“The Trager Approach” as it is more generally known, is the discovery of Milton Trager M.D.who first encountered its principles somewhat serendipitously, at the age of 18. He then spent the next 50 years, as a lay practitioner and later, medical doctor, refining and expanding his discovery. With a long and successful career as a therapist behind him, Milton Trager embarked on the new venture of teaching his work at an age when most others are thinking of retirement. There are now thousands of Certified Practitioners throughout the globe; in the United States, Canada, Europe, Australia, and Japan. At the age of 88, he passed away in January 1997 – after teaching for over 20 years.
