My clinical practice is guided by the principle to always do what is best for my patients and to be a patient advocate. My administrative goal has been to always be FAIR to everyone and promote the interests of all but protect those who need it. My research has been guided by a desire to discover things that may make a difference in clinical practice. If there is any overall motto, it might be “The law does not obligate you to do what is wrong. If you believe so, you are mistaken.”
