I’m Dr Peter Clayton (please just call me “Peter”) and with over 20 years of experience in Excel consulting and international management, having worked with more than 750 clients on over 2,000 projects in various industries, I am keen to share my knowledge and expertise. If your goal is to harness Excel for better strategic decision-making, improve business operations, or advance your career, you’ve come to the right place for your own personal Excel tutor, coach and mentor.

My Excel Journey

Excel Tutor UK

My adventure with Excel began in the early stages of my career when I quickly recognized the immense potential of this powerful tool in transforming business operations, strategic decision-making, and data analysis. After working in IT project management for Procter & Gamble I set up my own software company then trained Business Studies students in Excel at a local university. I then developed my Excel skills as a manager and consultant running international election operations for the United Nations and similar organisations round the world. I eventually chose to set up my Excel consultancy business for the last 17 years and have continued helping companies and their staff use Excel to improve their efficiency and profits through building Excel spreadsheets and training staff to build them themselves. I have personally trained and tutored hundreds of people to improve their own skills and careers.

Over the years, I have worked with more than 750 clients, contributing to over 2,000 projects across a broad spectrum of industries. This extensive experience has not only deepened my expertise in Excel but also allowed me to understand the diverse needs of professionals at different stages of their careers and within various sectors.
