When Mary Starkey sold her Cap Hill mansion last week, she said “Thank you.” “When I said goodbye to the mansion, I thanked it for its service to Starkey International. It’s been an amazing building, and I’m actually quite happy that it will continue to serve,” she said. Starkey’s business, the Starkey International Institute for Household Management, trained butlers and maids to serve in the homes of high-class families for decades.
