Dennis's passion for creativity and innovation led him to found Silver Bullet in 2001.
Dennis's education was as a scientist, reading physics at Clare College, Cambridge, followed by taking an MPhil at the Department of Molecular Biophysics and Biochemistry at Yale University, and a PhD in biology at the University of California at San Diego. Dennis is also a Sloan Fellow, with distinction, of London Business School. Dennis's scientific heritage has influenced his work ever since: Dennis's
approach to creativity is disciplined and highly analytical, and in no way 'fluffy'!
On returning to the UK from California, Dennis decided to leave academia, and joined Deloitte Haskins + Sells as a trainee IT consultant, a firm in which Dennis spent 18 years, including through the merger in the UK with Coopers & Lybrand. For 12 of those years, Dennis was a consulting partner, during which time, amongst many other things, Dennis was a pioneer of business and financial modelling, and founded a centre of excellence in the use of mathematics and statistics in business - a group which still exists to this day (after mergers with Price Waterhouse and sale to IBM) as the Advanced Analytics group at IBM. Dennis was also the firm's client-handling partner for the then-largest consulting clients, the London Stock Exchange, National Grid plc, and, during the privatisation of the water industry in England and Wales, the Department of the Environment.
Dennis resigned his partnership to become an Executive Director with Goldman Sachs, taking up the role of Head of Management Controls (Europe), responsible for internal audit and internal consulting in London, Paris, Frankfurt, Zurich and Milan. Subsequently, Dennis was appointed Managing Director of the UK operations of SRI Consulting.
Dennis is an accomplished public speaker, and has appeared on the platform of many conferences; he has written many articles, for journals such as London Business School's Business Strategy Review, Management Today, Accountancy and Accountancy Age; Dennis is also the author of eleven books, including Unlock Your Mind, Smart Things to Know about Innovation and Creativity, Creating an Innovative Culture, and Seeing the Forest for the Trees - A manager's guide to applying systems thinking.
