Sarra has been a registered psychologist since June 2020 in Alberta. Her core values as a psychologist include maintaining integrity in relationships, honouring diversity, and delivering her work with optimism and professionalism.

Experience in private practice since 2021

Approved provider capacity assessments
Strives to provide high quality and ethical service
Highly regarded in the community


Sarra has worked alongside Sharon since 2021 and has taken the lead to become the Clinical Director at Sharon Blott Psychological Services in 2023, which began in 2010 with Sharon providing psychological assessment services for children, adolescents, and young adults. In March 2024, Sarra has taken the next step to change the name to Constellation Psychology. The new name refers to the concept of a mental constellation, a collection of interconnected elements (i.e., thoughts, emotions, memories, and experiences) that shape an individual's mental landscape and personality, much like the stars forming constellations in the night sky. It also expresses an approach to help clients understand the complex interplay of their current challenges and to empower themselves to bridge the gap, reach their potential, and succeed.

Sarra has a Master of Education degree in School and Applied Child Psychology from the University of Calgary. Her training was completed at both the Calgary Board of Education and the University of Calgary, allowing her to specialize in psychoeducational assessments for children, adolescents, and young adults. Sarra also has 5 years of experience directly supporting individuals with autism spectrum disorder, ADHD, and developmental delays within multiple settings (i.e., home,  school, and community) and programs (i.e., PUF and FSCD).

Sharon has been a registered psychologist since March 2001. As a provisional psychologist (1998-2001), she worked for the Calgary Catholic School District and, once registered, obtained a position with the Calgary Board of Education, which she maintained for five years. She subsequently assumed the role of Manager of Assessment Services at Foothills Academy, a private school dedicated to the educational needs of students with learning disabilities. She resigned in 2010 so that her own children could attend school. She chose to establish a private practice in October 2010 to meet her clients' needs better. Long waiting lists for assessments, limited resources, and system politics left many families feeling frustrated and alone in their search for support for their children. As a parent with two grown daughters with special needs, including learning disabilities and ADHD, Sharon understands the difficulties families experience as they attempt to navigate the system. She brings both a personal and professional perspective to her work.

Since registration, she has consistently strived to provide a high-quality, ethical service. She adheres to the many guidelines and standards of practice set out by the College of Alberta Psychologists. She maintains continued competency in her practice by attending workshops and webinars, listening to podcasts, and reading current research. Her foremost guiding principle is respect for the dignity of persons. This is evident in all her interactions with clients, and she values their trust as she works with them and/or their children.

Her work is highly regarded in the community, and feedback about her comprehensive reports is consistently positive. She values diversity and works with families from many different cultural backgrounds.
