Al Herringshaw of Pella says they have been in business since 1962. “We are best known for providing the highest quality and most innovative windows and doors in the Valley,” he says. “We are also known for providing an outstanding customer experience based on value, customer care, and our limited lifetime warranty.” According to Herringshaw, the secret to Pella’s success is that the staff “thinks windows and doors” 24 hours a day. “It ’s all we do,” he says. He loves the Valley because of its people. “They want good value and to be treated with respect,” he says. “We are great at both of these.”
