A few years before joining Sesame Street, she had auditioned for the role of Mr. Snuffleupagus after Michael Earl left the show. She didn't get the part, but she eventually became a Muppet performer in 1982.
Arciero earned her Master's in Puppetry from the University of Connecticut and has performed characters for numerous shows outside of the Muppet sphere, including The Great Space Coaster, Allegra's Window, Between the Lions (replacing Kathryn Mullen as Leona), Eureeka's Castle, and Lomax, the Hound of Music (as Louise)
She has also been active in the world of theater, including a stint at the Orpheum Theater with Little Shop of Horrors, and serving as director for several live shows at Sesame Place and El Capitan Theater in Los Angeles.
Arciero has served as Artistic Director for the prestigious O'Neill Puppetry Conference since 2002 and continues to participate in puppetry workshops and other events across the country. She is also a graduate of The University of Connecticut's Puppet Arts program.
