Early Life and Education
Courtney Healy Henggeler was born in Phillipsburg, New Jersey, and spent her childhood in the Pocono Mountains region of Pennsylvania. Her family relocated to Seaford, New York on Long Island’s South Shore when she turned 14. This move to her parents’ hometown shaped her teenage years and introduced her to performing arts.
Her acting journey began unexpectedly during ninth grade at Seaford High School. Her childhood friend Patti convinced her to audition for the school production of Carousel. She performed an unconventional audition where she pretended to eat an apple while singing about clams, showing early signs of creative risk-taking.
After graduating from Seaford High School, she enrolled at SUNY Fredonia but left after two years. She moved to Los Angeles, California to take professional acting lessons. This bold decision in her early twenties launched her path toward television success.
Career Beginnings
Courtney Henggeler’s professional debut came in 2003 with the horror B-movie The Bog Creatures, where she played Susan Beth. Her television debut followed in 2005 on House, appearing as a server in the episode “DNR”. These initial projects provided foundational experience in front of cameras.
Between 2005 and 2010, she landed guest spots on popular series including Criminal Minds (2008), NCIS (2009), and Roommates (2009). She appeared in small films like The Legacy of Walter Frumm (2005) and Two Dollar Beer (2009). Each role helped her build industry connections while refining her craft.
During this period, she balanced multiple projects including Accidentally on Purpose (2009), Working Class (2011), and Happy Endings (2011). Her willingness to take various guest appearances kept her working steadily. This phase reflects what most actors experience before landing signature roles.
The Big Bang Theory Era
In 2008, Courtney Henggeler landed a guest spot on CBS’s The Big Bang Theory as Missy Cooper. She played the neurotypical twin sister of Jim Parsons’ socially awkward genius Sheldon Cooper. The episode “The Pork Chop Indeterminacy” showcased her comedic timing and chemistry with the cast.
She returned in 2013 and again in 2018 for Sheldon’s wedding in “The Bow Tie Asymmetry”. Despite only three appearances, Missy Cooper resonated enough that Young Sheldon featured the character as a main role. Raegan Revord played the younger version throughout the prequel’s seven-season run from 2017 to 2024.
Reflecting on her experience during a June 2025 appearance on The Official Big Bang Theory Podcast, she admitted feeling disconnected from the show’s massive success. “I realized for all these years, I just felt like a fraud, sort of, because I only did this one episode,” she told host Jessica Radloff (The Official Big Bang Theory Podcast, June 2025). She acknowledged it became “a wonderful thing to be part of and what a wonderful thing to be associated with.”

Building Television Career
Between 2013 and 2018, Courtney Henggeler built steady television presence through recurring roles. She appeared as Claudia on CBS sitcom Mom from 2013 to 2015. She also landed roles in Back in the Game (2013), Royal Pains (2014), and Franklin & Bash (2014).
Her film work included Friends with Benefits (2011) alongside Justin Timberlake and Mila Kunis, plus Hitting the Cycle (2012) and Kristin’s Christmas Past (2013). She appeared in Faking It (2014), The Mysteries of Laura (2014), and Stitchers (2015). These projects maintained her industry visibility.
In 2018, she appeared in Jane the Virgin as Satchet and Fuller House as Renee. She also worked on Nobody’s Fool (2018) and Hulu’s horror anthology Into the Dark in the “Pilgrim” episode. Each project added experience while she waited for a career-defining opportunity.
The Cobra Kai Breakthrough
Courtney Henggeler’s career transformed in 2018 when cast as Amanda LaRusso in Netflix’s Cobra Kai. The show continued the beloved Karate Kid film franchise from the 1980s. As wife of protagonist Daniel LaRusso (Ralph Macchio), Amanda initially served as the voice of reason amid resurgent karate rivalries.
What distinguished her performance was refusing to let Amanda remain peripheral. Over six seasons from 2018 to 2025, she advocated for deeper character development. By Season 4, Amanda had evolved from skeptical outsider to active participant in the Valley’s karate conflicts.
Her unexpected mentorship of Tory Nichols (Peyton List), her daughter’s rival, became compelling. In a 2022 interview with The Hollywood Reporter, she discussed this evolution: “I asked to know more about her, which they incorporated with Tory really beautifully. She sees so much of herself in Tory” (The Hollywood Reporter, 2022). This backstory deepened Amanda’s character beyond typical wife roles.
The show became one of Netflix’s most-watched series globally. It introduced the Karate Kid franchise to new generations while satisfying original 1980s fans. She compared the passionate fanbase to Big Bang Theory fans but noted Cobra Kai enthusiasts brought energy “to a new level.”
Personal Life
In October 2015, Courtney Henggeler married Ross Kohn, beginning a partnership that has lasted through her biggest career successes. The couple married on October 10, 2015. Their relationship remained relatively private despite her growing fame.
They welcomed son Oscar Noah Kohn on January 25, 2017. She shared humorous updates with fans, including a first birthday post mentioning she was eating her “third fudgecicle” when labor began. Their daughter Georgie Healy Kohn arrived on March 1, 2019.
She announced her second pregnancy to PEOPLE magazine in January 2019 with characteristic humor. “We’re mostly excited and only partially terrified to announce that we’re expecting Baby Kohn: Part Deux” (PEOPLE, January 2019). She filmed Cobra Kai Season 2 while pregnant, using compression garments to conceal her condition on camera.
Net Worth
According to Celebrity Net Worth Courtney Henggeler’s net worth stands at approximately $4 million as of 2025. Her primary income source includes the starring role in Cobra Kai across six seasons. The show’s success on Netflix provided steady compensation and increased her streaming-era visibility.
Residuals from The Big Bang Theory, one of television’s highest-earning syndicated shows, contribute ongoing payments. Despite only three appearances, the show’s global syndication generates continuous income. Her recurring role on CBS’s Mom from 2013 to 2015 also provides residual payments.
Film appearances in Friends with Benefits (2011), Nobody’s Fool (2018), and The Boys in the Boat (2023) added to earnings. Over her 22-year career, she balanced television with film projects. This approach built financial security before her 2025 retirement.
Retirement from Acting
In March 2025, Courtney Henggeler announced retirement from acting after more than two decades. She called her agents and told them she was “tapping out” of the business. The decision surprised fans who loved her work on Cobra Kai and The Big Bang Theory.
In a candid Substack post, she explained frustrations with industry demands rather than acting itself. “Not because of the acting itself. But because of the gauntlet I had to run to reach the acting.” When asked about her plans, she replied: “I want to be the machine.”
She relocated to Connecticut, purchasing what she calls “the house that Cobra Kai built.” Speaking on The Official Big Bang Theory Podcast in June 2025, she described withdrawing from social media: “I don’t mess with social media anymore. I think I’m a happier person because of it.” Her retirement at 46 reflects performers prioritizing personal well-being over sustained fame.
Legacy and Impact
Courtney Henggeler’s career shows that Hollywood success doesn’t require continuous leading roles. Through memorable performances in two culturally significant series, she created characters that became part of television history. Her Missy Cooper remains beloved despite minimal screen time, while Amanda LaRusso challenged typical supporting wife portrayals.
Fans recognize her as either “Sheldon’s sister or Daniel LaRusso’s wife,” connections to iconic shows representing her cultural contribution. Her work on Cobra Kai showcased how streaming platforms like Netflix could revive classic franchises. She advocated for deeper female characters in action-oriented programming.
Her decision to step away on her own terms offers alternative narratives to conventional entertainment trajectories. She prioritized personal fulfillment over industry expectations, embracing quieter life in Connecticut. Her legacy includes performances and advocacy for complex female representation.
