Isabel Casimiro, MD, PhD

Clinical Instructor of Medicine

Isabel Casimiro, MD, PhD, is a highly skilled endocrinologist who diagnoses and manages a wide range of endocrine conditions. Dr. Casimiro delivers comprehensive care for patients with Type 1 diabetes, Type 2 diabetes, lipid disorders (such as dyslipidemia, hyperlipidemia and hypercholesterolemia), transgender medicine, cardiovascular endocrinology and more.

As a physician-scientist, Dr. Casimiro is committed to using research to improve the lives of her endocrine patients. Currently, she is exploring how macrophage (a type of white blood cell) activation can cause inflammation that can ultimately result in metabolic disease. By investigating the 12/15-lipoxygenase enzyme in macrophages, Dr. Casimiro is working to understand how this pathway contributes to obesity and insulin resistance so she can offer better treatment options. Dr. Casimiro’s research has been published in several highly respected, peer-reviewed journals, including Obesity Science and Practice, Atherosclerosis and Physiological Reports.

Dr. Casimiro also has extensive experience providing gender affirming hormone therapy and improving education regarding transgender medicine for endocrinology fellows. Her work with transgender patients has been published in the Journal of the Endocrine Society and Transgender Health.

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
