Are there any schools with specific programs for folks who want to be a td?
Have you seen TDCollege? Haven't attended there, but it seems pretty nice. Experienced instructors. Unless you're against the whole online school thing...

They are a bit expensive I think. But may be worth checking out if you can afford.
I looked at TDCollege. They are kinda pricey, but it does look like a good setup. I don't mind online classes, my concerns are money and help with placement once I finish a program.
What about Gnomon? If you want a cheaper alternative, then you should check out the Vizlab at Texas A&M.
