Tom Grummett began providing finished artwork over George Perez's layouts on The New Titans #58 in 1989. He worked with Marv Wolfman and Pérez on the "A Lonely Place of Dying" story line which introduced Tim Drake as the new Robin. Grummett remained on The New Titans after Perez's departure and helped Wolfman revitalize the title. He began a long association with the Superman franchise when he drew Action Comics #665 and then helped writer Louise Simonson and artist Jon Bogdanove launch a new title, Superman: The Man of Steel in 1991. Grummett drew part of The Adventures of Superman #480 (July 1991) and became the main artist on that series with the following issue and then worked on the "Panic in the Sky" crossover in 1992. During his run on The Adventures of Superman, Grummett and writer Jerry Ordway (along with editor Mike Carlin, Dan Jurgens, Roger Stern and others) were the architects of "The Death of Superman" story line, in which Superman died and was resurrected. It was during that story line, that Grummett and writer Karl Kesel, created the new Superboy in The Adventures of Superman #500 in 1993.

Tom Grummett drew parts for DC Comics' other major event of the early 1990's, Batman: Knightfall, contributing parts of Knightquest and KnightsEnd. Grummett launched an ongoing Robin series in November 1993 with writer Chuck Dixon and a Superboy series three months later with writer Karl Kesel. In 1995, writer Roger Stern and Grummett created a new quarterly series, Superman: The Man of Tomorrow. He was one of the many artists who contributed to the Superman: The Wedding Album one-shot in 1996 wherein the title character married Lois Lane. Other work for DC included collaborating with Chuck Dixon on a Secret Six one-shot in 1997 as part of the Tangent Comics imprint and co-creating the Power Company series with writer Kurt Busiek in 2002.

In 2000, Tom Grummett and his former Superboy collaborator Karl Kesel created Section Zero as part of the Gorilla Comics imprint at Image Comics. Gorilla Comics was intended to be a creator owned company financed by a comics related website, www.eHero.com. The website proved to be a financial failure, leaving the creators to personally finance their own books. Along with the other Gorilla Comics creators, Kesel and Grummett attempted to continue the series they started, but these efforts proved to be unsuccessful. In January 2012, Kesel announced that he and Grummett would be relaunching Section Zero as a web comic on the Mad Genius Comics website. The previously published stories were posted on the site and new material was added as it was completed.

At Marvel Comics, Tom Grummett completed a run as penciller on Thunderbolts, with writer Fabian Nicieza and inker Gary Erskine in 2007 and in 2009 he co-created the X-Men Forever series with Chris Claremont. The artwork of Tom Grummett is currently creditited in 625 separate Comic Book issues.
