The more work we do on building self-awareness and resilience when all is well,
the better able we are to face life’s challenges when they come our way.

Assessment Services


I believe that knowledge about oneself brings about self-awareness and empowerment. Therefore, conducting a comprehensive psycho-educational assessment and differential diagnoses to children, adolescents, and adults is one way to support individuals who are seeking a better understanding of themself. My approach to assessment is driven by the client’s presenting concerns. I approach each assessment with curiosity and a purpose of providing insight about the client’s personal strengths and potential, while also formulating strategies and recommendations to support their areas of need.


My areas of practice include: specific learning disorder, intellectual developmental disorder, attention, executive functioning, anxiety, and depression.


Professional Background


I am a fully Registered Psychologist with the Saskatchewan College of Psychologists, with Authorized Practice Endorsement (APE) designation. I obtained a Bachelor of Arts degree, with a major in Psychology from the University of Regina. I went on to obtain a Master of Arts degree in Educational Psychology, with a focus on Learning and Development from the University of Victoria, and a Master of Education degree in Educational Psychology from the University of Regina.


I have been afforded many opportunities over the last decade to work in various mental health and community service job roles. I have worked as a Research Coordinator for the Anxiety and Illness Behaviours Laboratory at the University of Regina, a Behaviour Therapist working with persons on the autism spectrum, and a Clinical Caseworker in a residential treatment setting. Over the past several years, I have worked as a Registered Psychologist providing psycho-educational assessment services for schools and community organizations.
