Multispecialty

Our division is focused on preparing the next generation of anesthesia experts through both scholarly and clinical expertise.

Each section of the division has a volunteer leader, or section head, who serves in an administrative role to coordinate educational programs and developing evidence-based clinical care pathways.

Faculty members within our division provide patient care through UNMC's clinical partners. Section leaders also facilitate partnerships with the surgical services of those clinical partners, particularly primary clinical partner, Nebraska Medicine.
