Sudden entrepreneur

Dr. Ruth Rojas's resume is littered with quirks.

Born in Colombia, she learned English in Toronto when she was an exchange student in 20s. She pursued a career in graphic arts and worked in web development for furniture company Ethan Allan in Philadelphia.

A little more than a decade ago, Rojas decided to chase another dream. She went to dental school, at Temple University in Philadelphia, and followed that with a three-year residency in a prosthodontistry, a specialty in replacing and restoring patients' teeth. Later, she was a hired as a prosthodontist at a U.S. Air Force base in New Jersey.
