Ethan Ketterer
✅ Went from robotic to natural in weeks
"Once I found that natural flow of my swing, it just feels better than ever. You can consistently drive balls and not really worry when you're in the box."

Graham TooGood
✅ 30 Days — Complete Transformation
"My swing just feels so much cleaner, so much more refined. There's not a whole bunch of moving parts. I just feel athletic when I swing."
Dad: "There are certain people that need to be coaches, and to me you're one of those guys. It was well worth the money."

Ryan Foster
🔥 Almost Cut → Most Improved
"I might have gotten one or two hits all of last spring. Turning around this year, I don't think there was a game where I didn't catch a barrel."
— Travis Foster (Ryan's dad): "His approach is spot on — he tailors the program to the individual. He takes the player's natural swing and adds small, incremental tweaks to get the most out of it versus trying to rebuild the entire swing. Buy in is 100%."
JUCO

⚡ Distance PR + EV PR in One Session
"I ended up hitting a distance PR and an exit velocity PR in the same day after a 30-minute call. I've gone from a pushy, scared hitter to more confident than ever, crushing the ball to all sides of the field."

Ryan Duffy
⚾ Batting 3-4 Hole Playing Up a Level at 14
"Now that I can just trust it — I don't have to worry about it. I look confident walking into the box and they throw me curveballs. They think they can get me out with them. They can't."
— Ryan's dad: "He learned so much from Jantzen, tells me what we need to do. I do what he tells me. It's been amazing seeing the progress."

Brady Greene
⭐⭐⭐⭐⭐ Google Review | "Best My Swing Has Ever Felt"
"It took hitting from this complex 10 different steps to — all I have to think about now is hit the ball. My head is so much more calm. Some of the farthest balls I've ever hit in my life. Just constantly."
⭐⭐⭐⭐⭐ Google Review: "This guy is legit. Teaches you to find YOUR swing, not somebody else's. This is the best my swing has ever felt."
Football coach told him he had a Ken Griffey Jr. swing after 3 months.

📊 91 Max → 94 EV | +4-6 MPH Off Flips in 2 Weeks
"Before the program, pitches I could have put over the fence in left field — I'd just put up the middle because I'd never get the delivery of the barrel. Now I can tell when I'm not delivering it, and I know exactly how to fix it. There are unlocks still coming."

✅ Online Setup — Perfect for College Athletes
"It's not just drills. We talk through my approach, my swing thoughts, and the mental side of hitting. The podcast-style Zoom calls with pro players and coaches have been unreal — hearing what it actually takes to reach the next level has been eye-opening. Witte's experience shows in everything he does."

✅ 10 Years of Development
"Jantzen has been a mainstay in my son's development for the past 10 years. He keeps it simple, to the point, and fun — and the improvement both from the swing but more importantly the mindset of hitting has been amazing. Highly recommend on all fronts."
