★ 5★ 4★ 3★ 2★ 1Trying to find a kids sports trainer is hard. I was so lucky to find Billy - not only is he affordable for multiple kids but he is the best sports trainer around! My kids skills and confidence improved and upped their physical competative level. Your kids will also be joining a community family, learn life skills and have a mentor that pushes and challenges them! You won’t regret joining the Grindathon family!
July 15 · kailee fitchMy son had trained with Coach Billy from the start of his football career from Pop Warner to High school. I am one of many witnesses that have watched Coach Billy’s program grow from training at the city parks to creating a great facility in Bellflower. His hardwork and dedication built the Grindathon corporation having a phenomenal team of coaches that have worked with my son as well. Coach Billy and his team will not only physically train with their clients, but will mentor them to become a great athlete. Even though he has a very busy schedule, Coach Billy will find time to come and watch a game. We feel that we have joined the Grindathon family for life. Thank you for always supporting Titus’s football journey.
September 26 · Charife CarrilloGrindathon will check off all your boxes when looking for an athletic training facility. It's a program where Coach Billy and the rest of the team will develop your child into a CONFIDENT athlete. The coaches doesn't waste anytime and always has an agenda for the day.My son, Rilee has been going to Grindathon since August of 2024, and there has been so much progression. He is faster, stronger, confident, and is more determined than ever. Rilee is a really shy kid that keeps to himself, but having group sessions with other kids allowed him to interact with others. He started in group sessions, moved to semi-private, and is currently doing private sessions with Coach Billy (skills) and Coach Aery (speed).As a parent of a young athlete, you will come across a lot of programs, some better than others depending on what you are looking for as a result. My reasoning for joining and staying with the Grindathon family starts at the top, Coach Billy. He is fully committed to every athlete that comes through his doors. There will not be a day where he doesn't give 100% effort into your athlete, which I feel in return, the athlete gives back. He really establishes a great relationship with the athlete, learns their strengths and weaknesses and works with them on it. This goes with all the coaches with the Grindathon family, Coach Aery and Coach Brandon.If you are looking for a performance facility, come check them out. Ask your athlete what they think of the program and you'll see what I am talking about.Thank you Grindathon Family for everything that you do and have done for Rilee. This is the culture you want your athlete in, understanding the goal, and letting the marathon continue.
July 27 · monyfool13Amazing facility. Great Coaches with high energy. Any kids in Youth Sports will find a second home here. My son has for the last 3 years and we are truly blessed having been a part of the Grindathon experience.
July 14 · Mark DaoGrindathon has truly been a game-changer for my son. From the moment he joined, it was clear that this is more than just a place to train — it's a community, a family. The level of dedication, expertise, and personal care from Billy and the entire staff is unmatched. They’ve not only helped my son improve his skills and fitness, but they’ve also instilled in him a sense of discipline, confidence, and teamwork that extends far beyond the field.The workouts are intense, but they’re also structured in a way that builds character and encourages growth. Every session pushes my son to his limits while making sure he enjoys the process. It's evident that Billy and his team genuinely care about each athlete's development, not just physically, but also mentally and emotionally.What sets Grindathon apart is the genuine camaraderie and family-like atmosphere. It's a place where everyone is cheering for each other, and that positive energy is contagious. My son feels supported, motivated, and inspired to be his best version — on and off the field.If you're looking for a place that will not only make your child better at sports but also teach them life lessons, Grindathon is the place to be. Billy and the staff are the best, and I can’t recommend this program enough!
