The first play Shores wrote was Daddy's Dyin' (Who's Got the Will?) which saw a 1987 debut in Los Angeles. The comedic play was adapted for the 1990 film Who's Got the Will?. Shores wrote the screenplay and executive produced the feature.
Perhaps Shores' best known play is his fourth, "Sordid Lives", which debuted in 1996 in Los Angeles. The comedy centered around the Texan Ingram family and touched on LGBT themes. In 1999 Shores wrote and direct the screen version of Sordid Lives. Eight years later Shores produced 12 prequel episodes of "The Series" which aired on US gay interest cable channel Logo.
In 2010, Shores debuted his play "Yellow" at the Coast Playhouse in West Hollywood.
Shores has two daughters Caroline and Rebecca from a previous marriage to Kelley Alexander. He is married to his partner and co-producer, Jason Dottley, since 2003, and they remarried in a state where same-sex weddings are recognized in 2008.
