Mary Humble founded her pool service business in 1976 with the idea of treating every pool as if it were her own. She launched her dream with nothing more than a beat-up '62 green pickup truck and a tremendous work ethic. The company grew steadily with an all-woman workforce for over 20 years. I remember in 1998, her son Stoni and I were in business school together and in need of summer employment. We went to work for Mary and were eager to "help" her with all we had been learning from our professors at Wichita State.
