North Penn Performance™ brings together medically based stretching, laser therapy education, and longevity assessment technology — all designed to help people move better, recover faster, and live longer.
Each division serves a unique purpose, but together they form a complete system for improving physical health and performance.
Clinical stretching guided by anatomy and medical science
Class IV laser therapy education and practice building
Longevity assessment app with biological age calculation
Medically Based STRETCH is a clinical approach to flexibility and mobility. Unlike general stretching you might do on your own, every protocol is grounded in medical science and delivered by trained professionals who understand anatomy, biomechanics, and how the body heals.
It helps with limited range of motion, post-surgical recovery, chronic tightness, athletic performance, and overall wellness. Many people find that adding medically based stretching to their routine helps them achieve results they could not get from exercise alone.
STRETCH sessions are hands-on, one-on-one, and tailored to each person's body and goals. Whether you are recovering from an injury, training for a sport, or simply want to move better as you age, this approach meets you where you are.

Laser Pro is our education and training platform for Class IV laser therapy. Class IV laser is an evidence-based treatment that uses focused light energy to reduce pain, decrease inflammation, and accelerate tissue healing.
It is used by physical therapists, chiropractors, and other healthcare providers to treat conditions ranging from back pain and arthritis to sports injuries and post-surgical recovery. Laser Pro provides the clinical protocols, training resources, and business strategies that practitioners need to deliver this service effectively.
Note: Laser performer requirements vary by state practice act. STRETCH can be performed by anyone, while laser may require specific licensure depending on your state.
Learn more about Laser ProLongivica Pro is a longevity assessment app that measures your strength, mobility, balance, and cardiovascular fitness through 42+ standardized clinical tests. It then calculates your Biological Age — a number that tells you how old your body is performing compared to your actual age.
Most people are surprised by their result, and that surprise becomes motivation. The app identifies your specific strengths and weaknesses and generates personalized recommendations to help you improve. Clients are drawn to improving specific metrics — like grip strength or balance — to bring their biological age closer to (or below) their actual age.
Whether you are a patient at a clinic, a gym member, or someone who simply wants to understand their physical health better, Longivica Pro gives you a clear starting point and a path forward.
