    Dorrie KoscielnukRegistered Psychologist

    Like a fingerprint, every child is unique in the way they think, learn and behave. I have worked with children and adolescents for many years, and was always intrigued by those who ‘marched to their own beat.’ I want to march to their beat too. I want to hear them. Understand them. Understanding is what pushes me as a psychologist. Read more

    My path in life wasn’t always clear to me. During my childhood, I tended to fleet from one fanciful career idea to the next. Perhaps I would be a world-renowned journalist or maybe a five-star chef. At one point I was convinced I would live on a compound and make organic soaps. While none of those plans came to fruition, sitting in my first undergraduate psychology class, something “clicked”. I was hooked and spent the next several years pursuing all things psychology.

    I was born in Germany and moved to Canada after high school to attend university. In 2016, I graduated the Ph.D. program in Clinical Neuropsychology in Windsor, Ontario and have been practicing in Edmonton ever since. I love that my job provides me with many opportunities to have a positive impact on a child’s life and to help them get set up for success in their academic journey. Read more

    Being a psychologist allows me to help parents and educators to better understand the unique strengths and challenges of their child or student. This understanding helps to facilitate a supportive home and school learning environment, where specific needs can be addressed and strengths can be embraced. It brings me great joy to help children and adolescents to feel more understood and supported. Read more

  • Jana Roberto


    I have always had a passion of working with and supporting children and their families. I have extensive experience in both the assessment and treatment of infant, preschool, and school-aged children. One of my areas of specialization is working with children with Autism Spectrum Disorder (ASD) and in supporting families through their journey. Most of my private practice is focused on the diagnosis of ASD, however I really enjoy having a mix of both assessment and treatment in my private practice role. Read more

  • Paula Oliveira-Lauterbach

    Paula Oliveira-LauterbachBehavioural Consultant & Psychometrist

    From a young age, I knew that I would devote my work life to children, adolescents and families. Being in the company of young people is entertaining, inspiring and informative. This led me to university where I had the opportunity to study childhood development, human behaviour and education. Over the past 25 years I have worked alongside children, adolescents and families in the childcare, school, public and private sectors. I am also a mom to two wonderful boys. In all my experiences, I have learned how to manage, accommodate and encourage behaviours in young people to lead healthy and functioning lives in their environments. It takes a village to raise a child and I look forward to being that person in yours! Read more
