Business career
DeVos is chairwoman of the Windquest Group, a privately held operating group that invests in technology, manufacturing, and clean energy. DeVos and her husband founded it in 1989.[21]
DeVos and her husband were producers for a Broadway run of the stage play Scandalous: The Life and Trials of Aimee Semple McPherson, in 2012, based on the life of the famous evangelist and featuring a book and lyrics written by Kathie Lee Gifford. The show ran for three weeks, closing in December 2012[47] after negative reviews from Variety,[48] The New York Times[49] and others.[50][51]
Neurocore
Betsy and her husband Dick are chief investors in and board members of Neurocore, a group of brain performance centers offering biofeedback therapy for disorders such as depression, attention deficit disorder, autism, and anxiety.[52][53][54] The therapy consists of showing movies to patients and interrupting them when they become distracted, in an effort to retrain their brains. According to The New York Times, a review of Neurocore’s claims and interviews with medical experts suggest that the company’s conclusions are unproven and its methods questionable.[52] Democratic senators raised concerns about a potential conflict of interest and questioned whether she and her family members would “benefit financially from actions” she could take as education secretary. DeVos announced that she would step down from the company’s board but would retain her investment in the company, valued at $5 million to $25 million.[52][55][56]
