Cara Buono (born March 1, 1971—some sources list 1974) is an American stage, film, and television actress whose career has moved fluidly between New York theater, independent cinema, and high-profile TV dramas. She’s best known to wide audiences as Karen Wheeler on Netflix’s Stranger Things and for her Emmy-nominated turn as Dr. Faye Miller on AMC’s Mad Men.
Early life and training
Raised in the Bronx in a working-class Italian-American family, Buono grew up with the city’s particular mix of toughness and improvisation. She was drawn to performance early and made a professional-level stage debut as a child, appearing at age 12 in Harvey Fierstein’s play Spookhouse, a formative experience that set her on a theatrical track.
Buono attended Fiorello H. LaGuardia High School of Music & Art and Performing Arts, the famed New York public arts conservatory that has incubated generations of actors. She then enrolled at Columbia University, where she accelerated through a double major in English and political science, graduating in three years. The combination is telling: craft on one side, rigorous reading and argument on the other. It helps explain why Buono’s performances often feel intellectually “tuned”—not showy, but specific, lived-in, and alert to subtext.
Stage roots
Before Hollywood really noticed her, Buono was a theater actor. In the 1990s she built credibility in New York, working both on Broadway and off-Broadway, where she learned the kind of discipline that doesn’t always show up in a résumé but shows up on screen: how to play a scene economically every night, how to keep a character alive even when you’re not speaking, how to take an audience’s temperature and respond without breaking the frame.
These years also placed her in the city’s indie-theater ecosystem, where actors are expected to carry emotional weight without cinematic close-ups or editing tricks. That background is a big part of why Buono can slip into supporting roles and make them feel like full biographies rather than “types.”
Breakthrough in film and the indie lane
Buono’s film career began in the early 1990s with roles in features such as Waterland (1992). Over the next decade she became a familiar presence in independent cinema, often choosing projects that were character-driven rather than prestige-branded. She co-produced and starred in Two Ninas (1999), signaling early that she wasn’t just an actor for hire but someone invested in shaping stories.
While she has appeared in studio films—Hulk (2003) among them—Buono’s indie work is where you see her taste most clearly: smart, slightly off-center narratives where a quiet performance can anchor the emotional reality. That taste also kept her nimble as the industry shifted; she never had to “reinvent” herself because she never stopped working in multiple lanes.
Television ascendancy
If film gave Buono variety, television gave her scale. She took recurring and guest roles across major dramas and procedurals, including multiple appearances in the Law & Order universe over the years. Those shows are a proving ground for precision: you have limited screen time and still need a clear, understood inner life. Buono consistently delivered that.
Two TV roles, in particular, defined her public profile:
-
Kelli Moltisanti in The Sopranos
Buono entered The Sopranos late, playing Kelli, Christopher Moltisanti’s wife. Dropping into a world as richly textured as that series is hard; characters can feel like accessories if they don’t land immediately. Buono avoided that trap by playing Kelli with grounded normalcy—someone attracted to the glamour of mob proximity, yes, but also someone trying to build an ordinary domestic future inside an extraordinary moral mess. The performance is restrained, which is exactly why it works. -
Dr. Faye Miller in Mad Men
Her portrayal of Faye Miller—a psychologist and consumer-research consultant who becomes romantically involved with Don Draper—earned Buono a Primetime Emmy nomination for Outstanding Guest Actress in a Drama Series. Faye is not a typical love interest. She’s intelligent, observant, and professionally trained to read people who don’t want to be read. Buono plays her as a woman who matches Don’s intellect but not his self-deception, and that difference is what makes their arc so quietly brutal. Faye sees Don clearly; Don can’t stand being seen. Buono’s calm, analytical warmth gives the character real gravity and makes her eventual sidelining feel like a loss—not just for Don, but for the show’s moral balance.
Mainstream visibility: Stranger Things
Buono’s widest audience came with Stranger Things, where she plays Karen Wheeler, the mother of Mike and Nancy. At first glance Karen might read as a period-appropriate suburban mom, but Buono shades her with restlessness and unspoken intelligence. You sense a whole interior life humming beneath the 1980s wallpaper: a woman who loves her family and still wonders if that’s all there is.
That subtle layering matters in an ensemble show dominated by kids and monsters. Buono helps the adult world feel real, not just functional. As the series progresses, Karen becomes a kind of emotional barometer for the cost of all this chaos—especially in the way Buono plays worry as something practical and bodily, not melodramatic.
Other notable screen work
Across film and TV, Buono has built a portfolio that’s less about single stardom moments and more about steady, high-quality presence: roles in Let Me In (2010), A Good Marriage (2014), and later indie features all show her ability to calibrate to tone—horror, drama, satire—without ever feeling like she’s “trying to fit.”
Personal life
Buono is married to entrepreneur Peter Thum; they wed in 2009 and have a daughter. She has kept her private life relatively low-profile, which aligns with her public persona: not elusive, just focused on work rather than spectacle.
Why her career lasts
Buono’s longevity isn’t an accident. She’s a classic “actor’s actor”: trained early, theater-hardened, comfortable in lead or supporting space, and unusually good at suggesting history without announcing it. She also chose roles that didn’t box her into one brand. By moving between stage, indie film, and television—and by treating each as serious craft—she built a career that can adapt to whatever the medium wants next.
