"I, Claudia is blissfully funny and unexpectedly touching."

Richard Ouzounian, Toronto Star

"Kristen Thomson's portrait of a wonderfully winsome young woman trembling on the cusp of adolescence is one of the freshest things to hit the stage in many a season... I, Claudia is blissfully funny and unexpectedly touching... Kristen Thomson is the real theatrical thing... she can rock her audience—she certianly rocked me—on a regular basis with lines and moments that are hilariously funny, totally unexpected and unimpeachably true."
