Annette Sessions, M.D.

Annette Sessions currently resides in Rochester, NY, where she is an Assistant Clinical Professor of Urology at the University of Rochester. During this tenure, she experienced the power and beauty of Worsley Five-Element Acupuncture® through the sharp end of the needle. In hopes of offering this medicine to her own patients, she studied this lineage of acupuncture through GLITCA, completing the requirements in 2009 and participating in the subsequent Master Apprentice Programs (MAP℠). She now practices both WFEA and urology through the University. Prior education included earning an A.B. in French at Duke University (1989), a M.A. through Middlebury College’s school in France (1990), and a M.D. at Vanderbilt University School of Medicine (1997).

Stella Jiang, R.TCM.P., R.N.

Stella’s interest in health of the body, mind and spirit led her to complete studies in Traditional Chinese Medicine (TCM)  at Shanghai Traditional Chinese Medicine University, China (2003). She is a registered TCM Practitioner, registered with College of Traditional Chinese Medicine Practitioners and Acupuncturists of British Columbia.  Subsequent studies with Qin Ma and Nora Franglen introduced her to Five-Element Acupuncture which she began practicing in 2019, and she found an enthusiasm for this form of medicine. In seeking to deepen her knowledge and understanding of it, she joined the Worsley Institute and pursued additional training through the WIT program in 2022.  Through this program, she truly developed a passion for the beauty and power of Worsley Five-Element Acupuncture.  She currently practices in two clinics in Vancouver BC and White Rock BC. 

In addition to being an acupuncturist, Stella is also a Registered Nurse specializing in Perinatal care and has been working in this capacity at BC Women's Hospital since 2010.

She is delighted to be a Board Member of the Worsley Institute, helping to preserve, protect, and promote the teachings of JR Worsley.
