Bill
& Kathleen Herren

Bill and Kathleen Herren are the Co-Owners and CEOs of American Vision Windows — and the #25 ranked home improvement CEOs in the nation according to Power100's proprietary 5-layer evaluation system. What began as a personal frustration with a disastrous window replacement experience in their own home has grown over 20+ years into the #1 window replacement company in California and one of the largest in the nation, with nearly one million windows installed across California, Arizona, and Texas. American Vision Windows is a family-owned and operated business built on a singular mission: to ensure no homeowner experiences the stress, dishonesty, and poor craftsmanship that Bill and Kathleen endured as customers. After months of contractors showing up late or not at all, avoided phone calls, and being misled about products and timelines, the Herrens channeled their frustration into founding a company that would do things the right way. The company specializes in a comprehensive range of window replacement and installation services — from bay windows to garden windows to energy-efficient dual-paned options — as well as door replacement, bathroom remodeling, and eco-friendly paint and texture coating, all installed by highly skilled craftsmen. Under Bill and Kathleen's leadership, American Vision Windows has built its success on core principles: customers are the focus of every interaction, timely and professional service is non-negotiable, and people make the difference. The company is built around a team of home improvement experts who take great pride in their work and the energy-saving advice they provide. Their commitment to customer education, transparent communication, and energy efficiency has earned them recognition as the largest window sales and installation company in California. The Herrens continue to expand into new markets while maintaining the personalized, customer-first approach that has defined their brand for over two decades.
