On April 1, 2026, China implemented a landmark national standard: Classification and Determination of TCM Constitution. Although designated as a recommended rather than mandatory standard, it represents a major step in modernizing traditional Chinese medicine (TCM) by converting traditional constitution theory into a clear, measurable and clinically practical framework. By clarifying the relationship between constitution, disease, and pattern differentiation, the standard strengthens professional credibility, supports research, and enhances patient-centered treatment.
William Prange, BA, BS, MA, OMD
Dr. William Prange pioneered the use of acupuncture in mainstream medicine while providing over 100,000 unique patient visits. His TCM studies began before California first approved schools in 1976. As a psychotherapist specializing in mindfulness-based somatic therapy, he earned a degree in advanced acupuncture studies in China (1982) and an OMD addressing complex biao-li conditions from SAMRA (1984).
He served on the first of California Acupuncture Association’s advisory boards while founding the Sonoma Oriental Medical Association and building a successful integrative practice with MD partners. He was also the first acupuncturist to obtain hospital privileges in California (1997), and subsequently helped launch integrative programs for Sonoma County’s Kaiser Permanente, Sutter Hospital, Blue Shield of California, and American Whole Health.
Always dedicated to the health of his patients, he blended acupuncture with bodywork, herbal therapies, effective listening, and proper referral. He is now retired on the central coast of California, where he teaches meditation and looks forward to supporting the further development of our profession.
