This. I discovered Toastmasters about a year ago and it's done wonders for my confidence about speaking. I wish somebody had told me about it five years ago.

If you're at a largish company they may even have their own internal Toastmasters club, which is a great way to get involved without having to venture far outside your comfort zone.

I'm president of local Toastmasters club in SF - I strongly agree with this comment ;).

But seriously, it's a very supportive environment and you get great, actionable feedback on every speech. Really fast way to develop yourself.

Tried to attend my first Toastmasters last night and they didn't show up!

Another +1 for Toastmasters.

I've gotten a lot more comfortable speaking in front of people.
