Dr. Llore is an Assistant Professor of Surgery at Columbia University and an Attending Transplant Surgeon at New York Presbyterian Hospital. Dr. Llore received her undergraduate degree from Fordham University and her medical degree from New York University School of Medicine. She completed general surgery residency at Georgetown University Hospital and abdominal transplant/hepatobiliary fellowship training at New York Presbyterian Columbia and Weill Cornell.

She received additional training on the immune response after a liver transplant and xenotransplantation with Dr. Megan Sykes at Columbia Center for Translational Immunology (CCTI).

She is board-certified in general surgery and received specialty training in abdominal transplant and hepatobiliary surgery. Her practice interests focus on the surgical management of children and adults with liver and bile duct disease, including benign and malignant liver tumors. She practices minimally invasive surgical techniques in liver surgery to shorten recovery times and reduce post operative discomfort.

Dr. Llore is interested in surgical education and is the Associate Program Director for the ASTS certified surgical fellowship program.
