Aj is best known for designing systems that produce measurable results in the HLP Technique for improved swing mechanics, bat speed, exit velocity, throwing velocity, and overall athletic performance. His frameworks blend biomechanics, special strength training, and skill-specific development into repeatable, high-impact training models used by athletes and coaches across the country.

He holds certifications including the CSCS (Certified Strength and Conditioning Specialist), Westside Barbell Special Strength Certification, Driveline Baseball’s Foundations of Pitching Certification, and is a Certified HLP Instructor. He is also a Functional Range Conditioning Mobility Specialist (FRCms) and Functional Range Strength Coach (FRSC), specializing in advanced joint control and tissue resilience.

Aj’s coaching journey began after a frustrating college baseball career and a short stint in professional independent baseball. Determined to understand why he — and so many others — underperformed despite their work ethic, he devoted himself to studying what actually drives elite development. That obsession led to the systems OPP is now known for.

Today, Aj leads OPP with a relentless focus on athlete outcomes — combining hitting instruction, strength & power development, throwing progressions, and mobility training into one unified system. His mission reflects that of OPP: to make an impact at the highest level by equipping athletes and coaches with the systems, structure, and support they need to succeed.

At OPP, Kaleb provides personalized meal planning and nutritional guidance tailored to each athlete’s goals and training demands. By combining his insight with our strength development systems, Kaleb has helped elevate athlete performance across the board — providing the edge our athletes need to compete at their highest level.

Kaleb has served as a strength consultant for both Yakima Valley and Skagit Valley collegiate baseball programs. His experience also includes internships with Sterling College and Sterling Physical Therapy, where he gained valuable insight into athletic performance, recovery, and injury prevention.

In addition to his work at OPP, Kaleb has successfully run his own nutrition coaching business, helping countless clients transform their health, performance, and lifestyle through sustainable, evidence-based practices.
