Charles MacKay (born May 1950, Albuquerque, New Mexico) is an American arts administrator, currently the General Director of The Santa Fe Opera in New Mexico. He is the son of John and Margaret MacKay and a graduate of Santa Fe High School and of the University of Minnesota.
Early experience at The Santa Fe Opera
As a youth, he played the French horn, and played in the orchestra of Santa Fe Opera (SFO) at age 17. He was a volunteer with Santa Fe Opera at age 15, and began to work in administrative capacities with SFO at age 18. He worked at SFO as an orchestra librarian, in the business office and painting stage scenery. Subsequently with SFO, MacKay also held several administrative positions, including box office manager, assistant orchestra manager and business manager, the last position for 4 years.
Involvement with the Opera Theatre of Saint Louis
After leaving Santa Fe, his other administrative positions include a 6-year tenure as director of finance and administration for the Spoleto Festival USA, from 1978 to 1984. For 5 years, he was the manager for the American artists at the Festival of Two Worlds in Spoleto, Italy.
However, in 1984, MacKay became executive director of Opera Theatre of Saint Louis (OTSL), recruited to the post by OTSL's first general director Richard Gaddes. In 1985, MacKay was named OTSL's second general director, after Gaddes stood down from the post. During his tenure, MacKay presided over the growth of OTSL's endowment from USD $682,000 to $18 million, and maintained the company's record of never posting a deficit. He also raised funds for the construction of the Sally S. Levy Opera Center, the company's first permanent administrative facility, which was completed in 2006.
Appointment to The Santa Fe Opera
In November 2007, SFO named MacKay as its third general director, succeeding Richard Gaddes who was retiring. He concluded his OTSL tenure on 30 September 2008, and began his tenure as SFO general director on 1 October 2008.
While he had some involvement in the planning of the 2009 festival season, the 2010 season is based on MacKay's programming and contains nods of appreciation and dedication to John Crosby, SFO's founding director (by opening his season with Madame Butterfly, Crosby's 1957 opening night and the opening night of new 1968 theatre after the 1967 fire) and to Richard Gaddes (by including a Benjamin Britten opera, Albert Herring in the line-up).
