This article provides a statistical accounting of the state of osteopathic medicine in Pennsylvania on January 3, 1959. How far we’ve come in 66 years! The state is now divided into 13 districts rather than 9. More than 10,000 DOs practice in the state of Pennsylvania, rather than just over 1,300 in 1959. Perhaps most telling of the growth of our profession, in 1959, there were only 6 osteopathic medical schools in the United States (the Philadelphia College of Osteopathic Medicine being one). Now, we have three medical schools with four campuses in the state alone, with a fourth school preparing to accept its first class in 2026. With a 70% increase in the number of osteopathic physicians in the country in the last decade, Pennsylvania continues to be an integral part in the growth of the profession.
