Jessica Catto Dialogue | Michael Curtin

Michael Curtin, CEO of DC Central Kitchen (DCCK), will present a free Jessica Catto Dialogue lecture on August 9th at Paepcke Auditorium in Aspen. The lecture, entitled “8 Rules for Righteous Entrepreneurs,” will explore specific decisions from DCCK’s most challenging situations to illustrate the rules of righteous entrepreneurship and how those rules have created tangible new best practices for social enterprises. 

DC Central Kitchen is America's leader in rebuilding urban food systems through social enterprise programs such as training unemployed adults for culinary careers and reducing hunger with recycled food. When Mike joined DCCK in 2004, he drew on his experiences as an entrepreneur in the restaurant business to fund and launch DCCK’s Nutrition Lab Facility and expand the Kitchen’s social enterprise portfolio from a small catering outfit to include a full-service catering, contract meals, locally-sourced, scratched-cooked school meals, and a wholesale program that delivers fresh produce and healthy snacks to corner stores in Washington DC’s food deserts. These efforts engage local farmers, graduates from the DCCK culinary job training program, area school children, tens thousands of volunteers, local merchants, federal and local governments, private foundations, corporations, and individual investors to create more access to healthy food and feed rural and urban economies while reducing recidivism and community carbon foot prints. DCCK employs over 150 people, including 60 graduates of the Kitchen’s nationally recognized Culinary Job Training Program, which trains formerly incarcerated, addicted, homeless or chronically unemployed individuals. 

As a result of this work centered around food, economic, and environmental justice, DCCK has been featured in the District of Columbia’s “Sustainable DC” Plan. Additionally, DCCK has been honored with the Washington Business Journal’s “Green Business Award for Innovation” (2010), the “DC Mayor’s Environmental Excellence Award,” The DC Chamber of Commerce’s Community Impact Award” (2012), and the 2015 “Grand Prize Golden Carrot Award” from the Physicians Committee for Responsible Medicine, which “recognizes food service professionals doing an exceptional job of improving the healthfulness of school lunches.” 

Mike lives with his wife, Maureen, and their three children, Maeve, Michael III and Ciara, in Falls Church, VA.

Please walk, bike, bus, or carpool to Paepcke Auditorium as parking is very limited. RSVP does not reserve a seat.

ACES’ Jessica Catto Dialogues honor the environmental legacy of Jessica Hobby Catto through a speaker series featuring visionary thinkers and doers from all realms of environmental concerns. The series is supported by the Catto and Shaw families in Jessica’s memory.

Around the Ranch
Winter is one of my favorite times of the year as a farmer. The cold weather and short days almost force us into a time of reflection, planning and research. This year is no different and the Rock Bottom Ranch agricultural team has spent the better part of December reading books, finalizing 2017 growing plans, and designing new infrastructure to make our work in 2017 even more productive and efficient.
