Warshaw started
Bloodshot Records in 1993 with co-founders Rob Miller and Eric Babcock as a hobby that they ran out of her apartment in the
Wrigleyville neighborhood of Chicago. They were trying to shine a light on some of the unheralded music they were listening to and seeing in the local Chicago clubs at the time. As of early 2019, Warshaw resigned from Bloodshot, and, as of late 2020, she and remaining co-owner Miller remained in active litigation. In addition to her work at the label, Warshaw is involved in healthcare reform activism. In 2006, she helped to organize benefits to support
Fitzgerald's sound engineer Gary Schepers cover healthcare related expenses. She was the small business owner representative for Illinois on the White House website for health care reform under
President Barack Obama. She was an active supporter of the
Affordable Care Act. == Personal life ==
