Dr. Mary Simmering McDonald

Clinical and Counselling Psychologist

I am a Clinical Child Psychologist who provides therapy and assessment services to children, adolescents, and their families. I work with individuals who are experiencing a variety of challenges, such as mood and anxiety disorders, Learning Disorders, AD/HD, Autism Spectrum Disorders, Eating Disorders, behaviour and emotion regulation difficulties, self-harming behaviours, adjustment to life events, and interpersonal difficulties.

I am currently only offering remote sessions (by phone or video). Clients may contact me by email at dr.marysmcdonald@gmail.com to request booking or discuss existing appointments. I will be in touch with clients who have existing appointments directly each week to discuss scheduling. Any cancelation fees are waived during this time. All upcoming assessment testing appointments through April are unfortunately canceled until further notice; however, assessment feedbacks can go ahead as planned.

Theoretical Orientation:

My approach to case conceptualization and intervention is based on a Developmental Psychopathology framework, which considers the biological, psychological, social, and systemic factors that contribute to a client’s presentation. My main theoretical orientation is best described as Integrative in that I use evidence-based strategies and techniques from different theoretical perspectives with a strong focus on Cognitive Behavioural Therapy. I seek to provide a warm, supportive, and collaborative environment and to help individuals, parents, and families feel empowered to build on their strengths to cope with presenting challenges.

Clinical Experiences:

Prior to joining the Centrepointe Professional Services team in 2012, I worked in a variety of settings including children’s mental health centers (e.g., Windsor Regional Children’s Centre, Children First, The Teen Health Centre), university clinics (e.g., University of Windsor Student Counseling Centre), a sexual assault crisis centre, schools (e.g., a preschool for children with autism, local high schools), and pediatric hospitals (e.g., the Windsor Regional Hospital and the Children’s Hospital of Eastern Ontario [CHEO]). I completed my pre-doctoral residency at CHEO with rotations focused on Developmental Disabilities, Eating Disorders, individual and family therapy, neuropsychological assessment, and crisis assessment. My graduate research was funded by provincial and federal scholarships and I have co-authored several publications in the areas of computer-mediated communication (e.g., Facebook), online partner aggression, adaptive and maladaptive coping, and help-seeking behaviours.
