Kevin James as Kevin Gable: the patriarch of the Gable household. As the series started, Kevin, a recently retired cop married to wife Donna, solves family problems with his down-to-earth principles and some help from Donna. After Donna's death between the first two seasons, the widowed Kevin becomes a helicopter parent who goes to work at a security firm with his ex-partner, Vanessa Cellucci. Kevin is a generally good man at heart, although he tends to sometimes get distracted in his goals. He cares deeply about his family and friends, and is willing to do most anything to help them. •
Erinn Hayes as Donna Gable (Season 1): Kevin's wife and the matriarch of the Gable household for the first season, Donna is a school nurse until she quits in the first-season finale (also her last physical appearance in the series). Donna dies before the second season. The episode "The Fantastic Pho" reveals that Kevin and Donna had first met at a bar, and "The Might've Before Christmas" reveals that Vanessa urged Kevin and Donna to get together. •
Taylor Spreitler as Kendra Gable-Witt: The elder Gable daughter, Kendra is a 21-year-old college student (she gets into
Columbia Law School in the first-season finale) who also works as a waitress at Enzo's. She has the most prominent role of the three Gable children in the series. In the pilot, she reveals her engagement to her parents and moves back in with her fiancé Chale. Kendra is the most responsible and dependable of the Gable kids. She also shows a tendency to nag, particularly at Chale's expense. She plans her wedding during the first season and marries Chale in the Season 2 premiere after he faces deportation. Following the death of Donna, Kendra becomes the surrogate matriarch of the family. •
Ryan Cartwright as Chale Witt: Kendra's English fiancé and then her husband. He moves into the Gables' garage with Kendra. Chale is shy and soft-spoken, but very intelligent. Kevin is initially hostile to Chale, but their relationship improves over the course of the series. During Season 1, Chale is unemployed but working on an app that he believes will be a huge success. In the Season 2 premiere, Chale marries Kendra as he faces
deportation. Chale begins working at Enzo's with Kendra in "Plus One Is the Loneliest Number" and is promoted to manager (and temporarily stops working on his app) in "The Kevin Crown Affair". •
Mary-Charles Jones as Sara Marie Gable: the younger Gable daughter, has
anger-management issues and is somewhat a
tomboy, as she excels at and loves sports, watches football and frequently fights. She also has a rebellious streak; she has been suspended, stolen her father's money, created a secret second
Facebook account and snuck off with her boyfriend. Despite her hostility, she does love her family. In the first season, Sara appears mostly in short, cameo roles, but she becomes more prominent in the second season. • James DiGiacomo as Jack Gable: the Gables' 11-year-old
hypochondriac son, is the weakest of the children and somewhat dim-witted. Though he frequently tries to make friends, he finds little success. In the first season, Jack appears mostly in short, cameo roles, but he becomes more prominent in the second season. • Gary Valentine as Kyle Gable: Kevin's older brother, is a firefighter with the
New York City Fire Department of below-average intelligence. Kyle is a bachelor and has a crush on Vanessa (much to her dismay).
