For nearly 50 years, Frontier Siding & Windows has been a locally owned, family-driven company dedicated to quality, craftsmanship, and customer care. What began as a small, family-run operation has grown into one of North Central Oklahoma’s most trusted names in exterior remodeling—serving homeowners and businesses with the same integrity and attention to detail that defined our start in 1976.
With showrooms, warehouses, and operations in both Ponca City and Stillwater, we proudly serve communities across North Central Oklahoma and beyond. Our team’s deep experience in installations, sales, and project management ensures that every project—large or small—is completed with professionalism, reliability, and pride in every detail.
Gary grew up on a dairy farm north of Enid, Oklahoma. He is a proud U.S. Navy veteran (1965–1968) and cultivated his interest in home improvement while working in a family business in his youth. In 1976, he founded Frontier Siding & Windows, applying his passion for hands-on work, high standards, and service to the community. Gary and his wife Nancy, raised their families in Ponca City. They have three sons: Mark, Jason and Ryan and one daughter, Ann Jackson. Gary continues playing an active role in guiding the company’s vision.
Mark brings over 30 years of experience in installation, sales, and management. His leadership centers on ensuring every customer receives a seamless experience—from estimate to installation. His eye for detail and commitment to long-term satisfaction have earned Frontier a reputation built on trust and referrals. Raised in Ponca City, Mark returned home after college with his wife, Andrea, to grow the business locally. The Ponca City community is where he and Andrea raised their two sons, Blake and Kyle.
Ryan’s involvement in the siding and window industry spans his lifetime. From learning the trade early through hands-on installation work, he now leads commercial project management to uphold Frontier’s standards of quality, craftsmanship, and customer satisfaction. Ryan and his wife, Meredith—both Ponca City natives—have been married since 2011. Together, they have two children, Thea and Coy. After several years in Stillwater, the Shepard family returned home to Ponca City in 2024, where they continue to invest in their community and family-owned business.
