Chancellor Donald, MD, is the chief medical officer of the Taking Aim at Cancer in Louisiana initiative. He currently holds the position of assistant professor of clinical medicine at Tulane University. His academic focus is advocacy and health disparities regarding patients with hematologic disorders and malignancy. He previously cared for patients in a community practice at Lourdes Oncology Associates in Lafayette, Louisiana.

Originally from Gretna, Florida, Dr. Donald attended Florida A&M University for undergraduate studies and graduated magna cum laude. He then attended the University of Miami School of Medicine for his medical degree. He completed his internship, residency, and fellowship at Tulane University.

In 2010, he joined Louisiana Oncology Associates, PMC, and became president of the practice in 2014. Dr. Donald would subsequently serve as a lead in crafting a professional services agreement with Our Lady of Lourdes Regional Medical Center, where he served as medical director of the oncology service line, a member of the Medical Executive Committee, and a trustee on the Board of Directors. As medical director, he developed an annual lung cancer screening program using low-dose CT scans for 40 patients yearly at no cost to the patient. In 2013, he was given the Spirit of Hope Award by the American Cancer Society.

Dr. Donald has extended himself beyond his practice to advocate for patients and the appropriate delivery of care. Since 2012 he has served as the hematology representative for Louisiana for the Medicare Carrier Advisory Committee (CAC). He functioned as co-chair of the 2017 and 2018 annual CAC meeting in Washington, D.C. Additionally, he served as a designee to the Program Committee for the 2017 American Society of Hematology Annual Meeting.
