★★★★★Joseph EspositoI would like to thank the Diamond Zone team led by owner Brett, for helping my 11 year old daughter with her catching position. She went from being a good Rec catcher to an absolute beast behind the plate.She has incorporated everything she learned from her coaches from DZ to be a strong and confident player all around. She put in the work and they were there every step of the way. Thank you DZ for the dedication from all the staff to make these kids dreams come true. What a great program for all Athletic levels, from new players to high school. My wife and I are truly happy with the results of our daughters progress over the last year and half. Thanks Brett and Staff. Joe Esposito..
★★★★★Antonia AbbenanteBrett is amazing! My daughter goes to him for catching lessons and we couldn't be more pleased with our decision. In just one lesson you could see the difference. She truly enjoys going to him. He does so much and is so involved( Being the owner, giving private lessons, teaching classes and coaching travel teams) regardless to how busy he is he will always makes time for us. He is very accommodating and a fair and honest person. You will not be disappointed. He truly cares about the kids and giving them the right tools to be successful!
★★★★★Christopher CretellaOur first season with DZ. Awesome experience. Pete was an awesome coach. My son also recieved great instruction from Brett and Tim. Can't wait for spring season.
★★★★★Melissa MartineauThe staff at DiamondZone is amazing. They teach athletes both general skills and position-targeted skills. They care about player development, and emphasize sportsmanship, respect, and hard work. Every athlete, regardless of level of ability, WILL benefit from clinics and/or private or group lessons. My boys have very different personalities, learning styles, and levels of confidence. Both have learned game changing skills. Staff members are excellent at addressing the varying needs of the athletes. Athletes do drills and learn techniques that are used by players in the MLB. I strongly recommend checking DiamondZone out. You will not find a higher quality sports training facility and staff!
★★★★★Matt McCulloughWe had my son's 8th birthday party here in October. It was easy to plan and set up, and they made everything super easy. We did dodge ball and the kids just wnerally went nuts running around having a good time. It's a good size for birthday parties, and the people were great.
