welcome to FUNCTIONAL PRECISION

Where science, movement, and athletic potential connect.

“At Functional Precision, we believe that every elite athlete is built, not born. Our mission is to empower the next generation of student athletes by refining their movement patterns and engineering a foundation of excellence that translates from our lab to the field of play.”

“Founded by Dr. Rettig, a board-certified specialist in both Pediatrics and Sports Medicine, Functional Precision was born out of a unique understanding of how young bodies grow, move, and excel. We don’t just look at how an athlete plays; we look at how they move. By applying a developmental lens to performance training, we help athletes tune their bodies to move with maximum efficiency and minimum waste.”

Our Philosophy

Move Better to Perform Better

Whether you are a middle schooler finding your footing, a high school standout, collegiate or recreational athlete looking for that competitive edge, our approach remains the same: Performance Refined. We treat every athlete like a high-performance machine that requires precise calibration.

  1. Biomechanical Efficiency: Optimizing how the body moves to generate power.
  2. Athletic Maturity: Teaching young athletes the “why” behind their training.
  3. Engineered Excellence: Using science-backed methods to elevate your game.

We Fine-Tune the Machine

We analyze movement inefficiencies, correct them, and rebuild your mechanics for maximum power, efficiency, and consistency.

The Performance Perception Layer

Most Athletes Are
Working Hard But Not
Always Working Efficiently.

Vision drives timing, reaction, and decision-making. We assess how quickly and accurately athletes process visual information under game conditions.

FUNCTIONAL PRECISION

Functional Precision offers a proprietary, data-driven assessment that reveals how an athlete’s movement patterns impact performance. We provide a clear, actionable roadmap to enhance efficiency, power, and overall athletic potential.

Working with Functional Precision completely changed how I understand my swing. I always thought I just needed more strength, but the analysis showed me it was actually my movement patterns holding me back. Everything finally clicked.

I had never seen my mechanics broken down like this before. The 2D and movement analysis showed things I was completely unaware of. My consistency and power improved within weeks.

I always struggled with my serve consistency. After the assessment, I realized my mobility and sequencing were the issue. The clarity I got from Functional Precision was unlike anything I’ve experienced in training.
