Born in Grand Rapids, Michigan as Julie Brandt, she took up inline speed skating, and won two gold medals at the U.S. Olympic Festival in 1995.

She was overall sprint champion at the U.S. nationals that year, and again in 1998, also winning the Downer's Grove Championship in 1996 and 1998, and taking a gold medal at the World Cup in 1997.

She took a break from skating during which she married Doug Glass, a fellow speed skater, then returned to win a silver medal at the 1999 Pan American Games.

[4] Glass took another break from skating in 2002, during which time she and her husband ran a roller rink and drive-through coffee shop in Lebanon, Oregon.

[13] In June 2020, Glass and Mota Skates came under fire for posting racially inflammatory graphics across multiple social media platforms.

The Women's Flat Track Derby Association (WFTDA) removed Mota Skates as a vendor from all future events, stating "[w]e feel that our values are no longer aligned.

A far cry from the prior month's voiced support for Black Lives Matter, the co-owner couple now claimed the Black Lives Matter movement was actually a "terrorist funded corrupt [sic], hateful & racist organization" that was "funded by Soros," while lambasting anyone who vocalized criticism of the brand as being racist themselves, writing in part:NO one should ever tell others to shut up, listen and learn/obey.

We will end it with our frustration and confusion why the BLM movement is not going to all large cities around the country using the millions they raise through donations to stop the killing our children and ALL Black Lives..
