Thanks for replies,but i dont think i can improve in acting because i'm deaf and it would be hard to find a job in Hollywood and against hearing talented actors.I must find something else.
There is one in California.
Deaf West Theatre Company is a North Hollywood, California-based cultural institution serving as a model for deaf theatre worldwide. Founded in 1991, by Ed Waterstreet, it is noted for being the first professional resident Sign Language Theatre in the western half of the United States. Deaf West Theatre productions, actors and directors have won more than 80 theatre awards for artistic merit.
You can work as an actor if you have college degree in acting. It is up to you.
Then there is another Deaf theater in Connecticut, USA.
The National Theatre of the Deaf (NTD) is the oldest theatre company in the United States that has continually gone on tours and produced original works. The company has visited each of the 50 states in close to 80 national tours, as well as many countries in over 30 international tours. It was founded in 1967 after psychologist Dr. Edna Simon Levine, set designer David Hays, and Broadway's director Arthur Penn and actress Anne Bancroft of The Miracle Worker began planning and fundraising in the 1950s. In 1968, the Little Theatre of the Deaf was founded to produce shows for a younger-aged audience. The Little Theatre of the Deaf is also still producing and touring today. Productions combine the use of American Sign Language with the spoken word, in accordance with the theatre's mission statement to educate the general public about Deaf art and link Deaf and hearing communities. In 1994, the National and Worldwide Deaf Theatre Conference had its first meeting, in which global Deaf playwrights and actors gathered to hold discussions, critiques, and celebrations of Deaf theatre. The precedence and support of the National Theatre of the Deaf is considered instrumental in the founding and collaboration of a Deaf theatre community worldwide. The National Theatre of the Deaf has won several awards, including the Tony Award for Theatrical Excellence. Ex-NTD actress Phyllis Frelich won the 1980 Best Actress Tony Award for Children of a Lesser God produced by The Mark Taper Forum in Los Angeles. Linda Bove, a regular on the television series Sesame Street, also acted with NTD. Other famous actors who have worked with NTD include NTD co-founder Bernard Bragg, Colleen Dewhurst, Sir Michael Redgrave, Chita Rivera, Jason Robards and Meryl Streep.[3] Today, the Theatre is located on the campus of the American School of the Deaf in West Hartford, Connecticut. The theatre still goes on tour, produces and adapts stage works, and is expanding into a few teleplay features on public television to continue to create new opportunities and audiences for Deaf theater.
I don't know of any other Deaf theatres in USA and Not sure of Canada. That is all I know of those two theatres. You can go to Gallaudet to learn how to become Deaf actor. If you don't want to be in the Deaf theatre but would like to be involve in the hearing theatre, then that would be hard for you if you are deaf or hard of hearing. I hope you can accomplish your achievement on becoming an actor if you are really good at it. Good luck.
