★★★★★Bryan CarterScott Cooper is a great hitting coach. He has done a great job working with my son and improving his performance at the plate. Last night as we were heading in for his session, my son told me that this was his favorite time of the week.
★★★★★Marc MacellaioMachOne has been a great experience. Very well run, with lots of information and feedback for my son on how to improve. The combination of pitching technique and weight training in one session has given more purpose for each visit.
★★★★★Ryan BraunGreat training and instruction. They provide a lot of drills to work on at home and engage with our son each visit asking what has been working, what feels right or off and seem to adjust to that. Our son’s confidence quickly came back after working with the trainers here.
★★★★★John MazzolaI’ve known Matt, Bascha and the entire AllStar team for at least 10 years. I held our team’s winter workouts there for years until our team joined the club scene. Never crafted a review for them and I don’t know why. My son recently wrapped up his “youth career” and I figured what better time to write a review than now. As I reflect on the amazing baseball journey I’ve taken with my son. This is an awesome facility with great people and instructors. Great cages and turf space to conduct all of your workouts. As my son was approaching his senior year in high school, we felt he was leaving a little pitching velocity on the table (he’s a big kid). We looked into the Mach Pitching program and could not have been more pleased. Andy and team helped him capture 3 mph merely by tweaking some of his bad habits that developed over time. The effort is the same but more velocity with efficient mechanics. My son is playing ball in college and he’s asked if he can continue to work the Mach program until he reports to school. He knows this team will ensure that he is ready for day 1 when he steps on campus. Anytime I have conversations regarding baseball training programs or facilities, I mention this place. Top notch and would absolutely trust the baseball health and safety of my boy with these guys and gals all over again. What a ride!
★★★★★Focal ImagingMy 9 y/o son attended a one day camp on Presidents’ Day. He had a lot of fun at the camp and enjoyed learning from college players hitting and fielding techniques. He also said being in a small group with an instructor was really nice. Our first time here but we thought it was a great facility and the staff was very friendly.
