During these lessons you will learn some of the basics of the Estill Voice Model. Jo Estill began developing the model in the 1970’s and worked with many scientists, artists, and educators. She passed on her legacy two of her mentees--Kim Steinhaur and Mary McDonal Klimmet. They continue her work of teaching the model, advocating for new research and training teachers. In person voice training is the best way to go. You can take private lessons with an Estill teacher or you can go to a training. I am not yet certified by Estill International, but one of my teachers has encouraged me to teach.
