Grand River Autism Therapy

Our Mission

We take pride in knowing the impact that therapy can make; not only for the learner, but the family as a whole. We understand the elements that are at work and we strive to change and enhance each learner’s life through dedication and care.

We are committed to providing exceptional ABA services. We do this by placing the learner in the center of care and tailoring all components of service to make it an exploratory, effective and skill-achieving success. Through pairing, positive reinforcement and skilled professionals, we work with families to make this an inclusive experience where planning and goals are developed to reflect best practice and to align with parental visions for their child.

    Founder & Owner — BCBA, M.Ed, RBA (Ont)

    I am proud to say that I am the founder and owner at Grand River Autism Services Inc. and have been working in this field for over 9 years now. I started GRAS inc. in 2019, and I am fortunate to say I have such an amazing, passionate team alongside me. I know that collaboration and team unity is pivotal to our success each day! I work as a Board Certified Behavior Analyst (BCBA) providing services to an array of individuals with a designation in Autism Spectrum Disorder. I have a Master in Education and Behaviour Analysis, an Honours degree in Sociology and a vast background in Psychology. I am an ongoing member of ONTABA and an active member of the College of Psychologists and Behaviour Analysts in Ontario. I continue to find enjoyment in the active learning that this field presents and finding creative pathways to blend and build new skills. I am a strong believer in working with families to achieve the goals that are best suited for their child. I strive to have a reciprocal relationship between myself, my team, and the clients we are providing services for; together we can build progress and independence. If my journey has taught me anything, it is that growth is infinite, and action is the driving force of change!
