fastest way to understand what I teach.
Make evaluations easy to understand
I'm Sara Vaca. I teach evaluators, researchers and humanitarian teams to turn dense findings into visuals that land — using only PowerPoint.

The problem
Tired that nobody reads your reports?
You spent three months on that report. The messages are solid. And still — the executive summary gets skimmed, the recommendations get lost, and nothing changes.
It's not your work. It's how you present it.
Reports, evaluations and frameworks — redesigned so people actually read them.
This is for you if you're:
01
An evaluator or researcher whose reports deserve a wider audience
02
A humanitarian or philanthropy professional presenting to donors and boards
03
Anyone who has to explain something complex to people with 4 minutes and no patience
No design background needed. No new software. Just PowerPoint. And your brain.

Clarity is a skill. I love teaching it. Start here: three free tools.
② With Michael Quinn Patton
The Periodic Table of Evaluation 2.0
The whole evaluation discipline on one page, with a glossary to navigate it. New: now also organised by frameworks, and you get both versions.
③ Template
Desk Review Mapping Tool
A template to map and synthesise your document review — visually, from the start.
In good company
Fifteen years sharing clarity.
I've trained teams and worked with 23 organisations across 30 countries.
Who is behind this
I make evaluation clearer. And your messages stand out.
For fifteen years I've designed evaluations and visualised them — for UN agencies, NGOs and foundations across 30 countries. Every technique I teach is one I use on real assignments, the week I teach it.

Voices from the field
Clarity, in their own words.
“Clearly this is the era of visual communication, whether you are communicating a model, findings, or an approach. And Sara Vaca is my expert and go-to resource.”
Michael Quinn Patton
Founder of Utilization-Focused Evaluation · co-author of the Periodic Table
Noticeably more useful work.
“I picked up several practical strategies that made my work products noticeably more useful for the audience. The setup and content were beneficial straight away, and Sara's accommodating style made the whole process smooth and enjoyable.”
Cheryl Abram
Founder, Ypifany
Two ToC sessions, two countries.
“A very good course. It shows you practically how to build a theory of change visually, and gives real tips for facilitating a session with project teams. Thanks to it, I facilitated two theory of change sessions with teams from two different countries. Highly recommended.”
Bianca Tejada
M&E Analyst, UNDP
A clear framework, plus practical tools.
“I learned a lot. Beyond a clear framework for understanding the purpose, content levels and elements of a Theory of Change, it gives you practical tools for facilitating collaborative design processes.”
