Dr. Marie Hooper, C.Psych. (Supervised Practice) (She/Her)

Director & Founder

Dr. Marie Hooper is a psychologist in supervised practice, educator, researcher, clinic founder, and mother of two. She is the Founder of Flourish Health Services, a neurodiversity-affirming interdisciplinary clinic in Toronto providing assessment, therapy, consultation, and group programming across the lifespan, from toddlers to seniors.

Marie completed her Ph.D., M.A., and B.A. in Psychology at York University, where she now teaches undergraduate psychology courses. Teaching is one of her greatest professional passions. She is committed to helping students connect research, clinical practice, development, mental health, disability, family systems, and lived experience in thoughtful and meaningful ways.

Marie provides psychological services in supervised practice, including assessment, individual therapy, couples therapy, family consultation, and diagnostic clarification. Her work includes autism, ADHD, learning differences, developmental differences, anxiety, mood concerns, OCD-related presentations, giftedness, PDA profiles, high-masking neurodivergence, relationship concerns, and complex clinical questions.

As a late-diagnosed autistic and ADHD clinician, Marie thoughtfully integrates lived experience with clinical training. Her work is strengths-based, evidence-based, relational, trauma-informed, neurodiversity-affirming, and gender-affirming. She is committed to creating spaces where individuals and families feel respected, understood, and supported.

At Flourish, Marie contributes to interdisciplinary care, program development, teaching, community collaboration, and clinical training. Flourish brings together psychologists, speech-language pathologists, occupational therapists, psychotherapists, social workers, and other professionals to support children, teens, adults, couples, and families.

Marie developed Flourish’s Whole Child Assessment and Integrated Developmental Assessment approaches. These approaches look beyond isolated symptoms or scores and consider development, cognition, learning, executive functioning, adaptive functioning, sensory processing, mental health, identity, relationships, family context, and environmental fit.

Flourish also maintains many partnerships with schools, physicians, psychiatrists, hospitals, community agencies, children’s mental health organizations, and developmental service providers. Through these collaborations, Marie works to support coordinated, integrated care and help families navigate complex systems with greater clarity and support.

Marie serves on the Board of Directors for PDA North America, where she contributes to education, advocacy, and research related to Pathological Demand Avoidance. She is committed to trauma-informed, low-demand, autonomy-based approaches that support children, teens, adults, families, schools, and clinicians.

Marie co-created Club AuSome, an affirming social-emotional group for autistic girls and gender-diverse youth, and Autism Reframe, an educational initiative focused on reshaping how autism is understood, assessed, and supported. She is also leading the development of a school for autistic girls inspired by Limpsfield Grange School in the United Kingdom.

Her doctoral research examined the psychosocial experiences of siblings of children with disabilities and involved adapting the SibWorkS intervention into a virtual format called iSibWorkS. This work demonstrated improvements in resilience, emotional well-being, and social connectedness, and continues to shape Marie’s relational, family-centred approach to care.

Across her clinical work, teaching, research, advocacy, and leadership, Marie is committed to creating systems where neurodivergent people and their families are not only supported, but understood, respected, and able to flourish.
