During her studies in Los Angeles, Conwill worked as an arts educator and activities coordinator for the Hollyhock House. After her graduation in 1980, she became the Deputy Director at the Studio Museum in Harlem and subsequently served as Director from 1988 until 1999.[2] Conwill described her time at the museum and the meaning of the institution for the Black community at the occasion of their 50th anniversary:
The Museum was everything. It was a community center, an artists’ circle, a forum for amazing conversations and intellectual discussions, a meeting ground, a vibrant place that had a lot of owners. I think this has stayed true for the Museum. I saw it as a center of life not just in Harlem, but also of New York, and, in some ways, the center of a much larger black world and art world.
