Early life Sean Strickland grew up in Corona, California, in a household with a physically and mentally abusive father. He has one brother. During Strickland’s early childhood, he attacked his father with a guitar in an attempt to defend his mother out of fear he might kill her. Strickland fled from his house and contacted his local law enforcement leading to his father being briefly arrested. However, the next day his father was released from jail as his mother paid for his bail.
In Strickland’s adolescence, he developed a close relationship with his grandfather, who exposed him to neo-Nazi ideology. In ninth grade Strickland was expelled from school for perpetrating a hate crime; afterwards, his mother brought him to an MMA gym to help him cope with his problems. Strickland stated, "Then I started training and the moment I started training I was like...I don't hate anybody. Everyone's cool. Then a lot of people who helped me out in my life, they weren't white."
At the age of 18, Strickland had another violent altercation with his father again resulting in police involvement. However, no charges were pressed. Following this, Strickland and his mother moved out of his father’s house. During a 2024 episode on the This Past Weekend podcast, he revealed that his father had died of cancer following a long-term drug addiction.

Fighting style Fighting in a notably upright, orthodox stance, Strickland is distinguished for his defensive striking. In the UFC’s official Significant Strike Defense statistic, he has a 60.9% defense rate—the highest among active fighters in the middleweight division.
UFC commentator Joe Rogan stated regarding Strickland’s defense, “He spars more than anybody in the UFC and they put a mouthpiece that measures how many times you get hit. He gets hit less than anyone [and] he’s got phenomenal defense.”
Central to Strickland’s defensive approach is his incorporation of the Philly Shell guard, referring to the positioning of the lead hand on the lower torso and the back hand closer to the side of the face. This allows Strickland to fight defensively by using the shoulder roll as well as parrying strikes and actively checking kicks.
Offensively, Strickland prefers to utilize his boxing within his fights. Strickland applies pressure by constantly walking forwards and forcing his opponents into boxing range, in which he then applies jabs often in volume and followed by a right cross.
Strickland generally applies his wrestling defensively to great effect, with a high takedown defense statistic of 68%. Strickland may pursue top position to engage in powerful ground and pound.

Strickland was previously an avid supporter of Donald Trump; however, in February 2025, Strickland questioned some of Trump's pro-Israel views and began wondering if it was a "mistake" re-electing him.
