Eliza B. Geer, MD
Endocrinologist
My Role at MSKWe post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

About Me
- Medical Director, Pituitary & Skull Base Tumor Center
I am an endocrinologist who specializes in caring for people with pituitary and neuroendocrine diseases.
I am the Medical Director of Memorial Sloan Kettering’s Multidisciplinary Pituitary & Skull Base Tumor Center, located at Memorial Hospital in Manhattan. At this center, we bring together experts from many areas — including neurosurgery, head and neck surgery, endocrinology, radiation oncology, and medical oncology — to offer comprehensive care for people with pituitary and skull base tumors.

Our multidisciplinary pituitary team provides personalized surgical and medical treatment for people with pituitary and skull base tumors, including prolactinomas, growth-hormone secreting adenomas (acromegaly), and Cushing’s disease. Our overall goal is to improve and advance the care of people with these conditions.
My research interests focus on achieving a better understanding of how and why pituitary tumors develop, and characterizing long-term outcomes in patients with Cushing’s disease. I have conducted a number of studies investigating body composition, adipose tissue regulation, and appetite in patients with Cushing’s disease, and I am involved in clinical trials investigating new medical therapies for patients with Cushing’s and acromegaly.
I completed my internship and residency at the NewYork-Presbyterian Hospital/Columbia Medical Center. I was a fellow in endocrinology and metabolism at the Icahn School of Medicine/Mount Sinai Medical Center, after which I was a member of the faculty for ten years. I am currently an associate professor of medicine and an active member of the Endocrine Society, the Pituitary Society, and the American Association of Clinical Endocrinologists.
An endocrinologist (EN-doh-krih-NAH-loh-jist) is a doctor with special training in endocrine problems. These disorders affect glands and organs that make hormones, and include diabetes, infertility, and thyroid, adrenal, and pituitary gland problems.
