Marvellous Mouth Children's Speech and Oral Language Therapy



A good story has a beginning, a middle and an end.

Our story began in California almost 30 years ago. Chapters were written in Wisconsin and Florida. The bulk of the adventures have been in Ireland with short diversions to the UK and China. We now come to a happy ending as Barbara retires and Seamus moves on to an entirely different venture.

We send our best wishes to the educators and speech and language specialists who continue to use Mouthercise and Builders Club to engage children in effective and enjoyable communication.

If you wish to contact us, you can do so by email to

Sincerely yours,

Barbara and Seamus Hallahan
