BECAUSE I honor the inborn potential of everyone to be truly healthy.
BECAUSE I desire to help the newborn, the aged, and those without hope.
BECAUSE I choose to care for the patient with the disease, not the disease.
BECAUSE I wish to assist rather that to intrude; to free rather than control.
BECAUSE I seek to correct the cause, not its effect.
BECAUSE I know doctors do not heal, only the body can heal itself.
BECAUSE I have been called to serve others.
BECAUSE I want to make a difference.
BECAUSE every day I get to witness miracles.
