She was the middle of the Shannon sisters, with Holly being her younger sister, and Ashley Shannon being her older sister. Her family was in heavy debt due to their ancestors, which meant that her family was fairly poor. She dated Myles Nichols (Silverton at the time) though many people thought she was dating himf or his money. In that same year, her father committed suicide, not being able to handle the debt his family had. Myles and Heather were voted best couple, and prom queen and king in their senior year. Heather took a job at Castle Food N' Drug after graduating. It was then that Myles was discovered to not be a Silverton. Her mother was diagnosed with cancer, and her older sister helped to take care of her. In 2010 Heather and Myles got married, and moved into their own place. Heather's mother died in 2009. It was then her sisters took jobs at The Midnight Lounge to pay off their debt. Heather feels bad for not contributing more, but wants to live her own life as well -- and feels they should be fighting the debt instead of paying it.
