Looking to escape the snowy winters of New England, Dr. Andrew Little moved west in 1995 shortly after graduating from Yale. With a Bachelor of Science degree in Molecular Biophysics and Biochemistry, he joined a California-based biotech company as a research scientist. He was inspired to be a physician by participating in the clinical application of basic research. “I am fascinated by our ability to increasingly apply scientific knowledge to help people maintain, or regain, a healthy lifestyle. The opportunity to participate in the development of new medical frontiers is a privilege I take very seriously.”

At Barrow Neurosurgical Associates, Dr. Little focuses his practice on minimally invasive approaches to treating pituitary disorders, skull base lesions, brain tumors, and spine disorders. His addition to the pituitary team helps establish BNI as the premier neuroendocrine center in the Southwest. It is his belief that a multidisciplinary team approach to pituitary disorders ultimately best serves the patient and results in the best possible treatment outcomes.

Dr Little has published extensively in peer-reviewed medical journals and given presentations at national and international conferences. His research interests include pituitary surgical outcomes and the natural history of untreated pituitary tumors. He is the Co-Director of Barrow Interdisciplinary Skull Base Program and Co-Director of Barrow Pituitary Center.
