COM is an evolving, dynamic system of diagnosis and treatment that draws upon Dr. Hammer’s more than sixty years of experience in both allopathic Western medicine and East Asian medicine. His knowledge, together with the wisdom of his mentor, Dr. John H. F. Shen, is an invaluable resource to practitioners and students alike wishing to deepen their understanding of the true nature of health and healing.

Through the COM Foundation and its community of teachers, practitioners, and students, this knowledge is now available to healthcare professionals and members of the public.

Here on our website, you will find…

…an extensive library of publications, articles, essays, and excerpts from Dr. Hammer’s published and unpublished works. We also feature a current blog containing quick reads and postings from some of COM’s certified instructors and current students, as well as a listing of community events and classes related to COM.
