|Psych (detective agency)|
|Location:||Santa Barbara, California, U.S.|
|Last appearance:||The Breakup|
Shawn started and named the agency without Gus's knowing, and called it Psych, saying the best way to make people believe you is to tell them that you're lying to them. He used Gus's credit card and forged his signature on the lease. Since the first season they have extended the office to have more rooms. The Psych office is like a second home to both Shawn and Gus with it's own bathroom, kitchen, and entertainment system.
Shawn and Gus do receive clients through their psychic detective agency but the bulk of the investigations come from involvement with the Santa Barbara Police Department. The Psych detective agency also tends to uncover past cases which wrongly incarcerated people or closed due to lack of evidence.

- The color of the "Psych" logo changed from blue to green somewhere in between Seasons 1 and 2. In season 1, episodes 12, 13, & 14, there's inside window shots where it looks to be green and also In Scary Sherry: Bianca's Toast, it was a night time shot, but appears to be green. Definitely though, first episode of Season 2 " American Duos" it was green.
