Personal life
Brandt is the only biological child of her parents, Greg and Robin, respectively of German and mixed Danish-Swedish descent. She has an adopted sister, Marissa Brandt. Her parents struggled with infertility for the first 12 years of their marriage and decided to adopt a child. They chose to adopt from South Korea partly because Greg's sister had adopted two boys from that country and adopted an infant girl, naming her Marissa. About two weeks before Marissa was set to arrive in the U.S., the couple found out that Robin was pregnant; she gave birth to Hannah about six months after Marissa joined the family.[18]
The sisters were originally involved in figure skating as small children, but Hannah switched to hockey at age 5, with Marissa following suit a few years later. They then played on the same teams until Marissa graduated from Hill-Murray School a year before Hannah; Marissa went to NCAA Division III school Gustavus Adolphus College while Hannah went to Minnesota. Both won gold medals at the 2017 IIHF Women's World Championships—Hannah for Team USA in the top division, and Marissa for South Korea in Division II (the third level) under her birth name of Park Yoon-jung.[19] The sisters played in the 2018 Winter Olympics.[18][20]
