She and husband Thomas found the best medical care for her daughter's condition at Children's Hospital of Philadelphia.
But once Jenn delivered daughter Lucy, where could the Lebanowskis stay for the weeks, or maybe years, her newborn needed at CHOP?
Jenn found the answer in Hosts for Hospitals, a Philadelphia-based non-profit which finds housing for patients and family members coming here for living-saving treatment.

Her "Minneapolis loves Philly" appeal is aimed at celebrating Super Bowl 52 by raising at least $5,200 for Host for Hospitals, so other patients can feel the warmth and reassurance of a private at these nerve-wracking time
