Max Adler (born January 17, 1986) is an American actor, known for his role as Dave Karofsky on the television series Glee and Tank on the television series Switched at Birth.
Adler was born to a Jewish family in Queens, New York, the eldest son of Lisa (nėe Kobrin) and Doug Adler. A year after Adler was born, his family relocated to Fountain Hills, Arizona, then to Scottsdale, Arizona. Adler attended Horizon High School, where he was a First Chair All-State show choir member. After graduating, he moved to Los Angeles to pursue a career in acting. Adler has a younger brother named Jake, born in 1992.
After various roles in a number of productions, Adler was cast in a minor recurring role in the Fox television series Glee as school jock and bully Dave Karofsky. Glee creator Ryan Murphy was impressed with his acting and wanted to write more with him. In the November 2010 episode "Never Been Kissed", written to tackle the issue of LGBT youth bullying, Karofsky is revealed to be a closeted gay teen. Adler had previously questioned his character's motivations, but was surprised by the scene in which Karofsky kisses the object of his bullying, openly gay student Kurt Hummel (Chris Colfer). He received a positive response via the social networking websites Twitter, Tumblr and Facebook, and commented that he was "glad to represent such a large group of people". He expanded on this, saying, "I've gotten so many messages from people all around the world these last couple of days thanking me because either they are Karofsky, they were Karofsky or they know a Karofsky." The character eventually gives up his bullying and makes his peace with Kurt, but he remains closeted. Adler has been praised for his performance in episode 3x14, "On My Way", during which, after his character is outed, he attempts suicide.
