JustAnswer is a Bay Area-based online question-and-answer service that connects users with experts in various subjects. Just about one year ago, Julia spoke with the company's founder/CEO Andy Kurtzig and his daughter Jamie about their decision to travel to the Ukrainian border during spring break to deliver medical supplies and help refugees. Since then, JustAnswer has been in the western city of Lviv to treat Ukrainians suffering from PTSD and other mental health conditions. Andy Kurtzig rejoins the show today from Lviv.
