John Karalis is a 20-year veteran of Celtics coverage and was nominated for NSMA's Massachusetts Sportswriter of the Year in 2019. He is the host of the Locked On Celtics podcast and has written two books about the Celtics.

John was born and raised in Pawtucket, RI. He graduated from Shea High School in Pawtucket, where he played football, soccer, baseball, and basketball and was captain of the baseball and basketball teams.

John graduated from Emerson College in Boston with a Bachelor of Science degree in Broadcast Journalism and was a member of their Gold Key Honor Society. He was a four-year starter and two-year captain of the Men’s Basketball team, and remains one of the school's top all-time scorers, and Emerson's all-time leading rebounder. He is also the first Emerson College player to play professional basketball (Greece).

John started his career in television, producing and creating shows since 1997. He spent nine years at WBZ, launching two different news and lifestyle shows before ascending to Executive Producer and Managing Editor. He then went to New York, where he was a producer and reporter until 2018.

John is one of Boston’s original Celtics bloggers, creating RedsArmy.com in 2006. In 2018, John joined the Celtics beat full-time for MassLive.com and then went to Boston Sports Journal in 2021, where he covered the Celtics for five years. He has hosted the Locked On Celtics podcast since 2016, and it currently ranks as the #1 Boston Celtics podcast on iTunes and Spotify rankings. He is also one of the co-hosts of the Locked on NBA podcast.
