Karen graduated from Parkside High School in May 1971. In February 1974, she and Dan started Rothenberger Construction Inc. just months before the birth of their first son, James. Two short years later in 1976 she gave birth to their second son, Jeremy. She maintained her position as company secretary/treasurer while raising their two sons and running their household. Her role in the growth and success of Rothenberger Construction cannot be overstated. Karen enjoyed watching sports, particularly anything her children and grandchildren played. She was a loyal fan to her Detroit Lions, through decades of 4th quarter letdowns. She loved the game of golf, and particularly loved her Monday morning golf League at Concord Hills. She was often found outdoors in the sun by the pool or mowing her lawn, which she kept impeccable.
