Throughout her nursing career, Ann Lengeling has held many roles. She began as an aide and, as she advanced her education, worked as a licensed practical nurse, and as a registered nurse before earning her bachelor of science in nursing from the University of Iowa. Over the years she’s worked on the inpatient floor and as an emergency room nurse in a hospital on all kinds of shifts, including nights and weekends.

Her most recent role was with Kindred Hospice as Executive Director.  While Ann feels strongly about hospice care, she says she missed providing care for acute patients in the hospital. “My leadership goals led me back to the hospital setting.”

Ann and her husband, Nate, have three children: Grace, Wade, and Nora. The family enjoys spending time together while camping and kayaking.


Leigh Miller assumed the role of Stewart Memorial Community Hospital’s Chief Clinic Officer on April 17, 2023.

Leigh’s role here at SMCH encompasses a wide scope of duties. In general, she directs, supervises and coordinates the overall healthcare operations for McCrary-Rost and Stewart Memorial clinics. This means it’s her job to arrange quality, reliable, safe care in a fiscally responsible manner to ensure future generations have access to that care as well.

Leigh has been a resident of the Stanhope area her entire life, which has created a passion in her for giving back to small communities. Her family is often involved in town celebrations, Lion’s Club, and other events, and currently, she serves as Vice President of the South Hamilton School Board, while her husband Brian is the mayor of Stanhope.
