The story of the Yellow Chair

When setting up the company, my choices were to use my own name or use something a bit abstract but with meaning. In coaching clients are working directly with me and so I wanted to choose something personal and with meaning that could stand for a represent me.


Then I remembered, when I was a child, before I went to school, we had this old painted yellow chair in the kitchen. I remember dragging that across the floor to stand on it, to be at the kitchen counter with my mum, so that I could ‘help’. I was probably a nuisance, but what I remember is playing, having fun, learning to read and reading books. It was a seat of learning, growth, joy and happiness. For me, when I work with clients I want them to learn and grow and to have fun. At times, it might be hard work, but it will always be fun. So that’s why I choose the yellowchair - it represents all of those things that gave me the right start to succeed and achieve in life.
