Orchestras Delta David Gier has conducted include the New York Philharmonic, the Philadelphia Orchestra, the Cleveland Orchestra, the Chicago Symphony, the St. Louis Symphony, and the Minnesota Orchestra.

Since 2004, Mr. Gier has been music director of the South Dakota Symphony Orchestra. During that period the orchestra has been lauded for its programming; a series based on the Pulitzer Prize was called “an unprecedented programming innovation” by the Wall Street Journal. The Lakota Music Project, a side-by-side program with SDSO American Indian musicians, was instituted in 2009 and has since expanded to Bridging Cultures, which has engaged Arab, Persian, Chinese, South Asian, Latinx, and Sudanese and Somali refugee communities.

For 15 seasons, Delta David Gier served as an assistant conductor of the New York Philharmonic. He studied at the University of Michigan under Gustav Meier, as well as the Tanglewood Music Center and Aspen Music Festival. He was a Fulbright scholar in eastern Europe from 1988-90.
