Nathan focuses on a patient centred approach to his treatment programs, considering the patients’ history, goals, barriers and lifestyle, to design and implement an individually tailored treatment plan that will allow for a comfortable and successful progression through the rehabilitation journey. Nathan is results focused, using planning and tracking strategies that lead to the best outcomes for his patients. Taking a biopsychosocial approach is key to Nathan’s services, which includes education and strategies for self-management so that the results last long after his intervention is completed.
