SixFour3 supports an independent network of high-quality softball trainers. All trainers accepted into the SixFour3 network must pass a baseline set of requirements demonstrating their experience and ability as a trainer. Although we provide a a common set of core principles, we allow all of our trainers to teach their own unique style. Our goal is to offer a broad set of trainer skills and personalities that best align to the individual expectations of each of our members.

With any SixFour3 membership, you will have access to any/all of our trainers, so feel free to give them all a spin to make sure you find the right one for you.
