Meet the Institute for Population Health advisors
The IPH is guided by an advisory committee composed of Creighton faculty and staff representing a cross-section of the University community involved in population health work in some way, along with clinical partner representatives from Nebraska and Phoenix. The committee helped establish the guiding vision and mission for the Institute and continues to provide leadership and guidance through quarterly meetings with IPH team leaders. Committee members also contributed to the development of a five-year strategic plan, which provides clear goals and direction for the IPH team. In each edition of the IPH Access newsletter, we will introduce you to two members of the advisory board.
Jason Marshall, PhD
Jason Marshall, PhD, assistant professor of management in the Heider College of Business, joined the IPH advisory board in summer 2023, participating in the board’s inaugural planning meetings that established its vision and mission. A longtime advocate for community health, Marshall brings experience from his previous service with Live Healthy DeKalb County in Illinois and as chairman of the board for The BRIGHT Coalition, a nonprofit focused on improving population health across a 10-county region in southcentral Kentucky.
Marshall said his interest in population health began as a personal pursuit of healthy living but soon grew into a broader understanding of the role social determinants play in shaping health outcomes.
“Health is not merely an individual choice,” he said. “It’s influenced by the environments and systems we create. The IPH’s commitment to education, research, and advocacy aligns with my passion for advancing health equity.”
He views the IPH as a way for Creighton to live out its Jesuit values by caring for the whole person and forming agents of change.
“Health inequities are not reserved for developing nations — they exist in our own backyards,” he said. “By bringing together multidisciplinary expertise from across Creighton’s schools, my hope is that our work in the IPH can radiate outward to improve health outcomes for people throughout Nebraska and Arizona, and beyond.”
Holly Sak, EdD
Holly Sak, EdD, assistant professor in the Creighton College of Nursing, joined the IPH advisory board in May 2024. A public health nurse, educator, and advocate, Sak said her decision to join was rooted in her belief that “change happens at the speed of trust.” Building authentic, trust-based relationships, she said, has been central to her work in public health and community engagement, making the board’s mission a natural extension of her values.
“The IPH’s mission connects directly with what drives me every day: advancing health equity and creating opportunities for people to live healthy, full lives,” Sak said. “The board brings together a diverse and talented group of people, all passionate about improving health outcomes through collaboration, inclusion, and action.”
Sak views the IPH as a living example of Creighton’s Jesuit mission in action — a connector linking academia, healthcare systems, and community organizations to address complex health challenges. “Population health work reminds us that improving health isn’t just about hospitals and clinics,” she said. “It’s about where people live, learn, work, worship, and play.”
For Sak, being part of the IPH board represents the intersection of service, scholarship, and community — “the space where real transformation begins.” Recently, she deepened her involvement by serving as a Champion for the IPH Population Health Collective to help grow Creighton’s interdisciplinary community committed to health justice.
Jillian Wallen, BDS, MS
Jillian Wallen, BDS, MS, dean of the School of Dentistry and professor of pediatric dentistry, has served on the IPH advisory board since its inception in 2023. Wallen brings a unique perspective to the board as a member of a healthcare profession that is typically not included in interprofessional healthcare efforts. She said she is excited to bring the idea of oral health as part of whole healthcare to the board in discussing the goals and strategies of the IPH. She sees the board’s primary role as guiding and supporting the institute in its efforts.
Wallen also said she is pleased that the IPH has brought Human Centered Design (HCD) to Creighton.
“HCD was part of the work I did at a previous institution,” she said. “HCD certainly can benefit the patient experience in healthcare, but it can also be broadly applied across the schools and colleges to benefit the community.”
Wallen said she also participated in HCD from a different perspective — as a patient advocate as a parent with a child with special healthcare needs.
“I’m excited to see how it evolves here on campus,” she said. “I can speak from experience and share perspectives from different lenses. It’s nice to have an opportunity to reframe the conversation; to ask questions like, ‘How can we use this in the healthcare space?’ and ‘How can we listen to the community we serve to find out what they need?’”
Monica White
Monica White, assistant professor of cultural and social studies and director of the social work program, is a licensed master social worker and licensed mental health practitioner. White joined the board because she was excited by the Institute’s focus on innovation in healthcare delivery to increase access.
“The IPH is important because Creighton is a leader in educating the workforce,” White said. “The most obvious are those students who will be direct healthcare providers. The less obvious, but equally important, are the many others who will become community leaders who help form the network of resources focused on holistic health, mental health and well-being. The IPH helps synthesize and mobilize many moving parts into sustainable systems-level change.”
The board, White continued, provides a space where people from many perspectives can share ideas, including community, medical providers, researchers, academics, clinicians, staff and more.
“The goal of these ideas is action,” she said, “and trying to sort through a complex medical world with strategies that will make a measurable difference for patients and communities.”
