Trying to keep a running list of all the theater companies in Las Vegas is a Sisyphean task. In addition to larger organizations that have shown great stability, smaller companies pop up and drop off at a frenetic pace. This is only a partial list, curated based on history of productions as well as upcoming work.

Asylum Theatre Artistic Director Sarah O’Connell has this company focused on new work from up-and-coming playwrights, including a series of staged readings of works-in-progress from across the country. The next Asylum production will be a staged reading of Reckoning, February 8 at the Onyx. asylumtheatre.org

Cockroach Theatre The home company at Art Square Theatre produces a mix of classics (Death of a Salesman, No Exit) and newer works (Nurture and the upcoming Mr. Burns, a Post-Electric Play), all with a feisty, combative edge. Their latest production, Bug, by Tracy Letts, opens January 16. cockroachtheatre.com

Las Vegas Little Theatre One of the twin pillars of Las Vegas theater life, LVLT produces mainstream theatrical fare with excellent production values in its larger mainstage (think Neil Simon, Christopher Durang) while its Fischer Studio Black Box offers smaller productions with more teeth. The LVLT Studio is an intimate venue that nomadic companies often rent to show their own material. Neil Simon’s Rumors is currently playing on the mainstage, while the tart Hollywood satire Little Dog Laughed opens in the Black Box January 16. lvlt.org

Off-Strip Productions The in-house producing arm of the Onyx has taken a turn from musicals towards a more irreverent, comedic slate. The Get is a weekly comedy show, and Four Dogs and a Bone, another biting satire of the greed of Hollywood, opens January 23. onyxtheatre.com

Poor Richard’s Players A serious theater company with a strong comedic backbone, Poor Richard’s Players will host a very literary 2015, with productions including Of Mice and Men, Frankenstein and Moby Dick—Rehearsed. poorrichardsplayers.com

A Public Fit This company started with a group of readings in houses, graduated to monthly staged public readings Downtown, and produced their first full production last fall at Art Square. They rally around the idea of paying their artists professional wages and creating work that allows their talented group to flex their artistic muscles. Their next reading, title to be determined, takes place January 30 at the Scullery. apublicfit.org

Signature Productions This longtime Summerlin organization produces family-friendly musicals with large casts, loads of dancing and lavish production values. It will put on Mary Poppins this spring. signatureproductions.net

Sin City Opera “Yesterday’s opera today” is the slogan, and it’s delivered by a talented team and a slate that mixes the serious with the frothy. The company will present Trouble in Tahiti at the Winchester Theatre in March. sincityopera.com

Super Summer Theatre The gold-standard of Las Vegas theatres. This 40-year-old institution offers quality, family-friendly musicals and comedies outdoors at Spring Mountain Ranch each summer and has even opened a rehearsal studio closer to town that offers classes for anyone interested in stretching their artistic side. Chitty Chitty Bang Bang is the first musical this year in June. supersummertheatre.org

Table 8 Productions Focused on the funky and experiential, Table 8 produces shows that seek to expand what the audience can expect from a theatrical night out, while exploring the darker side of humanity. Up next is Motel, a devised piece examining the seedy sexual peccadilloes of a cross-section of Las Vegas inhabitants. table8lv.com
