Her off-Broadway credits include A New Brain and Groundhog. Her other theatrical credits include mountings of Kiss of The Spider Woman, The Book of Candy, The Predator's Ball, Man of La Mancha and No Way to Treat a Lady.

Pawk played her final pre-absence performance on December 11. Mamma Mia! will continue to star Pawk's husband, John Dossett, as Sam, Carey Anderson as Sophie Sheridan, Judy McLane as Tanya, Olga Merediz as Rosie, Andy Kelso as Sky, Mark L. Montgomery as Bill and David Beach as Harry.
