Scott has always been extremely passionate about delivering the highest quality of care to his patients – particularly those suffering from concussion and post concussion syndrome. It is that same passion that inspired him to develop The Shift Concussion Management Program – an education and training platform providing Healthcare Practitioners throughout Canada with evidence-informed concussion assessment and rehabilitation strategies for patients suffering from mild traumatic brain injury.

Scott has received diverse training and mentoring over the course of his career. He is certified in vestibular assessment and therapeutic techniques out of Emory University’s prestigious program in Atlanta, GA, and has spent time shadowing in Pittsburgh, PA under internationally renowned Neuropsychologist Dr. Michael “Micky” Collins. Scott is currently a Credentialed ImPACT (Immediate Post Concussion Assessment and Cognitive Testing) Consultant (CIC) and has significant experience with manual treatment techniques such as osteopathic manipulation, craniosacral therapy, and acupuncture.

Scott owns and operates a well-known multi-disciplinary concussion rehabilitation clinic in Guelph, Ontario (Shift Concussion’s head office) which specializes in post-concussion care for sport and non-sport related injuries.

In addition to balancing a busy clinic schedule, Scott lends his time speaking to sports organizations, hospitals, schools, and medical clinics throughout the province on the topic of concussion management.

Kirsten Donaldson

Clinical Services and Education Coordinator,

Read Kirsten's Biography

Ever since she experienced a severe concussion in her first year of her undergraduate degree, Kirsten has taken a great interest in the brain and how it can change and adapt to external factors. This interest inspired her to complete her Arts and Sciences Degree in Neuroscience and Psychology at the University of Guelph in 2020, followed by an Ontario College Graduate Certificate in Brain Disorders Management at Mohawk College in 2021. Some highlights of her education include knowledge translation and transmission, and completing research in the Visual Cognitive Neuroscience Lab at the University of Guelph.

Between her personal experience, education, and work opportunities, Kirsten can empathize with the amount of effort it takes to navigate a brain injury and the many comorbidities that follow. She has worked as a Vision Therapist, helping concussion patients improve vision-related and other concussion symptoms, as well as children who experience vision-related learning challenges. The most rewarding part of working alongside patients is seeing them succeed and become more confident in daily life.
