With every new episode of The Good Doctor comes a whole cast of new characters, whether they’re patients being treated by the St. Bonaventure staff or people who pop up in the doctors’ lives outside of work. This constant stream of new additions can often leave viewers scratching their heads and asking themselves, “Where have I seen this actor before?!” But before you go down a rabbit hole of IMDB pages searching for the answers, look no further: We’ve got a complete list of The Good Doctor’s season 3 guest stars and new cast members right here.
Bentley Green (Episode 19)
At only 19, Bentley Green has made a name for himself as an actor, rapper, and social media personality. Before his appearance on The Good Doctor as Casey Taylor — a rebellious teenager — he starred on Grey’s Anatomy and Snowfall.
Avery Konrad (Episode 19)
Avery Konrad’s character, Tamara Krantz, stood out from the rest because her medical emergency was unrelated to the earthquake. The actress collaborated with The Good Doctor cast for the thrilling two-part season finale.
John Patrick Amedori (Episode 17)
Actor John Patrick Amedori first appeared as Dash Snyder on season 2 of The Good Doctor, when his wife (and Dr. Claire Browne’s college roommate) was diagnosed with terminal ovarian cancer. Now he’s returned in season 3 as a widower and a seeming love interest for Claire — but he’s also starred in Dear White People, among other shows.
Ever Carradine (Episode 17)
After you watch Ever Carradine as patient Alice Gottfried on The Good Doctor, queue up The Handmaid’s Tale on Hulu to catch her as Naomi, Commander Warren Putnam’s wife.
David Cubitt (Episode 17)
It’s possible you also recognized Alice’s husband, Owen, who was played by David Cubitt — he’s probably most known for his role on NBC/CBS’s Medium, but he’s also appeared in such shows as Altered Carbon and Bates Motel.
Harold Perrineau (Episode 17)
Harold Perrineau tugged at our heartstrings as patient Wes Keller on The Good Doctor. But before that, you probably saw him in one of his many other projects, which have ranged from Lost to 1996’s Romeo and Juliet movie.
Ricky He (Episode 17)
When Dr. Alex Park’s son, Kellan, appeared in season 3 of The Good Doctor, he was played by actor Ricky He, who had previously played Kellan in season 2. This isn’t the only hit ABC show Ricky’s played a recurring role in, however — you can also see him as Don in A Million Little Things.
Cameron Gellman (Episode 16)
Not only did Cameron Gellman play two different characters (who just happened to be stuck in the same body) on The Good Doctor, but he’s also starred in Paramount Network’s TV series version of Heathers and The CW’s upcoming DC Comics show Stargirl.
Brittany Willacy (Episode 15)
If you’ve ever watched The CW’s hit teen drama Riverdale, you might recognize actor Brittany Willacy. She’s played Laura on several episodes of the show, but most recently appeared as patient Fran — a firefighter who was bitten by a dog — on The Good Doctor.
Neil Webb (Episode 15)
Remember Lea’s date, Teddy, at the karaoke bar in episode 15? His real name is Neil Webb, and he’s also appeared in such shows as A Million Little Things and The Flash.
Chelsea Alden (Episode 14)
On The Good Doctor season 3, Chelsea Alden played an influencer. In real life, she has a large social media following too — probably because she’s acted in all sorts of movies and TV shows, including Netflix’s 13 Reasons Why.
Cristina Rosato (Episode 14)
Before guest-starring as patient Ann in The Good Doctor season 3, Canadian actor Cristina Rosato starred in the CBC’s show 21 Thunder.
