Welcome to SEIBIKAI ORTHODONTIC CLINIC

Seibikai Orthodontic Center（SOC） was founded by Dr. Keishi Matsumoto in 1967 in Shinjuku that is the central district of Tokyo, capital of Japan. Dr. Keishi Matsumoto mostly had the orthodontic training from his father Dr. Shigeaki Matsumoto who was the student of Dr. E. H. Angle who is called “Father of orthodontics”. Dr. Shigeaki Matsumoto started the Edgewise treatment in Japan in 1927 and he was one of the pioneer of the orthodontics in Japan.

Dr.Kazunobu Yoneyama joined to SOC in 1975. He got the orthodontic training at SOC and Dr. Hito Suyehiro who used to have several offices in Washington DC and Maryland. Now Dr.Yoneyama is the clinic chief of SOC. He was also vice president of Japanese Association of Orthodontists （JAO）. Both of them are the international member of American Association of Orthodontists. Two other orthodontists are working at SOC. There is no doubt that SOC is one of the most sophisticated orthodontic office in Japan. In 2007, the SOC moved to the new office, and office’s name was changed to “Seibikai Orthodontic Clinic”.
