“I worked with Steve on a large awards event for the young science community. Steve engaged with the audience perfectly, delivered a continuously high level of energy, enthused the audience and did it all with a great sense of humour. Great guy to work with and won’t hesitate to use him again in the future.” – 
“A brilliant presentation, easy to follow and understand and very engaging but really quite original. Would definitely take students to see again. –
