Dear all, change is hard. If you are coming to a completely different city for work, doubly so. We get you, it's terrifying, and there's seemingly a million things you need to take care of. But you're also excited, and you want this. I've been there, and I know how scary it is. You're going in completely blind. My hope is to make this transition at least a bit smoother for you.

I have been a summer intern, a post-master research associate, and am now a staff at ORNL. Throughout my beautiful years with ORNL, I learned a thing or two cause I've seen a thing or two (insert Farmer's insurance jingle here), and hopefully I can transfer my experience to make your transition smoother.

The goal of this rpeo is to be constantly iterated and become a living, evolving, central repository for new-to-ORNL people's survival guide. Please do comment and ask questions - I want to know what you want to know.
