I highly recommend National Pools & Spas and Dan Katzman. From our first meeting in January, Dan impressed me with his expertise and personable approach, highlighting important details others missed. He ensured everything was completed on time and as promised, including the pool vacuum he promised. Despite some minor contract issues, Dan and his team resolved everything promptly. My pool was installed in two months, passing all inspections on schedule. Special thanks to Jaime Bojanowski and the service department for their excellent support. Dan and National Pools & Spas exceeded all my expectations!
