The HB Studio (Herbert Berghof Studio) is a non-profit 501(c)(3) organization offering professional training in the performing arts through classes, workshops, free lectures, Theater Productions, theater rentals, a Theater Artist Residency program, as well as full time study through their International Student Program and Uta Hagen Institute. 
Located in Greenwich Village, New York City, HB Studio offers training and development to aspiring and professional artists in a variety of areas, including acting, directing, playwriting, musical theatre, movement and the body, dialect study (speech and voice), scene study analysis, screenwriting and classes for young people. Select classes require an audition for admission.
In 1948, Uta Hagen joined the Studio as Berghof's artistic partner, and the two wed ten years later. Her master classes led to the writing of her books Respect for Acting and A Challenge for the Actor.
In 2010, HB Studio founded the Uta Hagen Institute, which offers full-time immersion in the practical approach to acting craft that characterized Uta Hagen's master classes and classic acting texts. Its two key programs, The Hagen Summer Intensive and The Hagen Core Training, are highly structured, integrated courses for students with serious professional and artistic intent.
