Professor McGill is a brilliant clinician. After a disc herniation and a year of pain and sciatica, he identified my issue and explained it in straightforward language. As an opera singer, my back, lungs and core are the keys to my vocal power and stamina. Professor McGill helped me to practice better mechanics both in singing and in life while also creating a training program. He helped get me back onstage, singing and moving freely and painlessly. I’ve recommended ‘Back Mechanic’ to singers, instrumentalists and coaches, too. Grazie, Professor!
