About Eileen A. Baez-Irizarry


Eileen Baez-Irizarry, MD is a pediatric endocrinologist with a wide array of interests including management of type I and type 2 diabetes mellitus, adrenal gland disorders, and hypopituitarism. She is particularly passionate about caring for children with genetic conditions such as Turner, Williams, and Noonan's syndromes. Dr. Baez is a member of the Pediatric Endocrine Society and is active in multiple research studies regarding the natural progression of type 1 diabetes mellitus, insulin analogs, and growth hormone therapy.

Dr. Baez also supports patients through the St. Luke’s Essence Clinic, which brings together experts in pediatric urology, pediatric endocrinology, genetics, and psychology to care for infants, children, and adolescents with disorders of sexual differentiation. The clinic also provides care for transgender youth, providing gender-affirming treatment and mental health services for patients and their families. 

Dr. Baez is originally from Puerto Rico, and completed her bachelor's degree in biology at the University of Puerto Rico before traveling to complete her medical education. She earned her medical degree at Autonomous University of Guadalajara in a joint program with New York Medical College, graduating in the top five of her class. She later completed a pediatric residency at the Women and Children's Hospital of Buffalo where she received the Daigler Chief Resident’s Award, given to the senior resident who best exemplifies a commitment to life-long learning and caring for children and adolescents in pediatrics. 

Next, Dr. Baez completed a fellowship in pediatric endocrinology at the Children's Hospital in New Orleans where she conducted focused studies on advanced glycation end products and how they may be used to identify individuals with type I diabetes mellitus who are at higher risk for complications with focus on cardiac, renal, and fatty liver disease. During this time, she was awarded the Pediatric Fellow Teaching Excellence Award in recognition of her outstanding teaching and mentoring skills. To this day, she enjoys hosting medical residents in clinic on a regular basis. “It is our responsibility as seasoned physicians to provide ongoing education for the newer generations. It is essential to translate basic clinical skills and encourage a heightened responsibility for medical decision making.” 

Dr. Baez practiced in South Carolina for many years before moving to Idaho. While there, she served as medical director for the largest diabetes mellitus camp in the state for three consecutive years. She also hosted diabetes management education sessions for the community with the goal of empowerment. She is passionate about educating and empowering her patients to succeed when managing a chronic health condition.
