In a dairy barn far from any hospital, Natalie Rejto moves between the milking parlor alongside workers who can diagnose a cow’s health with a glance. She’s collaborating with veterinarians and industry leaders on infection prevention, but here the experts are the farmers themselves—and Natalie has learned that the best solutions emerge when she listens to what they already know.
The scene captures the essence of Natalie’s remarkable journey, from bedside nurse to pioneering researcher whose work transcends traditional boundaries between human health, animal welfare, and environmental sustainability.
“Nurses have a very unique perspective,” Natalie reflects. “Especially working in the hospital setting, that direct interaction, patient teaching, the nursing approach… it can be really valuable in research.”
Unlikely Beginnings
Natalie’s path to becoming a researcher wasn’t one she initially envisioned for herself. Growing up in Tucson, Arizona, in a low-income household, her educational journey had been unconventional. She had to withdraw from high school during her junior year but earned her GED the following year. Completing her education was a significant achievement. When she became a nurse in 2008 after earning her BSN from the University of Arizona, she considered it the pinnacle of her educational journey.
“I never considered going back to school,” she admits. “I didn’t think it would be an option for me.”
Her trajectory changed in 2015 while working at Seattle Children’s Hospital, where she became a nursing bioethics liaison. This role awakened her passion for worker health and well-being advocacy. A pivotal conversation with Dr. Elaine Walsh, a faculty member in
Child, Family, and Population Health Nursing at the University of Washington School of Nursing, opened her eyes to new possibilities.

“She really encouraged me to pursue further education based on my interests and my overarching goals in life,” Natalie says.
After speaking with PhD students and connecting with faculty like Butch de Castro, whose work aligned with her interest in worker health, Natalie applied to the doctoral program. She completed her PhD in June 2024, focusing on multidimensional sleep health among nurses and investigating whether sleep hygiene can modify the impacts of shift work.
One Health: A Holistic Approach
Today, Natalie serves as a postdoctoral researcher at the University of Washington’s Center for One Health Research (COHR), working with Dr. Peter Rabinowitz and Vickie Ramirez. The center’s philosophy—”healthy people, healthy animals, healthy environment”—deeply resonates with Natalie’s vision.
“It really aligned with a nursing model of care,” she explains. “You take into account the person within their built environment, natural environment, animals… there’s not these little separations. It all exists together.”
Her current research exemplifies this interconnected approach. Working with dairy farms in Eastern Washington, Natalie and her colleagues use a collaborative approach, partnering with industry, workers, and experts across disciplines, including veterinarians. Together, they develop practical infection prevention strategies to protect workers from zoonotic diseases like COVID-19 and avian influenza.
The research involves visits to farms to understand daily tasks and evidence-based technologies already in place and build partnerships with industry and workers. In collaboration with the Pacific Northwest Agriculture Safety and Health (PNASH) center, they conducted a survey and are developing modules focused practical strategies to promote worker health funded by a Safety and Health Investment Program grant from the Washington State Department of Labor & Industries.
Healing Across Communities
Perhaps most meaningful to Natalie is her volunteer work with Seattle’s One Health Clinic, which serves populations experiencing homelessness and their companion animals.
“The work being done at the One Health Clinic addresses human care and animal care and really acknowledges that human-animal bond and shared environment,” she says. “Building trust populations among people experiencing homelessness is really special and sustaining.”
In uncertain times in academia, Natalie finds this work grounding and inspiring. It exemplifies the principle that healing transcends traditional boundaries—between species, environments, and communities.
A Bridge Between Worlds
What makes Natalie’s approach unique is her ability to bridge different worlds: the clinical experience of being a bedside nurse with the analytical mindset of a researcher; the urban healthcare setting with rural agricultural communities; human medicine with veterinary science. This transdisciplinary collaboration has become one of the most rewarding aspects of her work.
“With research, especially coming after 15 years as a bedside nurse, I felt very comfortable in that kind of collaboration and communication,” she reflects. “It’s been just this amazing opportunity to hopefully bring what I’ve learned from nursing science to be able to work with folks in the Center for One Health.”
She points out that nurses have already witnessed the power of the human-animal bond in healthcare settings, through experiences with pet therapy and emotional support animals in hospitals.
Advice for Future Nurses
For aspiring nurses considering their career paths, Natalie offers encouraging words:
“Nurses do incredible work. The work is very challenging. You’re thinking on your feet and synthesizing lots of information into practice, and it can seem really daunting and intimidating, at least it was for me, the thought of going for higher education. But I would say if you can do nursing and you want it and you have the passion for it; you can do higher education. From my experience, the faculty are really supportive and want you to succeed.”
Her story demonstrates that nursing can lead to unexpected and fulfilling paths, even to dairy farms in Eastern Washington or clinics serving populations experiencing homelessness and their companion animals. It’s a testament to how nursing’s holistic approach to health can extend far beyond hospital walls, creating healing across all boundaries.
