Dr. Jesse Travis started out as an intern under the guidance of Mark, and is currently a resident in the Community General emergency room and something of a "second son" to Mark Sloan. He really admires the relationship Mark and Steve have, something he wishes he could have with his own father, Dane Travis, who he has rarely seen since his parents divorced. That's because, as Jesse learned recently, his father was an intelligence agent working abroad. Jesse is an extremely competent and capable doctor, though he's only an apprentice when it comes to investigating crimes.

He was brought up by his mom in Elgin, Illinois where everyone is crazy about baseball. He's enjoying learning the mechanics of surfing, but he hates boats as he suffers from sea-sickness. He used to have a VW (CA Plates 30KL97), once nearly died from a mutated smallpox virus, and loves country music.
