Group Speaking Training to Improve Public Speaking & Presentation Skills – Course

Do you freeze up, tense up when you speak to groups?
Can you share your ideas and expertise easily in meetings?
If you could speak from your heart in groups and presentations, how would it transform your life?

We facilitate a nurturing process to build good communication skills where you discover your natural abilities to speak authentically in groups, meetings and presentations.

Our presentation skill and group public speaking classes and programs offer a step-by-step approach to develop a style of speaking that is based on being who you are, rather than who you think you should be.

Our Zimmer Method approach to speaking in public is different from traditional approaches. We don't just teach mechanical speaking skills or provide a public speaking tip. We free you up to be present, comfortable and genuine in front of others. You learn to show up with a powerful and authentic presence that frees your self-expression, so you improve public speaking significantly.

In a supportive environment, we guide you to relax and open up to public speaking from your authentic and most brilliant self. You learn to flow your thoughts and words freely and to speak from passion. Most participants tell us that this is just what they needed to develop their confidence and build better communication skills. Our group speaking programs include:

“I had to speak in front of about 30 people that were very high ranking in my company and I was applauded. I went around the room prior to speaking and shook hands with each person which helped me to connect with each one of them. That helped me out greatly in my speaking. I feel so wonderful about the experience now and feel like I can move on to do more things. Thanks!!! ”

“Sandra, please accept my joy and excitement “the day after“ your weekend Turning stage fright into Dynamic Presence workshop. It was everything I was looking for and more. You have found a way to make it possible for me to find and be with the power that I have. Part way through the workshop I began to feel a presence or strength in my upper abdomen that is still with me. It's solid like a rod or column of a building that supports me, but also has a pure energy quality to it. This presence will be a constant reminder that I can and do connect with others in powerful ways.”
