Just attended this workshop with my wife (description below). Pretty good overall. 

Main takeaways: Vary the tone of your voice. Be an engaged, attentive listener. Make sure you are interested and passionate in what you are talk about. After all, if you aren't interested in what you are talking about, why should anyone else be?

Description: This dynamic workshop will help improve the way you communicate by focusing on the nonverbal aspects of communication. Nonverbal communication can reinforce what you say, but when not used effectively, it can weaken your message. This workshop will focus on the techniques of expression, including gestures, body movements, positions and postures, the voice, breathing techniques, sustaining eye contact, the use of silence, and others.
