[citation needed] Whitmer feuded with "Ice Cream Man" Tony B. before forming a tag team with Jamie Knoble in 2002.

[citation needed] On May 8, 2002, he won the HWA Cruiserweight Championship by defeating Knoble, Shannon Moore, and Matt Stryker in a four-man elimination match.

[citation needed] In June 2001, Whitmer toured Japan with Pro Wrestling Noah, teaming on several occasions with fellow gaijins Matt Murphy and 2 Cold Scorpio.

The events on December 22 led to a match on January 10, 2004, at The Battle Lines Are Drawn between The Second City Saints (Punk, Cabana and Ace Steel) and The Prophecy (Daniels, Maff and Whitmer).

The match descended into a brawl, and the referee declared it a no contest after Lucy returned to ROH for one night, slapping Whitmer to gain a measure of revenge.

They defeated the Saints for the ROH World Tag Team Championship at Round Robin Challenge III on May 15, but lost the title to the Briscoe Brothers later that evening.

After the match, Maff convinced Whitmer to discard both The Prophecy's name and the managerial services of Allison Danger, claiming that they no longer needed a leader or a manager and resulting in both men turning face.

Whitmer formed a new team with Jimmy Jacobs, and defeated Samoa Joe and Jay Lethal in a match for the vacant title on April 2.

Jacobs also cost himself and Whitmer the Tag Team Title the following night at Dissension against the champions Roderick Strong and Austin Aries.

[3] In September 2007, he allied with Brent Albright and Adam Pearce to form The Hangmen Three (also spelled as The Hangm3n), which later saw them gain Shane Hagadorn as their manager.

[7] While a member of The Hangmen Three, Whitmer challenged for the World Tag Team Championship on a number of occasions with either Pearce or Albright, but was unsuccessful in regaining the title.

On September 9, Whitmer made his debut for Dragon Gate USA, competing in a six-way elimination match, which was won by Brodie Lee.

Whitmer's first internet pay-per-view appearance for Dragon Gate USA took place on November 11 at Revolt, where he defeated Vinny Marseglia.

[15] August 3 at All Star Extravaganza, Whitmer entered a tournament for the newly vacant World Championship, where he faced Bennett in a first round match.

[16][17] On September 20 at Death Before Dishonor XI, Whitmer announced his retirement due to the neck injury he suffered from Bennett's piledriver.

[18] On December 14 at Final Battle 2013, Whitmer came out of retirement and teamed with Eddie Edwards in a winning effort against Jay Lethal and Roderick Strong.

After the match, Whitmer turned heel by attacking Edwards with the assistance of Strong and former tag team partner Jimmy Jacobs.

[19] Whitmer then reunited with Jacobs and they both allied with Strong to form The Decade, with the stable's name being a reference to all three men's long tenures with the company.

On the January 4, 2014, The Decade secured its first victory as Whitmer and Jacobs defeated Adam Page and Mark Briscoe in a tag team match.
