Emmy award winner Jonathan Katz, the co-creator and star of Comedy Central’s critically acclaimed animated series "Dr. Katz, Professional Therapist," is an accomplished standup comic, musician, actor, and writer, Katz, who starred in his own HBO Half-Hour Comedy Special, just inked a deal with NBC to create his own situation comedy. He was featured in the final season of HBO’s "The Larry Sanders Show" and recently had a recurring role on CBS’s "Ink" as Leo "the angel of death" (head of business affairs). Katz just completed a two-year deal with DreamWorks Television where he created and wrote television pilots for both ABC and NBC. He has been a frequent guest on "The Late Show with David Letterman," "Late Night with Conan O’Brien," and "Politically Incorrect with Bill Maher".

A native New Yorker, Jonathan moved to Boston fourteen years ago and currently resides in Newton, Massachusetts with his wife and two daughters. His film career was launched when he co-wrote the story with Pulitzer Prize winning author David Mamet on which the critically acclaimed film "House of Games" was based. Katz was singled out by The New York Times for his performance as Jackie Shore in Mamet’s film, "Things Change." He also appeared in Mamet’s recent film, "Spanish Prisoner" and will soon be seen in the feature film "The Independent." He has had feature film commitments at both DreamWorks Films and FOX 2000.

Originally a musician and songwriter, Jonathan fronted a rhythm and blues group called "Katz and Jammers" before serving as the musical director for Robin Williams’ 1979 stand-up tour. In 1981 Katz started working solo, doing a cabaret act that was still mostly musical, but in between songs, he started laying the foundation for his stand-up act. "I noticed that people would get very chatty during the songs but then when I stopped singing they would tune in. So I started singing less and talking more."

In 1995, Katz won an Emmy for Outstanding Voice-Over Performance for his role as Dr. Katz, garnering Comedy Central its first Emmy. The show has been heralded by both Time Magazine and TV Guide as one of the 10 best shows of the year, was voted the Cable Ace Award for Best Animated Series, and won a 1998 Peabody Award for Excellence in Broadcasting. Katz created the show with software developer Tom Snyder and is currently starring in and producing the sixth season. Additionally, Jonathan is working on his first book, "To Do Lists of the Dead."
