TENNILLE Farley's four-year-old son Tyrhys used to be uncontrollable and he "could barely string two words together".
But after years of therapy at St Giles at Newstead, her son, who has autism spectrum disorder, can communicate and is much better at handling social situations.
"It (St Giles) has been a fantastic help, he has come so far," she said.
"He can explain himself to the other kids about how he likes to play but before they could not understand him.
"Before he was frustrated because he could not communicate."
The therapy has helped her overcome one of her greatest fears - that her son would not go to school.
He attends Glen Dhu Primary School once a week for pre-kinder learning and looks set to continue next year.
And now Ms Farley is set to give back to St Giles by joining Walk With Me in Launceston on Saturday.
She is a St Giles ambassador, meaning she and her family will be at the front of the expected 1000 walkers who will, on Saturday, walk through Launceston as part of a national day of disability awareness.
