I had used Birkett Entertainment upon a recommendation from a good friend.  I held a non-profit gala at the Phoenix Convention Center and was surprised at how rude the office manager Denise was.  I was accused of asking too many questions - worse than a bride.  Questions like, what time is the DJ going to be there, Can the DJ talk to the Convention Center folks as they needed to ensure they had his needs met.  You see, the first DJ quit after I had many details settled, then trying to re-establish the details with the new D, it was met by Denise ultimately telling me never to use them again.  Although the new DJ showed up late and delayed the start, he was courteous and responded to my requests.   To all my friends and connections.  Never use these folks.
