First Pools USA is a McAllen-based pool supply business founded by Jay Carlsen, built to serve both local homeowners and commercial businesses across the Rio Grande Valley and customers nationwide through e-commerce. What began as a digital storefront has grown into a trusted source for pool equipment, maintenance supplies, and expert guidance, helping customers keep their pools safe, clean, and operational year-round. With a strong focus on accessibility and reliability, First Pools USA has become a go-to resource for both everyday pool owners and commercial businesses.
As demand for his products continued to grow, Jay set his sights on expanding into a physical retail presence. After connecting with PeopleFund through the SBA Post-Loan program, he gained access to the capital and support needed to scale his operations. That support helped him reach a major milestone: opening a brick-and-mortar pool supply store in McAllen, strengthening his ability to serve the entire RGV region while continuing to fulfill orders nationwide. Today, First Pools USA reflects Jay’s persistence and vision, bridging online convenience with in-person service, creating local jobs, and expanding access to quality pool supplies across South Texas and beyond.
