This is an organization founded by Lee Glickstein, creator of the SPEAKING CIRCLES© methodology for building speaking confidence. I highly recommend his approach and his book, Be Heard Now.
A great resource for experts who speak professionally, or want to. NSA is a great place to learn about both the art and the business of professional speaking.
Helpful compilations of ideas gathered from subscribers/contributors who are professional speakers.
Worldwide organization to encourage public speaking practice and skill. I have mixed feelings about Toastmasters. Practice is a good thing, but in my opinion, Toastmasters puts too much emphasis on mechanics and not enough on authenticity and connection. The tone and type of support can differ dramatically from one club to another so if you are considering Toastmasters I highly recommend that you shop around for a club in which you will feel supported and not nit-picked to death. If you were uncomfortable with a Toastmasters experience in the past, the SPEAKING CIRCLES© approach mentioned above might be a better fit.
