Our Providers

Margaret A. Eagan, MD

Dr. Eagan grew up in West Hartford, Connecticut and was instilled early on with a fascination for the human body. She decided to pursue medicine and quickly found focus. Her deep interest in the complexity of a single human cell compelled her to study the chemical signals that determine a cell’s ultimate outcome. This lead her to specialize in Endocrinology — the study of glands and hormones of the body and their related disorders — and later Metabolism — the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life.

Dr. Margaret Eagan earned her Bachelor of Science degree in Biology at Georgetown University in Washington D.C. She attended medical school and completed her internship and residency at the Georgetown School of Medicine. After residency she moved to Denver and completed her fellowship in the field of Endocrinology and Metabolism at the University of Colorado Health Sciences Center specializing in osteoporosis and women’s issues.
