    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.

    I have been a psychologist for over 15 years. I use practical, real-life, evidence-based strategies to help children and adults understand challenges and address them effectively. I have been blessed with the chance to help people grow and change, to break old habits, and to understand ways to help their children. I love my job!

    From a very young age I would tell my mom that I wanted to be a psychologist when I grew up. I always liked the idea of helping people feel better, and this career helps me do that every day.

    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.

  • Kendal Toll


    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.

  • 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.

  • Francess Tassone


    We all have moments where we feel stuck with a problem or hit a rough patch. In my practice, I work with adults, kids, teens and parents, utilizing either therapy or assessment, to help them during these times. No matter who I’ve worked with, I have seen that we all have the same desire to be understood and supported. My goal is to give each of my clients that experience.
