Dieterle's professional career began at
Della Femina in the Hamptons for two years. That was followed by three years at
Red Bar and two years at
1770 House, both in
New York City. For almost five years, he was a
sous-chef at
The Harrison restaurant in New York. In October 2005, Dieterle competed in and won the first season of
Top Chef. Following his win on the series, he left
The Harrison in early 2006 to plan the opening of his restaurant. His first restaurant, Perilla, opened in May 2007 in New York City. In 2010 he opened Kin Shop, a Thai restaurant. In a positive 2010 review of Kin Shop in the magazine
New York, food critic Adam Platt called Dieterle "the original (and easily most talented) winner" of
Top Chef. In 2012, he opened The Marrow in New York City, which featured a mashup of Italian and German cuisine that was an ode to Dieterle's German heritage, and his wife's Italian heritage. The Marrow closed in 2014 after less than two years. In late 2015, Dieterle closed his two remaining restaurants, Kin Shop and Perilla. Dieterle said he was taking a leave from the restaurant and hospitality business. In 2019 he helped open a new restaurant in Williamsburg. Dieterle worked as a consulting chef at the restaurant named Ten Hope and put together the menu. Perilla alum Jim Handwerker works as chef de cuisine. In 2016 Dieterle served as a consultant for the AMC TV series
Feed the Beast, set at a fictional restaurant. == Personal life ==
