Katharine “Katie” Sise is a New York City based author, jewelry designer and television host. Years ago, at age twenty-four— after dropping a rare and very expensive bottle of champagne on her way to deliver it to Robert De Niro’s table—she realized she needed a way to fund her acting and writing career that didn’t involve balancing a tray full of cocktails. That fall, she taught herself to make jewelry and launched Katharine Sise Jewelry. Within a few months, Lucky Magazine called her a “Designer to Watch” and her company appeared in every major fashion magazine—including Vogue, W, Elle, Self, Lucky, InStyle, Bazaar, Allure, Us Weekly, People, In Touch, Page Six Magazine, Real Simple, FN, Life and Style, Teen Vogue, Seventeen, Women’s Wear Daily, Marie Claire and Glamour. Before she knew it, her celebrity clientele included Kate Winslet, Cameron Diaz, Kelly Ripa, Ellen Pompeo, Mary-Kate and Ashley Olsen, Beyonce Knowles, Anne Hathaway and Drew Barrymore.

Katharine has been profiled on dozens of online fashion and lifestyle outlets including Forbes.com, Elle.com, InStyle.com, People.com, Sweet, The Huffington Post and The New York Post. Her jewelry has appeared on television shows such as The View, Live with Regis and Kelly, E! News, Good Day New York, Full Frontal Fashion, Movie and a Makeover, The O.C., Brothers and Sisters and Gossip Girl. While Katharine was chatting with the ladies from The View, one of her necklaces broke on air and fell from her neck to her lap because she didn’t spend enough time getting the clasp right. That moment is preserved, forever, on a DVD at her parents’ house.

Katharine has designed jewelry for national campaigns like Vera Wang, Gap and Keds. In 2009, Target launched Katharine Sise for Target.

Katharine has worked as a fashion and lifestyle consultant, appearing on-air for networks like HSN, Oxygen, Discovery Channel, CNBC and ABC’s Good Morning America. For eighteen months, Katharine co-hosted a live monthly television show for The Home Shopping Network. She also appeared as The Daily Special’s resident style expert.

Katharine’s first book, Creative Girl: The Ultimate Guide for Turning Talent and Creativity into a Real Career (Perseus/Running Press) hit shelves in September of 2010. Creative Girl is written for every woman who wants to make her living in the creative world, whether in an office job or at the helm of her own business. The book is an encouraging and practical take on how to make a living doing what you love.

Katharine’s first novel, The Boyfriend App, was published by HarperCollins Balzer + Bray on April 30, 2013. The Boyfriend App tells the story of a girl who, in order to win a scholarship offered by a secretly-evil global computing corporation, invents an app that makes any boy fall madly in love with her, with chaotic results. The Boyfriend App has received rave reviews from Publisher’s Weekly, Booklist, School Library Journal, and VOYA.

Katharine has a BA in Film, Television and Theater from The University of Notre Dame. She lives in New York City with her family.
