The Grand Slam Story


Jim Donnelly has been the proud owner and operator of Tennis Emporium & Grand Slam Tennis for over 42 years. Grand Slam Tennis was opened in 1986 after the birth of Jim's youngest son, Chase, who is currently his business partner. An owner can always be found in either location, as Chase operates the Commack Store and Jim, Miller Place. We are proud to be a customer-friendly store and have recently expanded our brand by opening a second location in Miller Place.
