Uncle Jesse Katsopolis – Full House (1987–1995) and Fuller House (2016–2020)
There is no defining John Stamos without the motorcycle-riding, Elvis-obsessed, rock-and-roll uncle who stole America’s heart. As Jesse Katsopolis, Stamos brought an ideal blend of swagger, comic timing, and genuine paternal warmth to the Tanner family household. His signature catchphrase, “Have mercy,” and hit musical moments with his band Jesse and the Rippers remain defining pieces of 1990s pop culture.
Dr. Tony Gates – ER (2005–2009)
Stamos proved his dramatic chops when he joined NBC’s long-running medical drama ER as Dr. Tony Gates. A former Gulf War veteran paramedic turned paramedic-turned-ER resident, Gates was a complex, flirtatious, yet deeply devoted doctor navigating intense trauma and personal turmoil. Stamos brought a grounded intensity to the ensemble cast during the show’s final seasons.
Blackie Parrish – General Hospital (1982–1984)
Before he was a sitcom superstar, an 18-year-old Stamos launched his television career on the iconic daytime soap opera General Hospital. Playing street-smart foster kid Blackie Parrish, Stamos became an overnight teenage heartthrob, earning a Daytime Emmy Award nomination and setting the trajectory for his long career.
Dr. Nicky Angevine – YOU (2018–2019)
Showcasing his ability to embrace darker, morally ambiguous roles, Stamos joined Netflix’s psychological thriller YOU as Dr. Nicky Angevine. Playing an unconventional, weed-smoking therapist who treats Beck (Elizabeth Lail) and unwittingly counsels serial killer Joe Goldberg (Penn Badgley), Stamos brought sharp charisma to a storyline that ultimately takes a dark turn when Joe frames him for murder.
Coach Marvyn Korn – Big Shot (2021–2023)
In Disney+’s sports comedy-drama Big Shot, Stamos took center stage as Marvyn Korn, a temperamental, high-profile college basketball coach who gets ousted from the NCAA and forced to take a job teaching at an all-girls private high school. Stamos delivered a warm, layered performance, charting Korn’s evolution from a rigid perfectionist into a supportive mentor.
Jimmy Martino – Grandfathered (2015–2016)
Leading Fox’s single-camera comedy Grandfathered, Stamos played Jimmy Martino, a suave, perpetual bachelor and successful restaurant owner whose life is turned upside down when he discovers he is not only a father, but also a grandfather. Stamos earned a People’s Choice Award for his winning turn as a man reluctantly discovering the joys of family life.
Dr. Brock Holt – Scream Queens (2016)
Joining Ryan Murphy’s campy horror-comedy anthology series for its second season, Stamos starred as Dr. Brock Holt, a brilliant, secretive head surgeon with a transplanted hand that has a murderous mind of its own. Stamos leaned heavily into the show’s dark satire, matching the fast-paced, absurd comedic tone of the series effortlessly.
Dr. Carl Howell – Glee (2010–2011)
Stamos showcased his genuine musical talents during a memorable guest arc on Glee as Dr. Carl Howell, a charming dentist who dates guidance counselor Emma Pillsbury (Jayma Mays). Performing showstoppers like “Hot Phatie” and leading a dream sequence cover of The Rocky Horror Picture Show‘s “Whatever Happened to Saturday Night?”, Stamos reminded audiences of his stage roots.
