Overmiller began her professional career as a bartender and waitress at Proximo Restaurant Group's Austin Grill in Washington, DC. Realizing she craved more experience in the kitchen, she then made the shift to Cafe Atlantico, also part of Proximo, where she worked as a line cook while attending the esteemed L'Academie de Cuisine in Maryland. In 2002, she graduated and accepted a position at Ristorante Tosca under the direction of Chef/Owner Cesare Lafranconi. At Tosca, she quickly moved her way up from Line Cook to Pastry Chef to Sous Chef. With a desire to broaden her experience after spending three years at Tosca, Lanfranconi made a phone call to Chef/Owner Cathal Armstrong on Overmiller's behalf, which brought her to Restaurant Eve in Old Town Alexandria, Virginia. Chef Armstrong�s leadership taught Overmiller about the importance of local vendors and sourcing from local farms, along with honing in on her technical culinary skills. Armstrong added French techniques to Overmiller's Italian preparation, and soon she found a balance between both of her mentors� skills. As a 2004 Jean-Louis Palladin Foundation award recipient, Overmiller had the opportunity of a lifetime to travel to Italy and learn about ingredients and cooking techniques. She has proven herself in many kitchens and now, as the Executive Chef at the latest addition to the Armstrong's projects, which opened in May 2007, Overmiller continues to use the skills she has developed throughout the years.
