Noreen "Nora" Kristina Greenwald is a two-time former WWE Women's Champion and one of the few women to hold a male title in WWE, holding the WWE Hardcore Championship on one occasion. Moreover, while working in WCW, she trained many of the female wrestlers at the WCW Power Plant. Aside from professional wrestling, Greenwald is heavily involved in church activities and spends her time doing missions work in Guatemala.

Nora Greenwald appeared for only one match in October of 1998 as Starla Sexton, where she wrestled for the WWF Women's title and lost to an overpowering opponent - Jacqueline. Unsuccessful in her bid for the Championship belt she moved on to the WCW as "Miss Madness '99" during Randy Savage's return in mid 1999. Besides working alongside the Macho Man she was one of two people (Madusa was the other) who actually trained Gorgeous George for her match against referee Charles Robinson.

After being fired as Miss Madness in July '99 by the Macho Man and leaving the Miss Madness name behind, Mona (her new persona) proved herself as a devastating competitor in the ring. By utilizing solid wrestling techniques along with her aerial gymnastic abilities, she removed herself from being just a Macho "tag-along" and showed her capability to become an entertaining solo wrestler in just a few months.

In 2000, after months of conflicting Internet rumors about her being fired and not being fired from the WCW Nora appeared in the WWF in November as Molly Holly, a cousin of Crash Holly

In September 2001, Molly became Mighty Molly, the superhero sidekick of The Hurricane. Molly, however, eventually left The Hurricane to become a full-time solo wrestler, taking his Hardcore Championship after whacking him with a frying pan at WrestleMania XVIII on March 17, 2002 in Toronto. She promptly lost it to Christian an hour later after getting a door slammed in her face.

In April 2002, she returned to her previous ring name, Molly Holly. Upon her return to the newly renamed World Wrestling Entertainment (WWE), she drastically changed her look by shortening her trademark blonde hair and darkening it to autumn brown. Greenwald's reasoning behind this was that it fit her new character better. Greenwald adopted a self-righteous prude gimmick, similar to that of the Right to Censor faction, as she was kayfabe appalled by the other WWE Divas continually using their "assets" and degrading themselves. During this gimmick, she would often refer to herself as being "pure and wholesome."

This led to a feud with the then-Women's Champion Trish Stratus, which culminated in her winning the championship at King of the Ring 2002 in June. The feud with Stratus continued for several months, and Molly later brought in Victoria as an enforcer to help deal with Trish. She would finally drop the title back to Stratus at Unforgiven 2002 in September.

Greenwald earned her second WWE Women's Championship by defeating Gail Kim on RAW on July 28, 2003. Kim would later turn heel and join Greenwald in her feud with Stratus.

Greenwald lost her championship to Victoria in a Fatal 4-Way Match on February 23, 2004. She would feud vehemently with Victoria for the next few months, believing she had been robbed of her title. The feud led to a Hair vs Title match at WrestleMania XX in March 2004, which Greenwald lost when she tried to execute Victoria's Widow's Peak. The move was reversed, resulting in Greenwald having her head shaved. Over the next few months, she desperately tred to disguise her bald head using loose-fitting wigs.

She left WWE and a full-time wrestling career in April 2005. Reportedly, she was beginning to become disenchanted with WWE, who began to focus on looks rather than wrestling ability.

Since leaving the WWE Nora has appeared at several indy shows as a guest referee or signing autographs.
