Classmates help U-M student expand business helping older adults with tech during pandemic Meredith Bruckner, Community News Producer, All About Ann Arbor Published: Tags: ANN ARBOR – When Brett Wolff launched his business Grandson on Call, he was still in high school. “When I was 14 or so, I would help my grandparents out a lot with their, computers, phones, iPad technology etc.,” said Wolff. “It was my grandfather’s idea to offer services to other people.” What began as free classes offered at assisted living communities transformed into private lessons with Wolff working 10-15 hours a week outside of school. “I really, really enjoy doing it,” said Wolff. “I had one private client who was older and had trouble traveling -- this was way pre-COVID -- but her first great-grandchild was born and we were able to FaceTime with her granddaughter with the baby and she started crying. She was just so happy to be able to see her great-grandchild.”
