A decade of developing young players
Andrew brings more than ten years of coaching and a lifetime around the game — a former player at Pattonville High School, Legion Baseball, and St. Louis Community College–Meramec who has helped build programs and develop athletes across hitting and pitching.
He's a USA Baseball coach — including coaching at the SLBBA USA international games in Japan — and the head coach of the 13U Prospects, with a track record of developing youth athletes.
The reviews say the rest: a kids-first mentality, high-level training inside an encouraging environment, and — from a coach whose staff he worked with — “a huge part of my team's success this past season.”
How Andrew develops an arm and a bat
Confidence, fundamentals, work habits, opportunity — in that order. The measurement exists so a young athlete can see themselves getting better.
The delivery on video, frame by frame
Arm slot, hips-to-shoulders sequence, a front leg that holds — the pitching checkpoints, checked on slow-motion film with strike-throwing and arm-care work built around them.
Hitting fundamentals that stick
Mechanics broken down and rebuilt little by little — steady development over drastic overhauls, which is exactly how parents describe his work.
A plan a kid can follow
Written evaluation, free 4-week program, and a re-test — with the athlete understanding every piece of it, not just doing it.

From day one, it was completely obvious that Andrew operates with a “kids-first” mentality. He has a gift for balancing high-level athletic training with a supportive, encouraging, and trusting environment where ballplayers truly learn and thrive. If you get the opportunity to have Coach Andrew work with your child, jump on it.

Where and when are lessons?
Center STL — 6727 Langley Ave, St. Louis, MO 63123. Lessons run Monday – Friday · 3:00 PM – 8:00 PM.
What happens at the first session?
The assessment: a movement pattern screen, athletic testing, and your athlete's swing or delivery on film. You get a written evaluation and a free 4-week program built from it — then re-tests measure the progress against that baseline.
What's the biomechanics screening?
An add-on to any assessment (+$75): your athlete's swing or delivery slowed down and broken down frame by frame, joint by joint, against the checkpoints we coach — so the plan fixes the cause, not the symptom.
What ages does Andrew work with?
M4P trains athletes roughly ages 5–22. Andrew's track record is in youth development — he's the 13U Prospects head coach — and he works with high school arms and bats as well.
