The spirit, drive and fierce sense of pride of those who made Tulsa boom into an important city also encouraged a rich cultural heritage, leading to the formation of the Tulsa Opera Club on December 1, 1948. As opera gained popularity, so did the organization. In 1951, the directors agreed that the name "Tulsa Opera Club" sounded too amateurish to be taken seriously. On April 21, the organization became "Tulsa Opera Incorporated," as it is still officially known. Tulsa Opera presented light operas and operettas twice yearly until November, 1955 when a major milestone was reached. With its presentation of Madama Butterfly, featuring imported professional singers for all principal roles, Tulsa Opera successfully transitioned to grand opera and made a giant step toward national prominence. Today, Tulsa Opera, the 18th oldest opera company in North America, produces three grand operas each season, and has been named one of America’s top 10 favorite regional opera companies by Opera News. Mainstage productions are held at the Tulsa Performing Arts Center. Tulsa Youth Opera, inaugurated in 1997, is part of Tulsa Opera’s extensive educational programs. Tulsa Opera is a member of OPERA America. Performances and education programs are provided to the greater Tulsa area, with additional programs provided for adults and children statewide. Tulsa Opera draws its audiences from the region that includes Oklahoma, Arkansas, Kansas, Missouri and Texas. Tulsa Opera is fortunate to have almost 700 dedicated volunteers and a Board of Directors is currently comprised of 55 men and women who represent various businesses and organizations in Oklahoma. They have a passion or appreciation of the arts as well as a dedication to the betterment of Oklahoma. All volunteers work in conjunction with a professional staff to sponsor and coordinate activities ranging from the Tulsa Opera Chorus, and fundraising events that involve Board, Guild, and additional community volunteers.
