After 8 years of nursing practice, she became a nursing instructor at OHSU in the fall of 2019.

Caldwell Tiffany

Tiffany M. Caldwell, MSN, RN,  Clinical Instructor

After receiving her Master’s degree in nursing education in 2016 she has had the privilege to work with undergraduate nursing students in simulations providing a safe learning environment to promote safe, effective care for patients. She finds it very rewarding being able to witness the growth and development of students over the course of their undergraduate program of study. In addition, she has gained a key interest in Motivational Interviewing as a communication technique to empower nursing students and healthcare providers to talk to patients about their health as MI can significantly influence personal motivation for behavior change and ultimately improve patient health outcomes.

Smith Robynnelle

Robynnelle Smith, BS, MA, DNP Student, Class of 2023

A dual diagnosis therapist by training, she specializes in substance use and mental health disorder treatment and crisis intervention services. She currently holds a CADC III certificate and LPC and LMHC licenses on sabbatical status while attending the DNP program at OHSU.  She is honored to be involved with this research as she believes supporting our older adult population in remaining independent is an essential service often ignored in mainstream culture.


Miles White, BSN student, Class of 2022
Research Staff

After years of working as an organic farmer striving to feed communities with healthy food, he began to pursue his Bachelor of Science in Nursing at OHSU. As a third year in the BSN program, he is interested in both mental health and working with older adults in rural settings. These interests have led him to apply and accept a position in the VA Nursing Partnership program completing his clinical hours within the veteran population. He feels fortunate that he can use his life and clinical skills to further assist his team to help older adults prevent falls and fall-related injuries. He hopes to help bridge the gap between generations through honest, open communication and support.
