Majority of Drupal vendors use Drupal for content management of websites they implement for their clients.
 
That does not require a deep understanding of how Drupal works - a competent web designer could put together a Drupal-powered website without needing to write a single line of PHP code.
 
That alone underlines the power of Drupal - imagine what a Drupal-trained web engineer could do - that's where we come in.
