Sadie Sink (born April 16, 2002) is an American actress. She portrays Max in Netflix’s Stranger Things and has also appeared in Blue Bloods and The Americans. Sink has also worked on Broadway, with credits including Annie and The Audience.
Sink was born in Brenham, Texas. She has three older brothers and a younger sister.
Due to her obsession with recreating Disney’s High School Musical with her brother, Mitchell, when she was seven years old, her mother decided to send her off to acting classes in a community theatre, in nearby Houston. In turn, it led to a Broadway audition and a role in the 2012 revival of Annie. She had to prepare herself for the role by taking dance lessons and doing vocal training. She was initially the standby for all the orphans, until the original lead left, when she began alternating the title role for a few months, then closing the show as Duffy and understudy to Annie.
