Dr. Almandoz is originally from Trinidad and attended medical school in Dublin at the Royal College of Surgeons in Ireland. After graduating first in his medical school class, he completed a residency in Internal Medicine at the Mater Misericordiae Hospital in Dublin. This was followed by additional training in Internal Medicine and a fellowship in Endocrinology, Diabetes, Metabolism and Nutrition at the Mayo Clinic in Rochester, Minnesota. He was attracted to UTSW by the opportunity for further training and research in Nutrition and Metabolism in the Center for Human Nutrition. Dr. Almandoz brings to UTSW a complementary background of integrated patient-centered care and clinical research. His clinical practice focuses on obesity, weight loss, diabetes, cholesterol and fat metabolism. Dr. Almandoz is board certified in Internal Medicine, Endocrinology and Obesity Medicine. Current research projects look into the impact of metabolic health in normal weight and obesity on the risk for cardiovascular disease, and the genetics of early onset diabetes. Dr. Almandoz’s interests outside of medicine include family, food, exercise and travel.
