Carl has changed my voice completely within the past year. He made me aware of how much voice I hadn't accessed in my singing and how there was a lot more richness, fullness, and depth that should and could be accessed altogether. He made this happen slowly and helped lower and stabilize the larynx. His teaching style is old fashioned, well thought out and the singing is based off of a perfection of the individual's speaking voice. Without the proper training and attention to detail, I would have continued to sing in the same manner and the approach to my high notes or as us tenors say, 'our money notes', would still have been incorrect and perhaps in time, nonexistent. He is wonderful, knowledgeable and inspirational. I am lucky to have met him and that the timeline of events happened the way they did. He is, by far, the greatest teacher I have worked with..... this is why I make it a point to fly into Chicago from Toronto every two months. He is well worth the time.
