ST. LOUIS — Four nursing educators in Saint Louis University’s Trudy Busch Valentine School of Nursing have been honored with a St. Louis Magazine’s 2025 Excellence in Nursing Award. This recognition underscores the dedication and leadership of SLU’s nurse educators in advancing the profession and shaping the future of health care.
In February, the magazine selected five finalists from SLU’s Trudy Busch Valentine School of Nursing for their commitment to teaching, research, and mentorship. Nominees included Geralyn Ochs, associate professor of nursing; Michelle Papachrisanthou, DNP, associate dean of graduate nursing practice; Diana Llamas, assistant professor of nursing; and simulation operations manager; Melissa Holman, adjunct professor of nursing; and Kristin Keller, Ph.D., assistant professor of nursing.
After a rigorous review process conducted by a panel of judges, St. Louis Magazine named four winners at an awards reception held Wednesday, June 4, at the Missouri Botanical Garden. The winners will also be featured in the June/July issue of St. Louis Magazine.

Geralyn Ochs, associate professor of nursing and coordinator of the adult-gerontology acute care nurse practitioner option, has taught at the Valentine School of Nursing for the past 33 years. She led the development and implementation of the first ACNP program in Missouri 24 years ago. Her goal has always been to develop the next generation of highly skilled acute care nurse practitioners who are practice-ready upon graduation to deliver compassionate, attentive, holistic patient-centered care.
On her greatest impact in the field: Ochs participated in the acute care nurse practitioner expert panel discussing the American Nurses Credentialing Center's development of the first adult gerontological acute care nurse practitioner certification exam. She has presented at multiple advanced practice registered nurse (APRN) conferences locally, nationally, and most recently at an international conference for APRNs in Scotland.

Michelle Papachrisanthou, DNP, associate dean of graduate nursing education, is celebrated by her peers for her proactive approach, meticulous attention to detail, and inspiring leadership. Papachrisanthou is instrumental in driving the strategic vision of the school. Under her guidance, the graduate programs have expanded, the curriculum has been refined, and she has played a pivotal role in authoring the Commission on Collegiate Nursing Education (CCNE) Self-Study Report, a comprehensive document used by nursing programs seeking accreditation or reaccreditation, for the Valentine School of Nursing. Papachrisanthou is deeply committed to the school’s core values and is passionate about advancing graduate nursing education.
Two-time Excellence in Nursing finalist: Papachrisanthou was named St. Louis Magazine’s 2018 Excellence in Nursing finalist in the Pediatrics: Non-Neonatal Category. Then, she was recognized for her work as a pediatric nurse practitioner in primary care, serving predominantly medically underserved pediatric populations. She emphasizes the importance of growth, development, and the support of family and community surrounding the child.
In her own words: "Driven by a passion for growth and excellence, I’m dedicated to shaping the future of graduate nursing education at the Valentine School of Nursing with purpose and unwavering commitment."
Diana Llamas – Community/Ambulatory Care

Peruvian native Diana Llamas, assistant professor of nursing and simulation operations manager, has gained invaluable knowledge, skills, and cultural competence from living in Peru, Spain, and the U.S. Llamas is actively involved in developing practical resources to meet mental well-being needs and reduce health disparities among the Hispanic community in the St. Louis area amid a nursing shortage.
Llamas' career began as a nurse in Madrid, Spain, where she grew up. She has experience teaching nursing courses at the SLU Madrid campus with a focus on diabetes and hypertension, making management plans obtainable for the Hispanic community.
"I love the Spanish culture, and the beauty about that is how easy it is to be able to access health care and how well your doctors treat you, plus how much intention they put into taking care of you. That is the trusting relationship that I eventually want to create with my students and patients here," Llamas said in a recent interview with KSDK-TV Ch. 5.
On the job’s most rewarding aspect: As a clinical nurse leader at SLU, Llamas is also committed to training culturally competent nursing students, engaging them in quality improvement projects during their public health clinical rotations at various not-for-profit organizations and clinics. Llamas earned her Ph.D. at SLU and is working to expand the SLU Madrid campus for Master of Science nursing students to increase global health opportunities.

In her own words: "It is a deep honor and privilege to be a part of shaping the next generation of nurses who will embody excellence in nursing care."
