Susan Pena- Almazan, MD

Dr. Susan Pena‑Almazan is a pediatric endocrinologist at Dayton Children's who cares for infants, children and teens with hormone conditions that affect growth, development and daily life. She treats diabetes (type 1 and type 2), growth concerns, early or delayed puberty, and thyroid and adrenal disorders. Dr. Almazan explains complex hormone conditions in clear, simple language so families feel informed and confident about their child’s care.

Dr. Almazan believes her role is to be a trusted partner for patients and families, offering balanced information, encouragement and practical support. She is especially passionate about helping young people with diabetes and endocrine disorders transition smoothly into adult care. What she finds most rewarding is building long‑term relationships and supporting patients from diagnosis in infancy through young adulthood—watching them grow healthier, stronger and more independent along the way.
