Griffith began his writing career on
Santa Barbara in 1988 and continued writing for the show until 1991 when he moved over to
One Life to Live, where he began as an associate head writer under
Michael Malone before being promoted to co-head writer in early 1992. Under his and Malone's tenure at
One Life to Live, the show won a Daytime Emmy Award for Outstanding Writing in 1994. Griffith left the show in early 1995. In 1997, Griffith was co-creator of the
NBC Daytime soap opera
Sunset Beach along with
Robert Guza Jr. The show ran for nearly three years before being cancelled in December 1999. In the spring of 2003, Griffith and Michael Malone returned to
One Life to Live for a second stint as head writers, however they remained with the show for just a year. After leaving, Griffith became a script writer on
CBS Daytime's
As the World Turns under head writer
Hogan Sheffer, who shortly afterwards stepped down as head writer. He would later return to the show briefly between 2009 and 2010. In 2006, vice president of CBS Daytime,
Barbara Bloom, brought Griffith over to
The Young and the Restless as a creative consultant and breakdown writer under executive producer and head writer
Lynn Marie Latham; within three months, he was promoted to co-executive producer to work alongside of Latham. Griffith assumed full executive producer duties after Latham was fired for joining the
2007-2008 Writers Guild of America strike. During the strike, Griffith became a
strikebreaker, adopting
financial core status so that he could work while Guild members were on strike. In December 2007,
Maria Arena Bell became his co-head writer. In August 2008, Griffith was fired from his executive producer duties by
Barbara Bloom and
Steven Kent of
Sony Pictures Television, leading to Bell becoming executive producer and head writer and later replacing him with
Paul Rauch. In 2009, Griffith briefly worked as a writer on
General Hospital. In July 2012, it was announced that Griffith had been rehired on
The Young and the Restless as the sole head writer following Bell's dismissal; he would work alongside new executive producer
Jill Farren Phelps. Episodes under their direction began airing on October 12, 2012. In August 2013, speculation and reports indicated that Griffith had resigned as head writer, reportedly due to "creative differences" with Phelps. Further speculation adds that
Shelly Altman may take over as the new head writer, alongside
Tracey Thomson or
Jean Passanante may be brought aboard as a new co-head writer. In February 2015, Griffith was hired as co-head writer of
Days of Our Lives, alongside re-hired former head,
Dena Higley. Griffith began his role as co-head scribe on February 16, 2015, with the material airing on August 19, 2015. In February 2016, it was reported that Griffith would be departing
Days of Our Lives as co-head writer, with Ryan Quan serving as his replacement. Griffith's last episode aired on September 2, 2016. In August 2018, it was reported that Griffith would be returning to
The Young and the Restless this time as supervising producer. Griffith's first episode as supervising producer aired on September 14, 2018. In December 2018,
Daytime Confidential reported that Griffith would once again act as ''The Young and the Restless's'' Head Writer following the departure of
Mal Young. Griffith, formerly a member of
Writers Guild of America, East, left and maintained
financial core status during the
2007–08 Writers Guild of America strike. ==Positions held==
