Katherine began her career as a fashion model, discovered by photographer Patrick Demarchelier after earning her degree from Villanova University's School of Business. As a model, she has been featured in fashion runway shows, magazine editorial spreads, television work, and advertising campaigns, in domestic and international fashion markets.

Katherine took a hiatus from the fashion world for which she was featured on CNN World News. She left her fashion career to pursue her U.S. government teaching certification simultaneously with work as a schoolteacher of immigrant children in an inner city for over five years. An artist since childhood, she developed a series of decorative arts and jewelry during this time which was inspired by the diverse cultures of her students and international travels as a model, which was featured in a show at an art gallery as the first public show of her creative works.

She lives in New York City with her husband. She continues her jewelry designs which express her interest in global culture, having worked with artisans in locations including Kabul, Afghanistan, Cape Town, South Africa, and New York City. She recently styled the cover of L’Officiel magazine, featuring solely sustainable fashion designs, an expression of her passion for style and sustainability, and is an avid collector of vintage fashion.

Katherine has been an invited guest speaker, panel moderator, and interviewee at educational and media venues, and continues to use her voice to advocate for education and global citizenship.
