Excel, Power BI and AI training that sticks
Live, small-group courses for professionals and teams, taught online by a qualified teacher and data analyst.
Practical from day one
Every session uses realistic business examples, so you can apply what you learn at work straight away.
Small groups, real support
With four to six learners per group, your questions get answered and nobody gets left behind.
Better decisions, less stress
Spend less time wrestling with spreadsheets and more time understanding what your numbers are telling you.
Courses for every stage
I run five live online courses: Excel Intermediate, Excel Advanced, Power BI Foundations, Power BI Intermediate and AI in the Workplace. Each runs for 2 hours a week on Microsoft Teams, with no more than six learners per group.
Meet your tutor
I’m David, a qualified maths teacher and former Head of Maths who moved into data analysis and technical training. I now train data apprentices and professionals in Excel, Power BI, SQL, Python and AI. My aim is simple: make data feel manageable, one clear step at a time.
Training for your team
Need something tailored? I run private sessions for teams, built around your own data, your reports and the AI tools you use.
