Philosophy of Care

Caring for children and their families is a unique privilege we have as pediatricians and a strong partnership is essential. By listening, collaborating, and learning about the patient and their family, we can help guide families understanding of disease processes and understand various treatment options. We are able to provide support in the management of a wide spectrum of lung problems from common childhood conditions to complicated rare lung diseases. Whether in the inpatient or outpatient setting, we are fortunate to be a part of children's journey to health and wellness. UC Davis offers a dedicated team of physician subspecialists, nurses, respiratory specialists, child life specialists, and social works all prioritizing pediatric health. I am honored to work with this inspiring group of individuals and with the patients and families in our community to optimize the management of respiratory diseases in children.

Clinical Interests

Dr. Willen is a board certified provider in Pediatric Hematology/Oncology as well as Pediatric Pulmonology. She has a clinical interest in asthma, obstructive sleep apnea, and pulmonary vascular diseases as well as lung complications for patients with sickle cell disease such as acute chest syndrome, pulmonary hypertension, and chronic lung disease of sickle cell.

Research/Academic Interests

Dr. Willen's research focuses on improving the care for children with pulmonary complications of sickle cell disease, specifically the management of asthma and identification of risk factors for acute chest syndrome. She also has interest in lung changes and complications following chemotherapy and radiation treatments.
