of TCM Origin
Dr. Leon I. Hammer, M.D. has had a remarkable life and career. He has a wonderful ability to think independently of establishment constructs, and because of this has made invaluable contributions to the world of medicine and healing. Born in 1924 in New York City, he served in the United States military during and after World War Two as a Navigator, Aerial Gunner, Captain and Physician. He attended Cornell University and Cornell Medical College, and then went on to study at the William A. White Institute of Psychoanalysis and Psychiatry.
Until 1971, he practiced psychiatry and psychoanalysis, directed a child guidance clinic and Drug Abuse Councils on the Southeast Shore of Long Island, taught at Adelphi University, and was Psychiatric Consultant and Associate Professor at Southampton College in Southampton, New York.
After working with Fritz Perls and Gestalt therapy for three years and with Alexander Lowen and Bioenergetics over a period of eight years, he began a study of Chinese medicine in 1971. For the next three years, he studied in England with Dr. J.D. van Buren.
In 1974, he began a twenty-seven year-long apprenticeship with a Chinese Master in New York City, Dr. John H.F. Shen. During this time, Dr. Hammer spent four months studying in Beijing, China. His study and work with Dr. Shen had a huge influence on his work, eventually leading him to develop what has become Contemporary Oriental Medicine.
In 1975, Dr. Hammer achieved certification to practice acupuncture in New York State and later also became a registered acupuncturist in Maryland, where he studied and taught at the Traditional Acupuncture Institute. In 1985 he was granted honorary ‘Diplomate in Acupuncture’ status by the NCCA.
Dr. Hammer has practiced Chinese medicine since 1973. He has lectured and taught in places as diverse as Spain, Poland, Italy, Holland, Germany, England, Australia, and Japan, as well as all over the United States. He served as a member of the Commission for Evaluation of Acupuncture Schools and was appointed a member of the National Blue Ribbon Committee for Initiation of the Herbal Examination. From 1991 through 1998, he was a member of the New York State Board of Acupuncture. In 2001, Dr. Hammer received an award as “Educator of the Year” for participation and contribution to excellence in education from the American Association of Oriental Medicine. In 2002, he received an award from the Traditional Chinese Medicine Foundation for “Building Bridges of Integration” between Oriental medicine and Western Medicine.
In April 2001, Dr. Hammer helped found Dragon Rises College of Oriental Medicine in Gainesville, Florida. He served as Chairman of the Board and as a faculty member, offering direction and guidance to students and practitioners. The school is distinguished not only by its strong focus on diagnosis, especially Contemporary Chinese pulse, but also by its curriculum, Contemporary Oriental Medicine. COM stresses psychology, along with a methodology for thinking in Chinese medicine, and integrates parts of various models including TCM and Five-Element into a unique whole. The College is accredited by the National Accreditation Commission for Acupuncture and Oriental medicine and licensed by the state of Florida to grant Master’s degrees in acupuncture and Oriental Medicine.
Dr. Hammer was first published on the subject of Chinese medicine in the American Journal of Acupuncture in 1980 and subsequently has written numerous articles on a range of subjects within the medical field. His first book, Dragon Rises, Red Bird Flies (Eastland Press, 1990) was also translated and published in Germany and Spain and has become a classic in the field. His second book, Chinese Pulse Diagnosis, A Contemporary Approach (Eastland Press, 2001), has been described as a seminal work. In 2008 his third book was published: The Patient-Practitioner Relationship in Acupuncture (Thieme). He has written a compendium of the herbal formulae of Dr. John H.F. Shen (Thieme, 2012, with Hamilton Rotte), and, most recently, Eastland Press published Dr. Hammer’s The Handbook of Contemporary Chinese Pulse Diagnosis (2012).
He has a great love of nature and ecology, and a passion for ensuring that all creatures are treated with equal respect and compassion. Dr. Hammer greatly enjoys sailing, kayaking, cross-country skiing, and tennis, although sometimes he is happiest just sitting and watching the birds, trees and mountains from his window. He is married with children and grandchildren and currently lives in Florida.
Dr. Johanna Yen is the founder and President of the Atlantic Institute of Oriental Medicine (ATOM), the only Traditional Chinese Medicine College in Broward County. She was a Medical Doctor in China specializing in OB/GYN and is a Licensed Acupuncturist in Florida.
She opened the Atlantic Institute of Oriental Medicine (ATOM) 23 years ago as a non-profit school simply because; “America has given me a lot. I have to give back to the community. I want my own country’s culture and treatment to work for American people”. The college has grown from 10 students to over 150 students. Students must pass four National Board Exams in order to get licensed in Florida.
Joanna Zhao, Academic Dean, has been Director of Five Branches’ TCM Clinic since she co-founded it in 1984. Her commitment to TCM began as a youngster in China, when she became interested in the work of her uncle, a famous TCM doctor. Joanna received her education from the Shanghai University of Traditional Chinese Medicine in the People’s Republic of China, where she trained in both Western medicine and TCM. She studied with noted medical doctors and acupuncturists Xiuyan Lu and Yuan Fang. Joanna has spent more than a quarter of a century teaching and practicing TCM in China and the U.S., working with local oncologists and developing specialties in cancer, immune diseases and mental emotional disorders. Joanna has lectured at the Five Branches’ International Symposium on Women’s TCM and on Pediatric TCM, and has been a guest speaker at the University of California, Santa Cruz. She has also been the lead speaker at national conferences on female reproductive cancer, and leukemia. She has led study tours to China since 1992, where Five Branches’ students and graduates study in Shanghai’s Shuguang Hospital and Zhejiang Chinese Medical University. Joanna is an accomplished musician, integrating Eastern and Western styles of music. Like her teacher and great-grandfather, she is also an excellent calligrapher. Professor Zhao teaches in the Departments of TCM Acupuncture and TCM Herbology, and is a faculty member of the Five Branches DAOM program.
