David began his professional life as a qualified building architect in the UK, but found the challenge of linking information to drawings too exciting. He gave up architecture in the late 80s to follow his interest and became a developer and consultant on facilities and cable management software. In 1996, David began to use Visio linked to enterprise databases, and in 1998 started his own data visualization consultancy business, bVisual ltd. His Visio-based solutions have extended to include project management, risk analysis, and process flows, amongst other things.David has been a speaker at several Visio conferences over the years, and has been awarded Most Valued Professional status for his services to the Visio community for the last five years. He writes a regular Visio developer blog, and has previously authored a book about visualizing information with Visio 2007.
