After completing his Acupuncture Studies in 1989, David specialized in palpation-based acupuncture influenced by Japanese styles, mainly Master Nagano and Kiiko Matsumoto, as well as Master Kawai. Blending the Japanese styles of acupuncture with European microsystems and Low-Level Laser therapies became a gentle yet very powerful treatment modality. During his 30 years in clinical practice, he continued developing and integrating concepts learned from Prof. Nadia Volf (auricular causative diagnosis), Dr. Yamamoto (scalp acupuncture), and Prof. Jochen Gleditsch (very point and Microsystems) into the verifiable Palpation-Based style he has adopted. For 16 years, until 2020, David was the co-director and teacher for the Structural acupuncture course for physicians at the Harvard Medical School, Cont. Ed. He also taught at the New England School of Acupuncture and currently is teaching for DÄGfA in Munich, ABZ Mitte in Frankfurt as well as Paris and Zürich Recently, David has created a website (www.ohmatopoeia.com) that is developing an art and acupuncture platform, offering CEU/CME credits as well as offering a peek into some art.
