In 1982, at the age of nineteen, Leslie began serving as a bartender at Hammerjack's Concert Hall and Nightclub, a famous rock and roll-oriented nightclub and one of largest and most popular indoor bar venues on the east coast (since razed). Glass would frequently dress in sexy clothes, including lingerie, and dance on the bar; she quickly became one of the most popular bartenders. Throughout the 1980s, Leslie manned the most prominent bar in front of the concert stage that frequently featured acts such as Kix, Joan Jett, Ted Nugent, and Guns N' Roses. Later, she founded and managed a women's lingerie and bikini dance troupe that was a regular feature. Leslie became a feature dancer at Memories Strip Club in Dundalk, Maryland.

Leslie was first diagnosed with colon cancer in 1998. After surgery to remove part of the colen & and ovary she was given 2 weeks to live. When diagnosed, Leslie was already at stage 4 of her cancer as it had already matasitzised to her liver and consumed an ovary. Leslie found oncologist, Dr. David VanEcho at the University of Maryland Medical System Marlene & Steward Greenebaum Cancer Center in Baltimore Maryland. She was the first person in the USA to receive an experimental cocktail of chemotheropy drugs. This produced dramatic results. However, her good fortune did not continue and the cancer stopped responding to the drugs. Tumor ablation was used to "microwave" tumors on her liver and she continued to try different chemotherapies throughout the two years she survived after her diagnosis. During this thime she continued to work and made appearances on television and elsewhere to discuss the disease. Leslie fought for two years before succumbing on August 4, 2000. Her death evoked a rare tribute piece from Penthouse magazine's normally unsentimental editors.

In 1996, Leslie married Ghyslain Lacoste of Hollywood, Florida, who survives her.
