In 1995 Wearstler opened her design firm, Kelly Wearstler Interior Design. In the late 1990s she decorated the house of real estate developer Brad Korzen who she went on to marry in 2002. Kelly provided design services for residential properties owned by Korzen's Kor Realty Group & went on to redo the interior of the Avalon, a late 1940s-era hotel in Beverly Hills also owned by Korzen. This launched her foray into hotel interior design. Her work within the hotel industry built her reputation as a notable west coast designer. She also designed the restaurant and lounge, BG, at the Manhattan Bergdorf Goodman store.
In addition to her commercial work, Wearstler continuously creates grand residential interiors for some of the most prominent players in the worlds of art, business and entertainment.
