In 1975, she was selling custom-built homes and Ken was a roofing contractor. They married and became Business partners. In 1982, they used their lines of credit to secure a loan that enabled them to establish ABC Supply. ABC Supply is privately held, and sells roofing, windows, gutters, and siding for residential and commercial buildings.
