Jennifer Sonney , PhD, ARNP, PPCNP-BC

I currently teach within the Doctor of Nursing Practice program, and have taught the entire spectrum of pediatric advanced practice including pediatric diagnostic health assessment, diagnosis and management of acute and chronic conditions, pediatric pharmacology, and clinical practicum courses. Another focus of my teaching is interdisciplinary training for advanced health professions trainees.

My research expertise is related to pediatric chronic illness, parent-child shared management, and cognitive capacity for children to assume self-management. I primarily focus my research on parent-child dyads; school-aged children with asthma and their parent(s). My study was the first known study to describe the discordance between parent and child asthma and asthma medication beliefs. I am now interested in testing interventions to improve parent-child shared asthma management, particularly medication adherence. I am currently the principal investigator on a pilot study for sleep shared management.

I am a board certified Pediatric Nurse Practitioner, and my clinical practice has centered around community-based pediatric care with a special emphasis on care of children with special health care needs, particularly pediatric pulmonary chronic illness.

Gail Kieckhefer , PhD, ARNP

PPC Nursing faculty Consultant
The Joanne Mongomery Endowed Professor

I currently teach most consistently in the Doctorate in Nursing Practice Program. I have taught advanced health assessment, child behavioral and developmental issues and practicum courses in the pediatric nurse practitioner track.

My research expertise is related to childhood chronic illness; childhood asthma most commonly and sleep in school-age children. I am interested in evidence-based strategies that enable nurses to help families to raise children to be actively participatory in their own health promotion or illness management behavior in developmentally and culturally appropriate ways. As such, my focus is often captured in the term 'shared-management' which is a more life-course appropriate concept than 'self-management' when used in the context of the developing child. I have been principal investigator on several studies examining health outcomes in children with asthma and on a randomized clinical trial examining the effects of a parent education program. In addition, I was co-investigator on two studies that recruited large number of ethnically diverse school-age children with asthma and one testing a model of educating MD residents to work more effectively with parents of children having asthma. Sleep in children has been a recent focus of her work. I and colleagues recently submitted a school-located sleep intervention research application and I am consultant on several child health related interdisciplinary grants.

Carla Salldin , AA

PPC Family/Parent Consultant
A proud parent to a CSHCRN since 1995. Through the birth of my child, I have met many people, where the enrichment to my life has grown immeasurably through learning, partnering and teaching. These priceless opportunities have allowed me to gain extensive experience in resiliency, advocacy, education, leadership and partnering with families and professionals at local, regional and national levels.

A part of my work with the Pulmonary Training Center is to help families bring their voice to the faculty and trainees, enhancing partnerships and improving educational outcomes and to strengthen the foundation of incorporating Family-Centered Care principals into their work through this family partnership. I recruit families to host a healthcare trainee in their home, where the family may bring the trainee to their child’s school, have a dinner outing or a park adventure. I encourage families to participate and become advisors in an arena that is comfortable to them, to think about a partnership in their child’s healthcare and community settings. Families are a valuable asset to improving systems, education, advocacy, at any level, from the Dr. Visit to the national stage of policy making. Find your passion and speak up.

My passion is to bring families and professionals together to enhance outcomes of Family-Centered Care through education and partnership building.
