Our philosophy is that of George Washington Carver, an African American scientist who taught sustainable agriculture to poor farmers. Through experimentation of plants, he developed hundreds of uses for peanuts and other plants. Although most-well known for these inventions, Carver served his community through improving racial relations, tutoring children, and serving poor people.
