Nicknames or Preferred forms of names in a professional setting

 Hi Mark, Mike, Wendii and MT community,

I have a question regarding the use of nicknames, in my case an abridged form of my name, and the appropriateness of using it within a professional context. 

My given name is Andrew, but everyone (who knows me) has called me Drew since before I can remember. (As such, it's quite easy to identify sales calls on the phone.) However, my resume (business cards, etc) are still topped with "Andrew" out of a sense or notion that this is mandated, despite the fact that I only use my full name when legally obliged. I'm guessing that Mark and Mike may have similar experience.

Getting to my point, I would prefer to use 'Drew' as my professional name of sorts, but is it appropriate to do so?

It seems more effective and efficient than starting every interview or introduction by clarifying my name preference to the other party.

Are there any compelling reasons not to do this, other than the confusion of seeing my full name on a document of some kind and being temporarily confused?

Thanks in advance for your helpful advice and suggestions,

Drew R
