Arielle M. Myers

Chief Curator

Arielle directs the creative vision of Union Hall, developing all exhibitions, programming, events, and partnerships. She is an advocate and supporter of emerging artists, and brings this passion to Union Hall, working to fulfill our mission of being a true cultural community partner in Denver and beyond. Arielle earned her MA in Art History from CU Boulder, and has previously held positions at NINE dot ARTS, the Boulder Museum of Contemporary Art, CU Boulder, and Paul Kasmin Gallery. In addition to her work Union Hall, she continues to develop her curatorial practice through exhibitions produced independently and collaboratively. When she’s not working with creatives to showcase their work at Union Hall, Arielle is likely to be found on the road with her partner and pup, or working on her garden at home in Denver.
