Today… I commit my life and energies to practice the profession of Medicine. I will use the science of medicine, my acquired skills, and innate aptitudes to diagnose and treat all persons who want or need my care.

Caring for patients will be my primary mission and one that never will be influenced by promise or acquisition of personal reward. I will continue professional learning each day. I will monitor myself and my colleagues to assure the strength of our integrity and ethics.

I will avoid giving excessive, futile, or insufficient care for any person. I will work with others to promote health within broad populations. I will strive to maintain physical and emotional health in myself and my family.
