About The Provider

Dr. Stanciu was born and raised in Bucharest, Romania, where she earned her Doctor of Medicine from Carol Davila University. She continued her medical training with an internship in general surgery and a general medicine residency in Bucharest, Romania. Dr. Stanciu moved to the United States in 1997 to complete an Internal Medicine Residency at Cook County Hospital in Chicago.

Dr. Stanciu is board-certified in endocrinology, diabetes, and metabolism, and internal medicine. She has expertise in parathyroid, osteoporosis, and other metabolic bone disorders (including rare bone disorders).

Dr. Stanciu believes in engaging patients in learning about their disease and available treatment options to achieve the best possible outcomes. She aims to make patients comfortable with their treatment decisions, knowledgeable about the disease process, and encourage them to actively participate in their healing by promoting a healthy and active lifestyle.

“I am thorough in my evaluation so I can understand the root cause of the disease, find the appropriate treatment option, and explain to the patient in easy-to-understand language. I love to see the patient getting back to an active lifestyle.”

When she is not working, Dr. Stanciu enjoys the beautiful weather and mountains of Colorado, where she can be found hiking and camping in the summer and skiing in the winter. She has two daughters, one granddaughter, and three grandsons.

    She takes any anxiety out of the process of determining how to proceed. We are straightforward and candid with each other and thus, reach decisions based on facts that have been gathered. She explains choices with possible risks and probable outcomes. She teaches me so much and I can ask her anything. This comfort level has built great trust for me as she is invested in her goals for my good. She can also tell me to get going on exercise (again) because it will make a difference. I am... and it does! Thanks- I needed that!
