I am Tiffany Mylastname Hislastname. I plan to teach, so it is not practical to ask kindergarteners to say a whole mouthful of names each time they address me.

I am Mrs. Hislastname at school. But, I am Tiffany Mylastname Hislastname officially.

I like it that way. It's traditional and a bit contemporary at the same time. It works for us.
