Keiko Yoshinaka – Hiroshima, Western Japan

Keiko Yoshinaka is a Registered Dental Hygienist and Orofacial Myofunctional Therapist. She was trained in the Buteyko Method by Patrick McKeown in association with AOMT in Los Angeles.

Keiko has worked at oral surgery, pediatric dentistry, periodontics and orthodontics for over 15 years. She has witnessed people who have not only tooth decay and gum disease but also incorrect breathing and swallowing habits.

Keiko herself had orthodontic treatment twice in her life because of mouth breathing habit and incorrect tongue position. No dentist or orthodontist taught her Orofacial Myofunctional Therapy. She personally found AOMT and the Buteyko Method on the internet, and was impressed with these therapies that support the development of straight teeth, a beautiful face and a productive life.

Keiko finds the Buteyko Method absolutely essential to teaching Orofacial Myofunctional Therapy. She is passionate about spreading the word about healthy breathing and swallowing habits to make people’s lives better.

Keiko provides Orofacial Myofunctional Therapy and teaches the Buteyko Method to ensure correct beathing, tongue posture and swallowing pattern to individuals and groups in both live and online settings for children and adults. Teaching is available in Japanese and English.
