Seamus Dever

With the encouragement of his family, inclusive of drama teacher father, it's no wonder that Seamus Dever endeavored to pursue a career in acting. His current success as star of ABC's critical and audience favorite "Castle" is further testament to his talent. As Homicide Detective Kevin Ryan, he proves to be a fan favorite as well; always imparting his charm, wit, and wealth of obscure knowledge. Season 5 proved to be an eventful one for Dever as we delved further into his character’s marriage to his longtime girlfriend who is coincidentally portrayed by his real-life wife, Juliana.

In addition to "Castle," Dever has played authoritative figures on the likes of "Army Wives" and "General Hospital;" both of which had him starring as a doctor. Other forays into television include "Mad Men," "Drop Dead Diva," NCIS," and all three "CSI" franchises. He's also appeared in such films as "Hollywoodland" with Adrien Brody and Ben Affleck, and the independent comedy "Ready or Not.”
Well known to theatre audiences, Dever assumed the iconic role of Alex in A Clockwork Orange for which he received rave reviews and nominations for an Ovation, Garland, and Los Angeles Drama Critics Circle Award. Another highlight amidst his over 60 plays and musicals is his notable performance in iWitness at The Mark Taper Forum.
Born in Flint, MI, Dever and his family moved to Bullhead City, AZ when he was six-years-old. He successfully transitioned to Valedictorian of his high school and later received a Bachelor's in theatre in a mere three years at Northern Arizona University. He was then accepted into the graduate program at the prestigious Carnegie-Mellon University and The Moscow Art Theatre for which he is the youngest person to earn his Master's degree. Dever is also a lifetime member of the renowned Actor's Studio.
He and his wife reside in Los Angeles with their two rescue dogs and are active in animal rights, environmental causes, and proud vegetarians.
