Maria Mercedes Chang Villacreses, M.D.

Maria Mercedes Chang Villacreses, M.D., is determined to make a difference in the diagnosis and treatment of diabetes. As a postdoctoral fellow with City of Hope’s Diabetes and Metabolism Research Institute, Dr. Chang Villacreses determined that the popular A1c test may not be sufficient to determine the presence of diabetes. “We want to diagnose diabetes earlier so we can intervene earlier and potentially prevent diabetic complications from developing,” she said. “The best way to do that is by also using oral glucose tests.” Dr. Chang Villacreses is a perpetual honors student who received her medical degree from Ecuador's Universidad Católica de Santiago de Guayaquil. After several years' service as a physician in Guayaquil, she continued her training in the U.S. at Danbury Hospital in Danbury, CT, and Yale New Haven Endocrinology Department, New Haven, CT.
