Monica Haley Heenan has been promoted to chief ambulatory executive at Children's Memorial Hospital. Heenan, 52, has more than 25 years of clinical operations and project management experience, most recently as chief of ambulatory services and medical management at Children's Memorial, where she has improved patient access and directed the conversion to electronic medical records in the ambulatory practice. Heenan and new Chief Patient Care Services Officer Michelle Stephenson, who will remain chief nurse executive, will split the responsibilities of the former chief operating officer to help in the transition to the new Ann and Robert H. Lurie Children's Hospital, which opens downtown next year. Before coming to Children's, Heenan was vice president of patient services and chief nursing officer at Thorek Hospital and Medical Center and ambulatory services director at Columbus-Cabrini Medical Center. She has a B.S. in nursing from Northern Illinois University and a master's of public administration from Roosevelt University.
