Nathalie Sagar, MA, Ph.D.(c)


Ms. Sagar is a senior clinical associate with six years of experience providing assessment and treatment services to children and youth. When conducting assessments, her goal is to develop an in-depth and comprehensive understanding of the child. This helps parents and teachers tailor supports to build on the child’s strengths and implement targeted strategies for areas of need. Throughout the assessment, fostering comfort and connection is her priority. She is committed to collaborating with children and parents to make the assessment process as easy and engaging as possible. 

Ms. Sagar is currently in the final stages of completing a doctorate in School and Applied Child Psychology at the University of British Columbia. In 2022-2023, she completed a pre-doctoral internship at the Sick Kids Centre for Community Mental Health. Prior to this, she worked as a certified school psychologist, consultant, and doctoral practicum student in a variety of clinical settings in British Columbia including hospitals, private practices, schools, and community-based clinics. In these settings, she conducted a wide variety of complex psychological assessments for children and youth with varying needs and abilities, including psychoeducational and social-emotional assessments. All of Ms. Sagar’s work is done in collaboration with and under the supervision of Dr. Julie Wallis.
