“As Physicians, our daily commitment to doing what is best for our patients is inspiring, and honorable, but it can also be challenging. Often our profession causes us to enter the lives of our patients in moments of stress and vulnerability. The relationship between doctor and patient must be created through compassion, trust, and respect. Part of how we earn and maintain this trust is through a commitment to uphold the highest standards, we as physicians collectively embrace throughout our training in medical school, residency and fellowships over a decade of hard work and sacrifice, this is achieved through complete dedication, compassion, and respect for our patients and medicine. I salute every physician who puts their patient’s wellbeing first and follows their Hippocratic oath to the fullest.”
