Rosie Siemer is an expert in museum audience development and membership strategy.

Although her expertise is rooted in more than a decade of research, education, and field experience, she possesses a unique understanding of what makes museum geeks tick because she is a museum geek—she has visited more than ninety museums in twelve countries (and counting!).

Rosie’s passion for enhancing and promoting the museum experience inspired her to launch FIVESEED, a research and strategy partner to arts and culture and conservation organizations worldwide. Under Rosie’s leadership, FIVESEED has guided dozens of museums in the development and execution of data-informed strategies that deepen audience engagement and build long-term financial sustainability. She has provided consulting services to a number of internationally respected cultural organizations, including the Louvre Abu Dhabi, Museum of Science Boston, Saint Louis Art Museum, Desert Botanical Garden, Space Center Houston, Smithsonian’s National Zoo, History Colorado, Mt. Cuba Center, and the Murphy Arts District.

Sharing her expertise to help museums thrive, Rosie frequently facilitates workshops on audience development and speaks on the topics of building empathy, choice architecture, and the future of membership. She also enjoys sharing her time with professional, cultural, and community organizations and has served on a number of boards, including the Denver Police Museum, World Trade Center Denver, and the American Marketing Association. Rosie is a graduate of Metropolitan State University of Denver where she earned dual degrees in Marketing and Business Management.

Museum Membership Innovation: Unlocking Ideas for Audience Engagement and Sustainable Revenue is the culmination of nearly a decade of research. Rosie also co-authored Membership Marketing in the Digital Age, a comprehensive resource guide for cultural membership professionals. When she’s not researching, writing, or museum hopping, Rosie enjoys Scotch-tasting and watching sci-fi movies.
