Meet the Grey’s Anatomy season 13 cast right here:

#1 Meredith Grey (Ellen Pompeo): The protagonist of Grey’s Anatomy returns as a single mother, juggling her work as a doctor at the Grey Sloan Memorial Hospital, and raising her two young children. After the death of her husband, Derek Shepherd (Patrick Dempsey), Meredith eventually moves on with a new doctor, Nathan Riggs (Martin Henderson) in the season 12 finale.

#2 Alex Karev (Justin Chambers): One of the only remaining original Grey’s Anatomy cast members, Alex lands himself in trouble with the law, after beating up a colleague named Andrew DeLuca (Giacomo Gionniotti) within an inch of his life. Coming from the wrong side of the tracks, he is impulsive and aggressive in nature and is in a relationship with Jo Wilson (Camilla Luddington).

#3 Miranda Bailey (Chandra Wilson): Bailey is a beloved member of the Grey’s Anatomy cast, and reprises her role as the tough-talking doctor with a heart of gold. Being an experienced surgeon and a mother, she often doles out blunt advice to her colleagues and solves their personal and professional problems.

#4 Arizona Robbins (Jessica Capshaw): The quirky pediatric surgeon is a ray of sunshine as she roller skates around Grey Sloan Memorial Hospital, spreading joy and happiness everywhere she goes. She was married to her colleague, Callie (Sara Ramirez), and has a daughter with her. Unfortunately, the happy couple got a divorce last season, after Arizona lost one leg in an accident and subsequently cheated on her wife.

#5 Richard Webber (James Pickens Jr.): Previously the Chief of the Hospital, Webber is a father-figure to the residents and attending doctors and is known for his gentle and soft-spoken ways. He lends a friendly ear to the younger physicians and helps resolve their disputes. He is married to a fellow doctor, Catherine Avery (Debbie Allen).

#6 Owen Hunt (Kevin McKidd): A former U.S. Army trauma surgeon, Owen served in the Iraq war and initially faced problems adjusting to regular civilian life. He was earlier married to a former Grey’s Anatomy cast member, Cristina Yang (Sandra Oh), but wed Derek’s sister, Amelia Shepherd (Caterina Scorsone) in the season 12 finale of the critically-acclaimed drama.

Grey’s Anatomy is known for its diverse ensemble cast, thanks to its talented writer-producer, Shonda Rhimes. The large and blended Grey’s Anatomy season 13 cast also includes Sarah Drew (April Kepner), Jesse Williams (Jackson Avery), Caterina Scorsone (Amelia Shepherd), Jerrika Hinton (Stephanie Edwards), Kelly McCreary (Maggie Pierce), Martin Henderson (Nathan Riggs) and Jo Wilson (Camilla Luddington) among many others.

Grey’s Anatomy fans were heartbroken to see main cast member, Callie Torres (Sara Ramirez) exit the show in the season 12 finale, raising questions about the fate of the show, especially after so many of its original cast members have left. This came after series regular, Patrick Dempsey (who played the role of Derek Shepherd) was written off in Grey’s Anatomy season 11, much to the dismay of viewers.
