Dr. Will Casey is a main character in the Frasier-based fan fiction spin-off Crane Life.
Will is an easy-going and fun-spirited psychiatrist who often gets on the other character's nerves. Nevertheless he makes many friends during his years at Mead Psychiatry and is a respected therapist.
Will first appears in the pilot as a foil for Dr. Niles Crane when they are forced to share an office. Towards the end of Season 3, Will accepts a regional management position in New York City and departs the practice.
Throughout his first tenure with Mead Psychiatry, Will sleeps around with a lot of women and often causes controversy. Halfway through Season 2, he embarks on an affair with a med student, which is frowned upon by his moralistic colleagues.
