Our vision is to make a positive change to the quality of your child’s life by building skills essential for successful participation in their community, for forming meaningful relationships, and for promoting independence.

Our ABA programs are tailored to meet the unique needs of every individual.
No two programs are the same, because no two learners are the same!


Our programs focus on building on existing skills and strengths, identifying current skill deficits, and teaching new skills to allow the individual to be more independent and able to successfully take part in your family life, educational setting, and in the community.

Progress is continuously monitored and therapy practices are frequently revised to allow changes to the program as necessary to ensure that your child is progressing toward his or her goals. The program may address goals across a range of developmental domains including: communication, social skills, play skills, personal independence and self-care, and motor skills. The program may also focus on reduction of challenging behaviours that are putting your child at risk, are interfering with learning or lowering the quality of your child’s and your life.
