From Wikipedia, the free encyclopedia
Toastmasters International (TI) is a nonprofit educational organization that operates clubs worldwide for the purpose of helping members improve their communication, public speaking and leadership skills. Through its thousands of member clubs, Toastmasters International offers a program of communication and leadership projects designed to help men and women learn the arts of speaking, listening, and thinking.
The organization grew out of a single club, Smedley Club Number 1, which would become the first Toastmasters club. It was founded by Ralph C. Smedley on October 22, 1924, at the YMCA in Santa Ana, California, United States. Toastmasters International was incorporated under California law on December 19, 1932. Throughout its history, Toastmasters has served over four million people, and today the organization serves over 260,000 members in 113 countries, through its over 12,800 member clubs.
