Making GIS, Data, and Excel Finally Make Sense 😊

David G.

I’m a data and sustainability professional with a master’s degree in Climate Change & Society from NC State University and a background in environmental data analysis, GIS, and Python programming. I’ve worked as a Climate Risk Analyst at the U.S. Environmental Protection Agency and as a Senior Sustainability Data Analyst at a Fortune 500 company, where I built tools to simplify complex datasets and make insights clear to non-technical audiences.

I love helping students bridge that same gap—turning confusion into clarity. Whether it’s GIS, Python, R, Power BI, or Excel, I focus on making the logic behind the tools click instead of just memorizing steps. I’ve tutored college students and early-career professionals, often those who felt intimidated by technical material. My sessions are conversational and practical: we work through real examples, talk about why things work the way they do, and build confidence with repetition and small wins.

I know what it’s like to struggle with technical subjects (I didn’t start as a “math person” myself), so I emphasize patience, clear explanations, and connecting each concept back to real-world use cases—especially in environmental and sustainability contexts.

If you’re looking for help with GIS, data analytics, climate metrics, or just getting more comfortable with data tools in general, I’d be glad to help you find your footing and start feeling confident in your skills.
