She soon switched from the theatrical to a leadership scholarship, studying telecommunications and child psychology while taking an interest in family law.  This was the vehicle that led to her winning the Miss California and Miss USA pageants, being crowned the forty-first Miss USA. As Miss USA, Marketic spoke an average of twelve times a week, making her one of the most requested speakers in its history. She spoke out on issues concerning children, the decline of the American family, and shared her experience growing up with an alcoholic father who has since restored his life both physically and spiritually.

Writing is one of Marketic's passions. She gained acceptance into the Whos Who in American Women for her writing accomplishments. While still a teenager, Prime Time Magazine, named Marketic columnist and editor, allowing her to traveled through the middle east and Europe writing for various teen publications. Published in many periodicals, she is also the author of two yet to be released books. Her first book, Raising Parents, is an exposition of childrens perspectives on how parents can be more effective during a childs difficult years. Her second book, tentatively entitled Real Beauty, Real Women, teaches women to maximize feminine potential by turning their eyes inward, rather than focusing solely on outward beauty. On the same subject, Marketic conducts image workshops called GirlPower! across the country for women who want to maximize their potential for success both professionally and personally.
