“DiCostanzo shines as Valli, the driving force in the show...He exhibited sharp timing and goes from a great impersonation to a believability that brings the reality of the show to the forefront.”

MD Theatre Guide - Brian Bochicchio

"...has the pipes and charm to portray frontman Frankie Valli. With a soaring falsetto, DiCostanzo leads the cast and is a vocal powerhouse. His rendition of “Fallen Angel” rivaled Valli’s own recording, seeming as heartfelt and anguished, a father mourning the loss of his troubled child.”

DC Theatre Arts - Jeffrey Walker

as frankie valli

"...delivered an unforgettable performance, embodying the legendary singer’s signature falsetto with jaw-dropping accuracy. Every high note was a showstopper, and the emotional depth he brought to Valli’s journey...was nothing short of mesmerizing. Songs... weren’t just performed; they were lived.”

BroadwayWorld - The Marriage Matinee

"...astonishing performance. His portrayal of the singer goes beyond his impressive Valli-like vocal talent. DiCostanzo brings a range of polished acting skills to the role as well.
