Dr. Umpierrez heads the Emory Latino Diabetes Education Program (ELDEP), the first nationally accredited all Spanish Diabetes education program dedicated to providing diabetes education and lifestyle intervention to Latinos in Georgia

Under his leadership, the ELDEP has received funding in the amount close to $500,000 from the Healthcare Georgia Foundation and the pharmaceutical industry to develop a culturally sensitive, community-based diabetes education program targeting Latinos in metro Atlanta and throughout the state of Georgia. Umpierrez spearheaded the development of a video produced by the ELDEP "Viva mas y major…con su diabetes bajo control!" live longer and better with your diabetes under control!

Personal Statement:
I am committed to the mission of Grady and feel both honored and humbled by the opportunity to help the indigent and inner city population. I am motivated every day to continue to serve and to develop mechanisms to assure quality diabetes care in this vulnerable patient population at high risk for diabetes complications.
