Typically 10-16 people show up on a given night (members aren't in the habit of signing-up via meetup.com yet). You can attend as a guest and observe as many times as you would like. If you are feeling up to it, you may participate in the improvisational "Table Topics". Once you become an official member you can participate in the prepared speeches.
When: The 1st and 3rd Thursday of every month.
Meetings begin promptly at 7:30pm and typically run till 8:45pm.
Look for Entrance #2. Then go up the stairs and Rm 207 is to the right.
Annandale Toastmasters has been in existence since the 1960's. This is a neighborhood group with meeting times to fit people's work schedules. The group is diverse with members ranging from all walks of life, different ages, and speaking experience. The atmosphere is relaxed but still adheres to a typical toastmaster structure.
