Janne Sirén is the director of the Buffalo AKG Art Museum, a 161-year-old institution with one of the most important collections of American Abstract Expressionism. He was named director in 2013 and guided the organization through a major building project in which the concept of partnership was the cornerstone of the process. Sirén joined Guggenheim President Emeritus Jennifer Stockman and Rail Consulting Editor Joachim Pissarro for a conversation about the history of the Buffalo AKG, the fascinating career path Sirén created to arrive where he is, and the visionary work that goes into building a venerable collection.
