Data can change the world, but humans tell the story. I’m passionate about helping people communicate better with data. The impact of a data project is rarely driven by the accuracy of the model, the elegance of the dashboard or the complexity of the analysis. It’s driven by how well insights are delivered to your stakeholders, and how effectively your stakeholders can leverage them. Great communication amplifies the impact of great insights. Whether you’re a data analyst, data scientist, a leader, or a combination of all three, you can have a bigger impact on your organization by improving how you share your projects. I teach how to structure your communications effectively, how to tailor your message to your audience, and how to use visualizations effectively. I have almost 15 years of experience delivering value from data through great analysis and clear communication. Today, I lead an analytics team at Marriott International, and help data professionals and aspiring data professionals improve how they talk about their work through my newsletter discussing communication techniques, and the Penguin Analytics YouTube channel, discussing how-tos for analysis, communication, Tableau, Power BI and more. If you love finding and delivering value from data, let’s connect!
