My purpose at The Self-Expression Center is to support people to develop comfort and confidence to be authentic when they present, perform or communicate.  When you are authentic, you are your most clear, powerful and persuasive.

Whether you are a business professional, executive or speaker, you must engage the eyes, ears and hearts of others to be successful.  The sound of your voice can make the difference in whether people listen and respond to you or not. I teach the Lessac Method to help you develop your natural voice to resonate with the power and beauty of your authentic self. 

I also use Lessac voicework to help non-native speakers of English be clearly understood when speaking English.  It’s not important to lose your accent, but it is important to be easily understood when you speak English with your native accent.
