Leadership performance outcomes reflected existential phenomenological methods in an account of museum volunteer perceptions. Volunteers developed personal transformation leadership during the production of a museum digital collection, a purposeful project, creating an archive, a digital repository for video media, supporting mediated meaning, reflective thinking, and mindset coaching strategies. Evidence of leadership outcomes advanced museum education outreach for personal and community transformative social change. Continuous interactions included independent volunteers forming an interdependent working group and creating successful leader volunteers. The Buffalo Bill Center of the West housed the archive, as perceptions of leadership reported evolving leadership. The nature of perceptions involved thematic investigation, expanding potential for purpose, time, expertise, commitment, dedication, and collaboration in transformation leadership.
