Public Speaking for Lawyers
Every year I teach a Public Speaking for Lawyers class. During that class the students complete a number of different presentations. Persuasive, informative, group, and impromptu scenarios are all covered.
A great way to improve your speaking is to watch or read great speeches. Thanks to the internet this has become a much easier task. With that in mind, I recommend American Rhetoric. It is a great site with over 5,000 of the greatest American speeches.
I actually feel that lawyers get a bad rap from the public. Everyone proclaim that they hate lawyers but when they need one they usually say that they like their attorney.
