Jennifer Buffenbarger, Ed.D., originally from Wales, United Kingdom, brings a deep passion for nursing—one that has guided her for over 30 years. Early in her journey, she told her instructors, “I eventually want to give back what was once given to me.”

After earning her Master of Science in Nursing (Nursing Education) and a Doctorate in Education (Higher Education and Adult Learning), Buffenbarger transitioned into academia, where she now teaches across both undergraduate and graduate programs. Her courses include Health Assessment, Nursing Fundamentals, Mental Health Nursing, Population-Focused Care, and Chronic Illness. She also leads the final Master’s Project course and teaches interdisciplinary subjects such as holistic health, health promotion and program development, and first-year seminars.

In recent years, Buffenbarger has increasingly focused on mental health nursing. She developed a 10-week evolving case study that simulates the lived experiences of individuals with mental illness. This innovative approach promotes empathy and enhances students’ therapeutic communication skills.

Fulfilling her long-standing promise to give back, Buffenbarger now offers her students the same compassion she once extended to her patients. For her, the role of educator is just as rewarding as being a nurse—both grounded in the intentional act of caring.
