Hi, I’m Joseph Benedetto, the founder of Cincy Sports Nation. If there’s one thing that sports have taught me over the years, it’s that the field can teach you just as much about life as any classroom. Back in 2017, when the opportunity came to breathe new life into an old tire distribution center in Milford, Ohio, I knew it had the potential to become something more than just another building. I wanted to create a space where players of all ages could come together to train, to compete, to connect and that’s exactly how Cincy Sports Nation began.

It quickly became clear, though, that the real magic wasn’t just in the games themselves. It was in the moments between them the coaching advice passed down after practice, the skills quietly honed, the lessons that athletes carried with them long after they left the field.

This isn’t a collection of theories or textbook strategies. It’s built from real hours spent running drills, adjusting techniques, and learning lessons the hard way. At Cincy Sports Nation, our goal is simple: to pass on that knowledge in a way that’s honest, accessible, and built for anyone who’s serious about getting better, no matter their starting point.

Thanks for being part of this journey. Even though the setting has changed, the mission remains the same helping athletes grow smarter, stronger, and more passionate about the games they play.
