Rollie Krewson (sometimes credited as "Rollin Krewson") is a puppet designer and builder known for her work on various Muppet productions. She interned with Jim Henson's company in the mid-1970s. Although she now works primarily as a designer/builder, she began as a performer, doing small bits on The Muppet Show and other projects. She has contributed to almost every Henson production since her arrival, and to this day carries her skills through on Sesame Street.
Krewson has received seven Daytime Emmy Awards for her contributions on Sesame Street and has been nominated many times for her work on other Henson productions.
