Wendi McLendon - Covey as Beverly Goldberg (née Solomon), the overprotective matriarch of the Goldbergs. She frequently injects herself into her children 's lives, often to their embarrassment, and is supremely confident in their abilities. Sean Giambrone as Adam Fredrick Goldberg, the pop - culture obsessed youngest child of the Goldbergs. Smart and geeky, he often films his family 's activities on a VHS camcorder. He often ends up having to use his middle initial to distinguish himself from another Adam Goldberg who attends the same school and is also an aspiring filmmaker. Patton Oswalt voices the adult Adam Goldberg, who narrates the show from the present day. Jeff Garlin as Murray Goldberg, the gruff, somewhat asocial patriarch of the Goldbergs. Unlike Beverly, he is realistic about his children 's abilities and believes she smothers them too much. Despite his apathetic tendencies at home, he values hard work and has held various full time positions since his teenage years. Though he does not always show affection for his children, calling them morons when they make mistakes or behave in silly ways, he truly cares about them and wants them to learn how to fend for themselves. He runs his father - in - law 's furniture business, loves sports, and is often seen lounging in front of his TV in his white briefs. Troy Gentile as Barry Norman Goldberg, the overconfident, slightly dim - witted middle child of the Goldbergs. Though seemingly untalented in every way (except in ice hockey and wrestling, at which he excels), he remains highly self - assured while trying to become popular in high school. He is determined to dominate everything he does, including sports; loves rap music; and is the leader of a crew called the Jenkintown Posse (abbreviated JTP, which fellow members repeat whenever the initials are spoken). Hayley Orrantia as Erica Dorothy Goldberg, the somewhat bad - tempered oldest child of the Goldbergs. Smart and musically gifted but rebellious, she is popular in school and dominant over her younger brothers. As of the fifth season, Erica has left for college at DC. School of the Arts. "Erica '' is based on Adam 's real - life brother, Eric Goldberg. George Segal as Albert "Pops '' Solomon, Beverly 's laid - back widower father. Though an elderly man with a number of comic eccentricities, he acts much younger than his age and often gives sage advice to his grandchildren. Adam considers him his best friend. He once owned a successful furniture store called Ottoman Empire that allowed him to retire comfortably, and he now lets his son - in - law Murray run the business. AJ Michalka as Lainey Lewis (Season 3 -- 4; recurring 1 -- 2, 5 - present), Erica 's best friend and one of the most popular girls at school, whom Barry has had a lifelong crush on. To the surprise of many, Lainey kisses Barry at a party in the first - season finale, the two slowly grow closer together in season two, and eventually become an unlikely couple. Following the fourth season, she has gone to attend fashion school in Savannah, Georgia and ended her relationship with Barry. In season 5, she returns to Jenkintown after dropping out along with Erica to start a band. In the final seconds of the season finale she and Barry agree to wed. Sam Lerner as ' Madman ' Geoff Schwartz (Season 5 - present; recurring 2 - 4), one of Barry 's best friends. The nickname "Madman '' is a form of ironic humor, given how well - behaved the character is, especially compared to Barry. He is infatuated with Erica and makes many futile attempts to win her affections. At the end of the third season, he begins dating Evelyn Silver just as Erica realizes she reciprocates Geoff 's feelings. He later breaks up with Evey to be with Erica.
