Testimonials


Through multi-extensive throwing programs, pre and post workout arm care conditioning, off-season intensity workouts, and the mental aspects of the position, Coach Gunderson has been instrumental in my son’s successful and healthy development as a pitcher.


Kevin Gunderson has been working with our son for the last 4 plus years, we couldn’t have asked for a better coach. Kevin has been instrumental in developing our son into the pitcher he is today. Kevin works hard to ensure proper techniques are being taught and used. We have seen Kevin’s business explode with success and are thankful for his guidance moving forward.


Hi Kevin,

Wanted to send you a note to say thanks to you, El, Gehrig, Brett, and the entire 503 staff for your commitment to teaching the game of baseball. It’s been a year since Aiden started coming to you for arm care and pitching lessons, and we also moved our hitting instruction to 503 this fall.

The difference your team has made in Aiden’s baseball skill set and mental IQ is amazing. He now understands the “fundamentals” of the swing and how to be more efficient with his throwing motion while creating more velocity. Additionally, your staff holds him accountable and they don’t assume he will remember everything during the lesson. All the 503 instructors “break it down” so that Aiden truly understands what he is learning during instruction. The drills the team gives us are practical and easy to do at home. We also tried athlete builder with your recommendation. After 8 weeks, Aiden has lost 20 pounds. It’s remarkable how much quicker he is than when he started and has also given him more focus.

There is no doubt Aiden is more prepared than ever to start the 2017 season. Wishing you and the team at 503 continued success!

Best regards,

Brad Kehm
