Schon's first acting credit was in 1990 when he played Gillan and Gaias in the TurboGrafx CD video game Valis II. Two years later after his debut, he played Frank II and Mirabelle in The Naked Truth and two years after that, he played Daryl O'Melveny in A Kiss Goodnight.

For many years, he was Nathan Lane's voice double, taking over the role of Timon in The Lion King's Timon and Pumbaa and singing the title song as well. He appeared in over 120 episodes of that series. He reprised the role of Timon in The Lion Guard and House of Mouse. He understudied for Lane on the animated series Teacher's Pet for ten episodes, while Lane was busy with Mel Brooks' musical of The Producers. Schon also voiced Snowbell in Stuart Little: The Animated Series and Stuart Little 3: Call of the Wild, once again replacing Nathan Lane. For three years, he was the "comedy voice" of the ABC television network, voicing all promos for their comedies (Home Improvement, Drew Carey, Roseanne, and Ellen, among others) and was the promo voice for Politically Incorrect when it moved from cable to ABC. Kevin's voice appears in over 40 episodes of Married... with Children, with two on-camera appearances.

He also voiced Lob-Star in Skylanders: Trap Team and Skylanders: SuperChargers, Otto in Ben 10: Omniverse, Activist in Infamous Second Son, Officer What in Jack and the Beanstalk, Roboy in Bubble Guppies, Onyx in Sofia the First, Dead-Eye in Jumanji, Male Patron and Male #2 in The Angry Beavers, Announcer and Weatherman in Rugrats, Velocirraptor, Peasant, Waiter and Reporter in I Am Weasel, Conductor and Hyena in Cow and Chicken, Thrakhath and Blizzard in Wing Commander Academy, Major Taibot, Abomination, Judge, Samual Laroquette and Zzzax in The Incredible Hulk, Stash in The Nuttiest Nutcracker, Muc, Luc, Wolverine 1 and Simpson in the Balto franchise, Pongo in 101 Dalmatians: The Series, Grimskull and Prince Joshua in Skeleton Warriors, Merdude and Alim Coelacanth in Teenage Mutant Ninja Turtles, Narrator in State to State, Chungu and Thurston in The Lion Guard, Elderly Peter Pan and In in Disney's Villains' Revenge, Happy in House of Mouse, VEGA and UAC Soldier in the 2016 video game Doom and provided additional voices for Battlefield: Hardline, Ben 10: Omniverse, Family Dog, Invasion America, Star Wars: Knights of the Old Republic, Doom and The Twisted Tales of Felix the Cat. In addition, he is known by cartoon "cultists" everywhere for his work on The Tick - voicing both villains and superheroes.

In late 2003, he produced More, an autobiographical one-woman show written and performed by Yeardley Smith (voice of Lisa on The Simpsons), at the Union Square Theatre in New York City. The show was critically acclaimed, but financially unsuccessful.

He was co-producer of Bat Boy: The Musical in the United Kingdom, first in a limited run in Leeds, then in a full-scale West End production at the Shaftesbury Theatre in London. Even though most press reviews were scathing, one notable exception - The Evening Standard - took up the cause for what became a groundbreaking cult classic which is now one of the most often-produced musicals in America. Film director John Landis was brought in to see the West End production and enthusiastically signed on to direct a film version. Though a film screenplay was written by the original authors under the guidance of Mr. Landis, the producers lost the rights to the property, the authors proved recalcitrant, vindictive and uncooperative, and the film remains unproduced.
