My philosophy of care is based on the core values of innovation, respect, collaboration and empowerment. I believe that in order to achieve positive clinical outcomes, we must continuously innovate our delivery of care. The application of up-to-date research and evidence-based guidelines are essential to the care of my patients. It is a privilege to be involved in a patient’s health care and I aim to build a trusting relationship with each of my patients. I respect and value patients’ preferences, cultures and viewpoints when approaching their healthcare goals. The care I provide is based on a collaboration with the patient and members of the healthcare team. I enjoy partnering with patients and families to achieve a personalized, holistic approach to their needs. As a provider, I strongly believe that by empowering patients with knowledge, resources, and support, they are able to drive their care and meet their goals.
