[2] In 1987, Stillwell moved to Los Angeles, where he served as production assistant and script coordinator for Star Trek: The Next Generation.
Stillwell went on to serve from 1999 to 2005 as Vice President of Operations for Piller², the production company created by Trek scriptwriter and producer Michael Piller.
Stillwell co-wrote the TNG episode "Yesterday's Enterprise," a fan favorite, in 1990, and briefly took a turn before the camera as a Klingon extra in 1991's Star Trek VI: The Undiscovered Country.
During Stillwell's administration, he presided over structural reorganizations within the group, restored good relations with the Star Trek Welcommittee, and increased the group's visibility by publicizing with Starlog, Susan Sackett (Trek creator Gene Roddenberry's personal assistant), and notable fandom figure Bjo Trimble,[3] leading its figures to swell toward 3,000 fans.
Following the death of producer Michael Piller in 2005, Stillwell joined the FOX Broadcasting Company in the Alternative Entertainment department on shows including American Idol, So You Think You Can Dance, and The X Factor, as well as specials like the annual Teen Choice Awards, the American Country Awards, and the occasional Emmy broadcast.
