Page Joseph Falkinburg, the eldest of three children, was born in Point Pleasant, New Jersey, the son of Sylvia (nee Seigel) and Page Falkinburg Sr. Falkinburg was raised by his father during his early years, after his parents divorced. The name "Dallas" came from his love of the Dallas Cowboys. His brother, Rory, and sister, Sally, were raised by their maternal grandmother.

When WCW was purchased by WWF owner Vince McMahon in 2001, Page was one of the few major WCW stars (along with Booker T and Buff Bagwell) who accepted buyouts of their AOL Time Warner contracts in order to immediately sign with McMahon. He debuted in the World Wrestling Federation (WWF) on the edition of June 18, 2001 of Raw when he unveiled himself as the stalker of The Undertaker's wife, Sara. Page revealed he didn't care about Sara; he only did it to make an impact and wanted to take on the biggest dog in the yard. Page soon joined the Alliance during the WCW Invasion. At King of the Ring, he fought The Undertaker in an unsanctioned brawl that was never announced as an official match.  Page and Chris Kanyon reunited on the edition of August 6, 2001 of Raw when Kanyon helped Page attack The Undertaker backstage. Three days later on edition of August 9, 2001 of SmackDown!, Page and Kanyon defeated the APA to win the WWF Tag Team Championship.  The feud with the Undertaker went on for the best part of three months and ended when Undertaker and Kane defeated Page and Kanyon at SummerSlam on August 19, 2001 in a Steel cage match for the WWF Tag Team Championship, where Page got injured which kept him out of action until late October 2001.  He became known for his catchphrase "Yo! It's me, it's me, it's DDP!" While Page was injured he developed a new gimmick in September 2001 to become a motivational speaker, something he did in real life, in what came to be known as his Positively Page character. The name came from the title of his autobiography that was published during his WCW days. The character, who Page developed after attending the Tony Robbins Results 2000 seminar in October 2000, involved Page constantly smiling and acting optimistic, with his trademark phrase "That's not a bad thing... that's... a good thing".  His return televised match was on November 3, 2001 at Rebellion losing to Big Show. After the Alliance lost at Survivor Series DDP along with the rest of the alliance members bar Test kayfabe lost their jobs.
