Chizimuzo (Zim) Okoli, PhD, MPH, MSN, PMHNP-BC, FAAN
Nominated by Lora Peppard, PhD, DNP, PMHNP-BC
For Chizimuzo “Zim” Okoli, psychiatric-mental health (PMH) nursing is about seeing patterns of suffering and actively responding to create positive change. His passionate vision and innovative activism have advanced the scope and impact of PMH nursing through sustained national leadership, scholarship, and an unwavering commitment to service.
Catapulted into the field during his very first nursing school psychiatric-mental health nursing rotation, Zim saw the depth of human need. “I was drawn to the profound suffering people can have when living with mental and behavioral health challenges,” he said. “I decided right on that spot that I was at home in psychiatric nursing.”
Zim’s transformative contributions to PMH nursing span decades of clinical practice, research, education, leadership, and policy. A professor at the University of Kentucky (UKY) College of Nursing, and founder/executive director of the UKY BH WELL (Behavioral Health Wellness Environments for Living and Learning) program, Zim has built a career translating evidence into meaningful change and treatment for people with mental illness.
With a focus on addressing substance use, particularly tobacco use, among psychiatric populations, Zim explains, “Tobacco use is the leading cause of preventable death among those with mental illness, significantly reducing life expectancy. When individuals stop using tobacco, in addition to the physical health benefits, they also have lower depressive and anxiety symptoms – their mental health improves. It is hard work, but it’s extremely rewarding because I know we’re saving many lives.”
Zim’s research and bold, evidence-based innovations have helped behavioral health systems understand how tobacco use compromises recovery, interferes with medications, and worsens health outcomes. His leadership has expanded access to tobacco treatment for thousands of psychiatric hospital patients, increased clinician confidence, skills and engagement, and driven new community partnerships to shape smoke-free behavioral health facilities. This work is significant. Change like this challenges and disrupts longstanding norms and is more effectively integrating mental and physical health care interventions.
Zim also designs and implements unique wellness interventions for people living with mental health and substance use disorders, including community-based “Quit & Win” tobacco-free initiatives to encourage sustained cessation efforts. He emphasizes that implementation matters. “We often can see and know what works. We shouldn’t forget to actively work to translate those innovations into practice. Ultimately, we want to create impact, sustained impact that changes lives.”
This philosophy also shapes his role as an educator and mentor. Inspired by his mother, also a nurse educator, Zim teaches PhD students, works to create new professional pathways and publication opportunities, and mentors emerging PMH nurses, practitioners, educators, and scientists. He describes mentoring as one of the deepest joys of his work: walking alongside students from early uncertainty through theses, dissertations, graduation, and eventually independent leadership.
People know and experience Zim’s humbleness and heart with each interaction. His approach is consistently patient, relational, and identity-affirming. He works to foster the growth of emerging PMH nurses with generous, genuine support. He remembers a mentor telling him, “No matter what you choose to do, never forget you are a psych nurse.” That message stayed with him, and he now infuses the same kind of grounding into his students. “I’m able to always remind them who they are at their core,” he said.
In APNA, Zim “found his professional home” where he could serve. He stepped forward to serve on and chair the APNA Scholarly Review Committee for a few years , helping to review scientific content submitted for each annual conference. He served as APNA president, where he worked to guide the profession toward his vision of increased access, de-stigmatization, and evidence-based care. As president, Zim advanced IDEAS: inclusivity, diversity, equity, access, and destigmatization, values he describes as “undeniably essential pillars of PMH nursing”.
Zim actively elevates PMH nursing expertise through numerous publications in peer-reviewed journals and by delivering training and presentations all throughout the world. Zim’s recent scholarship as a Fulbright Specialist in Taiwan uniquely focused on migrant mental health and culturally responsive care for individuals, families, and communities.
Across every dimension of his career, Zim returns to a philosophy inspired by Florence Nightingale: when repeated patterns of need appear in society, they serve as a calling for nurses to act. For Zim, those patterns are not abstract. They are patients trying to recover, systems ready for change, students finding their voice, and communities in need of better care.
“When I see the patterns, there is meaning,” he said. “And if there’s meaning, there is purpose. Whatever I do to help address those issues, it’s a life worth living.”
