She taught at George Brown College for 5 years, and is qualified to supervise individuals pursuing their BCBA and BCaBA certification and to provide regular supervision to RBTs and BCaBAs.

Leigh is dedicated to providing an individualized learning plan for each client that is put together using evidence-based strategies and goals set by both the treatment team and the client’s family. Leigh is the mother of an amazing 2-year-old son, and learned the importance of advocating for him early on. She currently resides in Whitby with her husband, son, and two dogs.

ABA Therapist

Tracy Sturley

Behaviour Therapist

Tracy Sturley graduated from McMaster University with a B.A. in Psychology and soon after kick-started her career in the printing industry, which influenced a solid business acumen and highly transferable skillset. While Tracy's academic background was not directly aligned with her career path, she was able to leverage the knowledge acquired from her B.A. to advocate for her own children later in life. Having two teenage boys who were diagnosed with Autism at an early age, Tracy learned quickly that she would be the primary advocate and support for her boys. She made the the difficult decision to leave her corporate career when her youngest son was two in order to start a private home daycare. This provided Tracy with the flexibility to focus on advocating for her boys and ensuring they were receiving the support they needed.

At her private home daycare, Tracy created a structured learning environment one would get from a childcare centre, but with the love, care, and attention kids would receive at home. She cared for children from 9 months to 12 years of age, at various developmental stages and some with varying special special needs. After running this successful business for 10+ years, Tracy decided to pursue her passion for working with children with special needs as an ABA Therapist. She is currently working towards her RBT certification and is truly excited to be an integral member of the Together for Better Therapy team.
