The Avenir Conservation Center (ACC) at the Denver Museum of Nature & Science is graciously funded through the Avenir Endowment for Conservation. The Avenir Conservation Center works closely with the Anthropology collections and curatorial staff and originating and descendant communities to steward belongings with the utmost respect and sensitivity. The work of the ACC strives to deepen relationships while developing advanced conservation treatment methods to improve the quality of care of the collections.
Mission
The mission of the Avenir Conservation Center is to develop a facility that generates collaborative and innovative collections care and research; serve as a resource for other institutions and individuals, and mentor a new generation of conservators and museum professionals from diverse and wide-reaching backgrounds. We will join the forward-thinking people and organizations that model the changes we embrace.
Vision
The Avenir Conservation Center is committed to compassionate and scholarly conservation initiatives that are deeply rooted in shared learning. We strive to model excellence as well as de-center historical perspectives on ownership, care, and preservation of belongings housed in Museum collections by partnering with originating and descendant communities to amplify their beliefs and desires. We resolve to honor diverse cultural protocols during all phases of our work.
What is cultural heritage conservation?
Cultural heritage conservators are responsible for the long-term care and stewardship of artistic, historic, and cultural materials guided by a code of ethics intended to protect the integrity and authenticity of works of art and cultural heritage. Conservators are professionals with advanced academic degrees in art conservation.
Conservators use observation, documentation, consultation, scientific analysis, and research to understand materials and methods of manufacture. This knowledge guides the care, handling, and treatments of collections. This process may lead to returning indigenous belongings to communities from which they originated.

Casey Mallinckrodt, MA
Casey Mallinckrodt is an objects conservator with experience working on a wide range of materials from contemporary chocolate sculpture to Ancient Egyptian painted coffins. Her greatest interest though, is with collections of material culture and using community collaboration, technical analysis, and cross disciplinary research to deepen the understanding of these objects and to guide thoughtful stewardship. Casey has been privileged to work on collections of Native American material culture and the arts of Central and West Africa, and South Africa. She is excited to work with DMNS museum colleagues across divisions and with the larger community, and to develop learning opportunities for people entering the discipline.
Casey received a master’s degree in conservation from the UCLA/Getty Program in the Conservation of Archaeological and Ethnographic Materials, and an MFA is sculpture from the Yale School of Art. Before joining DMNS Casey was the first objects conservator in the Wadsworth Atheneum Museum of Art’s 180-year history and prior to that was part of a conservation-curatorial team at the Virginia Museum of Fine Arts carrying out the technical analysis, study, and conservation of historic arts of Africa.
Casey is a trustee of the College of the Atlantic in Bar Harbor, Maine.

Ella Thomas
Ella joined the Denver Museum of Nature and Science in 2024 as a Conservation Assistant to learn more about the field of Conservation and study under accomplished Conservators before pursuing a graduate degree. She received her BA with a double major of Art History and Chemistry from the University of Virginia. Before coming to the Museum, she worked in Museum collections in a variety of roles, most recently at the University of Virginia’s Special Collections Library as a Collections Assistant for the Fine and Decorative Arts Department.
Ella is interested in using this role to expand her knowledge of conservation while getting valuable experience working in a lab setting and working directly with objects of cultural heritage. She also looks forward to starting the Winterthur/ University of Delaware Program in Art Conservation in the fall of 2026 with anticipated graduation in 2029.
Anneliese Pesce
Anna joined the Avenir Conservation Center at the Denver Museum of Nature & Science in January 2026, primarily to work on the deinstallation of the North American Indian Cultures Hall. Her work with museum and science centers began at Fiske Planetarium at the University of Colorado, Boulder, where she discovered a passion for working in a museum setting. She has since worked with museum collections at the University of Colorado Natural History Museum and the Aurora History Museum.
Anna deeply enjoys working with Anthropology collections and is grateful to have the opportunity to learn more about the intersection between conservation practices and collections management strategies, as well as how Indigenous knowledge informs care for cultural heritage objects. She is aiming to deepen her knowledge of conservation as a field, as well as expand her experience with large anthropology collections, before attending a graduate program.
