This is one of about a hundred or so Whitepapers, documents, and sell-sheets I did for a consulting and marketing company. They came to me as a Word file, and a Powerpoint file. That material then had to be edited and layed out according to the VERY strict and voluminous corporate style guide.
These are two examples of the sorts of work I did for Quest Diagnostics. Quest had a very rigorous style guide that was always being modified. Some of these were being updated to match the current style guide, some to update data, price lists, or newly available services.
