The Family Business

Gary Shepard started Frontier Siding & Window in 1976 after he noticed a need for an exterior home improvement company in the Ponca City area. He brought with him years of knowledge and experience which he gained while working in a family business in Enid, Oklahoma. Now, after more than 35 years, Frontier Siding and Window remains a family business, owned and managed by Gary and his three sons, Mark, Jason, and Ryan. Frontier has grown into the largest exterior remodeler in North Central Oklahoma with offices, showrooms, and warehouses in both Ponca City and Stillwater.
