Kevin Ryan

Played by Seamus Dever

character

NYPD Detective Kevin Ryan works alongside Esposito as part of Beckett’s investigative team. He began his career working Narcotics squad but jumped at the opportunity to work Homicide. Ryan is charming, quick on his feet, and has a wealth of obscure knowledge. Always contributing a random fact or some unique piece of insight, he is a focused and invaluable detective. Recently married to the love of his life, Jenny, he is extremely loyal both in his personal and professional life. Though he often pokes fun at his co-workers, Ryan has no problem admitting his own shortcomings. He is a dedicated professional, who often enjoys having Castle around, but will always go above and beyond to bring criminals to justice.

actor

Seamus Dever has played Det. Kevin Ryan for the past six very successful seasons of "Castle." An actor since the age of six, Dever has performed in over 60 plays and musicals in his lifetime. He credits his drama teacher father and history professor mother for their support, balance and encouragement.

Dever is widely recognized to audiences from his breakthrough performances as Dr. Getti on "Army Wives" and Dr. Ian Devlin on ABC's "General Hospital." He recently appeared on "Mad Men" and "Drop Dead Diva," and he still pops up from time to time on repeats of his old guest star roles on all three "CSI" shows, as well as "NCIS," "Charmed," "Cold Case" and "Without a Trace." On the big screen he appeared in "Hollywoodland" and in the independent comedy "Ready or Not." He most recently starred in and produced the Tribeca Film festival short, "Sequestered."

Well known to Los Angeles theatre audiences, Dever portrayed Alex in the LA premiere of "A Clockwork Orange." He received rave reviews and nominations for an Ovation Award, Garland Award and Los Angeles Drama Critics Circle Award. One of the highlights of his LA theatre career was his notable performance in "iWitness" at The Mark Taper Forum. This past summer, he starred in LA Theatre Works' "The Hound of the Baskervilles."

Dever was born in Flint, MI and moved to Bullhead City, AZ when he was six years old. Valedictorian of his high school, he received a bachelor's degree in theatre after only three years at Northern Arizona University. He was accepted into the graduate program at the prestigious Carnegie-Mellon University and The Moscow Art Theatre. He holds master's degrees in acting and is the youngest person to have completed this program. He is also a lifetime member of the renowned Actors Studio.

Dever's wife, Juliana, is known to "Castle" fans as Jenny on the series. They are both proud vegetarians, are active in animal rights and animal rescue causes, and live happily in Los Angeles with their two rescue dogs.
