This Brooklyn born performer studied acting at The New York Academy of Theatrical Arts and The Lee Strasberg Theatre Institute. While studying his craft, Vaughn developed his unique stand up comedy act and began appearing in comedy clubs and universities around the country.

Vaughn then moved to Los Angeles and was welcomed into the improvisational comedy inner-circle as a member of "The Groundling" and "Off The Wall" where he worked with such notables as John Ritter, Robin Williams and Phil Hartman.

Following Vaughn’s first very successful guest shot on The Tonight Show, he has been invited for return appearances several times.

In addition too stand-up comedy, Vaughn has acted on many popular sitcoms and wrote for the hit series, The Golden Girls. He also co-wrote several of Gallagher’s Comedy Specials for Showtime.

With strong visual and vocal resemblances to a young Frank Sinatra, when Vaughn would improvise a love song on stage, the audience would swoon and yell out, "Frankie." Although Vaughn was making a name for himself in comedy, one night, on a dare, Vaughn entered a singing contest held in a local nightclub…and won! The grand prize was a sing appearance at the Hollywood Palladium. The response was overwhelming. Soon word of the "young Sinatraesque" character spread quickly and Vaughn was suddenly in demand to perform at prestigious private parties and corporate events. Among them: the wrap parties for the movie "Volcano", "City of Angels", and for such entertainment luminaries as Danny DeVito and Hugh Hefner.

Vaughn was names winner of the Jeffrey Foundation’s "Frank Sinatra Sound A Like Contest" and was further honored with The Southern California Motions Picture’s Council’s "Bronze Halo" and "Jeanie Platinum" awards.
