Krishan Oberoi, Ph.D. – Founding Director & Principal Guest Conductor

Krishan is the founding Artistic Director of SACRA/PROFANA. Hailed for his “visionary direction” (San Diego Story), Oberoi has been an ardent champion of 20th and 21st century music, empowering choruses to tackle challenging works by such composers as György Ligeti, Arnold Schoenberg, and Ernst Krenek. Oberoi has emerged as a notable proponent of living composers, initiating regional premieres of works by Nico Muhly, Sara Kirkland Snider, and Pulitzer Prize-winning composer David Lang. In 2014, Oberoi conducted the world premiere recording of David Lang’s when we were children, a piece dedicated to the Glimmerglass Opera. He has been at the vanguard of collaborative, interdisciplinary performance, working frequently with filmmakers, choreographers, and visual artists to expand audiences by creating innovative concert experiences. Oberoi holds degrees from Yale University and New England Conservatory, and recently defended his doctoral thesis to earn his Doctor of Musical Arts degree at Boston University.
