Provenir Institute is the development company behind the Florida Stormers — and open to every athlete who wants their progress measured, not assumed. We test it, coach it, and put it on paper.
Most training tells you to "just keep working." Provenir starts with a number, builds a plan around it, and proves the change. Every athlete gets a baseline, a target, and a retest — so progress is a fact, not a feeling.
Baseline testing captures where you actually are — velo, exit speed, sprint, mechanics — before a single drill.
Pro video breakdown finds the movement patterns invisible at full speed, then targets them with a drill progression.
You retest. The report card shows what moved. That's the difference between training and development.
Each program stands alone or stacks into a full development plan. Roster families train inside it year-round; outside athletes can book any piece.
A pro reviews your hitting or pitching frame by frame, identifies the patterns you can't see at speed, and returns targeted drill progressions with a plan.
1:1 instruction with a professional coach — hitting, pitching, or fielding — built around your evaluation, not a generic script.
Group development sessions that bring the Provenir method to a full roster or an open enrollment — measured, coached, competitive.
Arm health and velocity development built on Shea's MLB experience with developing arms — a program to protect and build the throwing athlete.
Baseline plus retest — exit velo, throwing velo, sprint speed, mechanical evaluation — and an individualized development plan. The measurement spine of everything we do.
Florida Stormers families get member access to Provenir — breakdowns, testing, and development resources included as part of the program.
The same loop the Institute runs for every athlete. It's simple on purpose — because a system you can measure is a system you can trust.
We capture your starting numbers and record mechanics on video. Nothing is assumed.
Your breakdown becomes targeted drills and an arm-care or hitting progression with clear goals.
After the work, the same tests run again — under the same conditions — to isolate real change.
You leave with paper: what moved, what's next, and the number to beat.
Provenir's instruction is led by Shea Spitzbarth, a former Major League pitcher who brings pro-level standards to developing athletes. The same coach behind the Florida Stormers, Shea built the Institute's arm-care and evaluation approach on what actually holds up at the highest level.
The result is coaching that treats young athletes like the developing professionals they could become — measured, patient, and honest about the work.
Provenir is the development engine. The Florida Stormers are its flagship competitive program — and the first place the method shows up on the field.
Our competitive travel program — a program of Provenir Institute — where the testing, breakdowns, and arm-care plans meet real games. Roster families train inside the full Provenir method year-round.
