Mary Seraphinoff is the head of Detroit's SMACNA chapter and the president of Allied Ventilation in Warren, Mich.
"It just seems like I end up switching hats very often," she said. "There are so many different things going on, sometimes I feel like I am a juggler." Seraphinoff does keep busy. She and her husband Nick own and operate Allied Ventilation, a sheet metal shop in this city just outside Detroit. But in addition to overseeing a company with more than $10 million in sales each year, Seraphinoff serves as president of the metropolitan Detroit chapter of the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) as well as on the chapter's board of directors.
