Altrusa International, Inc. is a service organization of business and professional leaders - classified by occupation - dedicated to improving their communities through service to others. The word `Altrusa` is a derivation of the word altruism, defined as the principle or practice of unselfish concern for or devotion to the welfare of others. Altrusa was coined by taking the first four letters of the word Altruism and joining them with U.S.A. from the United States of America.
