Jason Duthie
Administration
Hi, I’m Jason, the admin here at Shaping Growth ABA! In my role, I get to do a little bit of everything; one day it’s billing, the next it’s making sure the toys are clean and ready for action. With a background in customer care, operations and project management, I'm here to help keep things running smoothly so our families and behaviour analysts can focus on what really matters.
Whether it’s answering questions, fixing problems, or just making sure things don’t fall apart—I’m here to help!

Grace Nolan
Registered Behaviour Analyst
I'm Grace Nolan, a Board Certified Behaviour Analyst (BCBA) and Registered Behaviour Analyst (RBA) in Ontario with 10 years of experience in Applied Behaviour Analysis (ABA). I've had the privilege of supporting autistic children, adolescents, and young adults in diverse settings, including in-home, clinic-based programs, and community environments.
​
My practice is rooted in an ecological approach—I believe in considering all aspects of an individual’s life to ensure supports are holistic, socially meaningful, and sustainable. As a mother of two young boys, I bring deep empathy and a firsthand understanding of family dynamics to my work. I am passionate about making ABA services accessible and easy to understand, with the ultimate goal of empowering families with practical tools that foster growth, independence, and an improved quality of life.

Karen Palmer
Registered Behaviour Analyst
Hi, I am Karen Palmer, a Registered Behaviour Analyst with over 20 years of experience supporting autistic children and youth across home, school, agency, and residential settings. I am deeply passionate about helping learners develop meaningful skills in communication, self-help,
play, and independence through individualized, strength-based programming.
I enjoy working in close partnership with parents and caregivers, recognizing the child–family relationship as central to growth and long-term success. My approach honours each learner’s unique communication style and focuses on building trust, cooperation, and autonomy using evidence-based practices such as Functional Communication Training (FCT), augmentative and alternative communication (AAC), and Skill-Based Treatment.
My goal is to create meaningful, lasting improvements in the daily lives and overall quality of life of the individuals and families I serve. Outside of my professional work, I enjoy spending time in nature, time with my two sons and our cats.
​​
I look forward to working with your family!

Arwen Hunter
Registered Behaviour Analyst
I'm Arwen, a Registered Behaviour Analyst and BCBA who supports school-age children and their families. As a mom of three, I understand the realities of navigating school systems and advocating for kids with different needs. ABA is my second career after working with an international toy company—an experience that shaped my love of play, creativity, and making learning genuinely engaging. I bring that blend of fun and evidence-based practice into every session and am passionate about creating supportive, inclusive environments where children feel excited to learn.
I live in West Toronto with my husband, three kids, and our dog, Mookie (who may or may not be the favourite). When i'm not working, you can usually find me reading, relaxing by the water, or competing for my children’s attention.

Hi, I’m Mojgan Zarrabi, a Board Certified Behaviour Analyst (BCBA) and Registered Behaviour Analyst (RBA) in Ontario. I hold a Master’s degree in Developmental Psychology and Education from the Ontario Institute for Studies in Education (OISE) at the University of Toronto.

Kari Wilcox
Registered Behaviour Analyst
I’m Kari, a Registered Behaviour Analyst and a BCBA with over nine years of experience in the field. My passion for behaviour analysis began in my teen years when I volunteered with a drama and dance program for children and youth with exceptional needs. This formative experience first introduced me to the power of meaningful connection, growth and inclusion.
Since then, I have dedicated my career to supporting children and families, with a special focus on early intervention. I love to see children develop new skills and build confidence, celebrating the wins along the way no matter how small!
My goal is to help others to experience the energy and joy that comes learning. I believe learning should be enjoyable for everyone involved– clients, parents, students and colleagues alike.
