Our Services

Early Intervention

Early Intervention services, including Speech Therapy, Physical Therapy, and Occupational Therapy, are a very specialized area.

They require knowledge of not only the delays and disorders (e.g. Childhood Apraxia of Speech, Autism, Selective Mutism, Language Delay, etc.) but also the unique paradigm of caregiver education.


Education based English speech therapy services in Japan can be rather difficult to obtain.

Often, international schools do not have the services available for English speaking students due to lack of available English speaking Speech Therapists in Japan.  We can flexibly work with your child's school and teachers.


While Japan has excellent Japanese Speech Therapists, with an emergent medical situation an English speaking Speech Therapist is essential for immediate communication.

Whether for acute or long term care, speech therapy in Japan does not have to be a hardship.  We can provide you with the most advanced speech therapy services.

Accent Modification

Even when grammar and vocabulary have reached the highest levels, non-native English speakers often find they have difficulty being understood due to their accent.

With specialized training in accent modification, we use evidence based methods of modifying your accent for increased intelligibility.
