Telly Leung was born and raised in New York City. He grew up in a traditional Chinese home in Bay Ridge, Brooklyn. He is a proud alumni of New York's prestigious math & science specialized high school, Stuyvesant High School. After Stuyvesant, Telly was admitted to Carnegie Mellon University's School of Drama (CMU), where he received most of his formal training in acting, singing, and dance.

It was also at CMU that Telly met fellow CMU-alum and KINKY BOOTS Tony-Award Winner, Billy Porter, who returned to his alma mater to direct the main stage production of Sondheim's COMPANY. After casting Telly as Bobby in "Company", Porter made a phone call to his colleagues who were involved in the upcoming Broadway revival of FLOWER DRUM SONG and landed Telly an audition. In the fall of 2002, Telly made his Broadway debut in the revival of 'Flower Drum Song", starring Lea Salonga, as a member of the ensemble and an understudy for Wang Ta.

After playing Bobby in Sondheim's COMPANY in college, Telly would later get the opportunity to work with the legendary Stephen Sondheim in Roundabout's Broadway revival of PACIFIC OVERTURES in 2005. After PACIFIC OVERTURES, Telly originated the role of Boq in the Chicago company of WICKED, collaborating with fellow CMU-alum, Stephen Schwartz. Other Broadway credits include the final company of RENT - where he also got to make his film debut in Radical Media / Sony's RENT: FILMED LIVE ON BROADWAY, which is available on DVD and Blue Ray. After RENT ended its Broadway run, Telly went on an international tour with original RENT stars Adam Pascal and Anthony Rapp in RENT: THE BROADWAY TOUR. He would later reprise the role of Angel in RENT at the Hollywood Bowl, directed by Neil Patrick Harris and starring Vanessa Hudgens, Aaron Tveit, Skylar Astin, & Wayne Brady. In 2011, Telly would get another opportunity to collaborate with composer Stephen Schwartz in the Broadway revival of GODSPELL at the Circle in the Square Theater.

Telly was involved in the development of Broadway's ALLEGIANCE, creating the role of "Sammy" alongside Lea Salonga (MISS SAIGON) and George Takei (STAR TREK). ALLEGIANCE is the story of one Japanese-American family's struggles and triumphs during the Japanese Internment of World War II. The musical made its sold-out world premiere at the Old Globe Theater in San Diego in 2012 and premiered on Broadway in the Fall of 2015. He received critical acclaim for his "star turn" (NBC-NY) as Sammy, performed with "breakout power" (Newsday), with Rex Reed of the NY Observer praising his portrayal of Sammy as "beautifully played and powerfully sung by handsome and awesomely talented Telly Leung."

Telly has performed live all over the world. Notable venues include Carnegie Hall, the Kennedy Center, the Hollywood Bowl, the Baltimore Symphony, the St. Louis MUNY, The Shakespeare Theater (DC), Pittsburgh CLO, Paper Mill Playhouse, Dallas Theater Center, Philadelphia Theater Company, Sacramento Music Circus, the Old Globe, Fords Theater, North Carolina Theater, Four Seasons Theater, North Shore Music Theater, The Coterie in Los Angeles, The Magic Castle, NYC's Feinstein's / 54 Below, Birdland Jazz Club, and London's Hippodrome.

Telly has appeared on television in GLEE (as Wes of the Dalton Academy Warblers), ODD MOM OUT (Bravo), DEADBEAT (on Hulu), LAW AND ORDER: CRIMINAL INTENT and played Kevin in the pilot of ABC's performing arts drama, LIMELIGHT.

He took an active role in producing his own debut album, {i'll cover you}, as well as his London debut concert in collaboration with Speckulation Entertainment and Marathon Productions. His producing credits include GRIND (a musical short film, starring Anthony Rapp) and BROADWAY @ LEARNING (a concert starring Broadway stars Adam Pascal, Eden Espinosa, and Marcus Paul James).

Telly passionately believes in "paying it forward" and giving back to the next generation of theater artists and performers. Besides being heavily featured as a performance coach for the Jimmy awards on PBS' BROADWAY OR BUST, he can also be frequently seen teaching as a guest instructor in master classes all over the country. In 2013, he was selected as the Tam & Young Arts Chair at Iolani High School in Honolulu and spent a week teaching and performing alongside the students and faculty. He continues to teach young performers as part of a team of coaches at MTCA (Music Theater College Auditions) that helps high school students gain admission into the competitive university training programs.
