I'm not going to speak about my current DON, but one of the best I ever had.
She had the ability to recognize each person's unique talent, and to put that to use to form a very good team.
For instance, I'm a people person, so if she got a particularly difficult family or patient, she'd assign them to me - I could usually manage to keep everyone satisfied without being a pushover.
Another nurse was super organized, so she usually worked on the schedules.
And so forth.
This lady never asked us to do something that she wouldn't do, and in a crisis, she'd be in there working along side. Her skills were fantastic, but she didn't insist that everything had to be done 'her way'.
She never critisized anyone 'in a crowd'. She was like a bear if she thought any of the doc's were trying to abuse one of us - and most of them were a little in fear of her!
