Oksana Hamidi, D.O., is a faculty member in the Division of Endocrinology and Metabolism at UT Southwestern Medical Center. She specializes in pituitary, adrenal, and gonadal disorders.

After earning her medical degree at the Chicago College of Osteopathic Medicine, she completed a residency in internal medicine at Rush University Medical Center and John H. Stroger, Jr. Hospital of Cook County. She then received advanced training in endocrinology through a fellowship at the Mayo Clinic in Rochester, Minnesota.

Dr. Hamidi is board certified in internal medicine. She is an active member of several professional organizations, including the Endocrine Society, the American Association of Clinical Endocrinology, and the Pituitary Society.

Her clinical practice and research focus on a multidisciplinary approach to patients with pituitary disorders such as pituitary tumors, hypophysitis, and hypopituitarism. Dr. Hamidi’s other areas of interest include adrenal disorders such as cortical and medullary adrenal tumors, congenital adrenal hyperplasia, pheochromocytoma and paraganglioma, Von Hippel-Lindau syndrome, multiple endocrine neoplasia syndrome, and adrenocortical carcinoma. Her current research projects focus on prolactin-secreting pituitary tumors, as well as cortical and medullary tumors of the adrenal glands. She aims to translate her work in these areas to high-quality, practice-based care and education.

Dr. Hamidi has delivered international and national presentations and published several academic peer-reviewed articles on the topic of neuroendocrine tumors.
