★★★★★Javier AlvarezGreat experience at Grand Slam USA top-tier facility with a professional environment. It was truly a privilege to have a pitching lesson with John Stuper. His knowledge, and ability to communicate adjustments made a huge impact. Highly recommend for anyone serious about developing their game.
★★★★★François GagnonDuring our vacation in St. Petersburg, we decided to stop by Grand Slam USA for some pitching and hitting sessions, for our 11yo son—and it turned out to be one of the highlights of our trip. Coaches Brian and Steve were absolutely fantastic. They were welcoming, knowledgeable, and incredibly encouraging throughout the sessions. Their passion for the game really shows, and they created an environment that was both fun and focused. The training was excellent and well structured, and we left feeling like he had genuinely improved his skills. Even more importantly, we left with great memories and a even more excitement for the game. By the end of the vacation, the only question left was when we would be coming back to train at Grand Slam again. If you're in the St. Petersburg area and looking for quality baseball training with amazing coaches, this is definitely the place to go!
★★★★★Lindsey SykesHad our son’s birthday party here and it was a fantastic experience, from the communication throughout the planning process to the set up and execution upon arrival. We were blown away. It’s a great opportunity to get kids and parents engaged in the activities and fun for most ages. The party room was perfect- clean and inviting with coolers and ice on hand. Couldn’t have asked for more!
★★★★★Joe McGeehanGreat place! Top notch instruction from some amazing coaches. We threw a Birthday party here that was so much fun! Great for all ages and the owners are very involved. Truly an amazing place to hang out and have fun.
★★★★★Bryan GallowayWe were here on vacation and my son needed a place to throw a bull pen. This is an awesome facility great mounds, has a plyo wall he was able to get his work in. The owner even gave him a few pointers while he was throwing. Greatly appreciated the friendly service and fantastic facility. Had multiple batting cages as well. Definitely recommend Grand slam if you need a place to train. We will be back on our next trip to St. Pete.
