  • "We were very pleased with our experience with Brent and Grand Slam Courts. He is very cordial, professional and punctual... all very good qualities to have in a business like this. He presented us with a variety of choices and helped select the right products and court configuration for our yard. He also assisted with navigating Home Owners' Association approval which was a big help. We could not be happier with the final product — what a transformation!"
