when William and Anne Lee Willet founded their stained glass and decorating company in Pittsburgh, Pennsylvania. In 1977, the company merged with James Hauser’s glass company in Winona, Minnesota, creating one of the world’s largest stained glass studios. After 37 years and thousands of stunning works, the Phillips family purchased the company, bringing renewed energy to its legacy. In 2023, 125 years after its founding, Aspen Mountain Partners returned the company to its original name—Willet Stained Glass Studios. Today, our windows grace churches and historic buildings across all 50 states and 14 countries, including landmarks like the National Cathedral in D.C. and Grace Cathedral in San Francisco.
