Please help welcome our new PA Hannah, we are so excited to have her join our team! 🩺💉

Hannah Burge grew up in Brady, Nebraska, and earned her Bachelor of Science degree from Midland University in Fremont, Nebraska, where she also played soccer. She went on to graduate from Union Adventist University with her Master of Physician Assistant Studies in 2025 and is board certified by the National Commission on Certification of Physician Assistants.

Hannah was drawn to general surgery for its hands-on nature and the opportunity to make a meaningful difference in patients’ lives. She is dedicated to providing compassionate, patient-centered care and strives to connect with each patient to understand their individual needs and concerns. Having grown up in a small town, she also feels a strong connection to rural communities and looks forward to serving patients in similar areas.

Hannah lives in Lincoln with her husband. In her free time, she enjoys serving at her church, spending time with family and friends, reading, staying active, and being outdoors.
