Veteran talent agent Gabrielle Krengel, partner at Domain Talent agency, died Monday, August 3. She was 49. Krengel, whose clients included Jane Lynch, had been diagnosed with cancer in late 2014, for which she underwent treatment. In July, she had fallen ill from pulmonary embolisms, complications from which ultimately caused her death.

Krengel’s passing shocked many in the talent world as very few had been aware that she was sick. “She didn’t tell anyone, so no one had the chance to tell her how loved she was…or say goodbye. I’m so sad,” one casting director said. Krengel had kept her health struggle private even to those she was closest to in the business, putting her clients, colleagues and friends in the industry first, a close associate said.

Client Emily Rose posted her reaction on Twitter this morning.

Krengel, who was universally loved in the community, had a number of long-time clients, including Lynch, who had been with her for well over a decade.

Born in New York City and raised in Los Angeles, Krengel, an UCLA graduate, started her career at Abrams Artist Agency working for Nina Pakula whom she followed when Pakula formed her own agency, Pakula/King. Krengel became an agent there and later joined Susan Smith & Associates where she worked with famous industry veteran Susan Smith. Upon the closing of that agency, Krengel went to Metropolitan Talent Agency where she worked with her Domain co-founders Melisa Spamer and Joe Vance. The trio left in 2005 to start Domain Talent, a boutique agency representing actors in TV, film and theater.

“She stood five foot two and “a half” as she reminded people. But she was a giant,”close friend and manager Theodore Gekis said. Added casting director Felicia Fasano, also an old friend of Krengel’s, on Twitter, “She was one of a kind and a class act in this town. She will be missed.”
