About Us


Protocol Builder was created to save clinicians time, and to assist in eliminating the need for individual protocols for each condition they wish to treat using laser therapy. You will still need to be competent in the use of your laser device, and will also need your assessment skills and clinical confidence to know when to move to the next step in the process, but this tool can assist with helping clinicians make good treatment decisions when using laser therapy.

Keep in mind laser therapy is a modality and is best used to complement and be used in conjunction with other therapy such as: traction, massage, manipulation, adjustment, mobilization, physical therapy exercise, taping, bracing and others, and generally is not meant to be a solitary means of treatment.

Protocol Builder

Over the past few years we’ve been diligently writing individual protocols and producing videos to bring you the most comprehensive offering of laser therapy treatment through Laser Therapy U. Now we are offering this new tool based on the Priority Principle treatment pathways, created to help you navigate your way through this process. Instead of referring to an individual written protocol, Protocol Builder will walk you through a treatment pathway by asking questions along the way to guide you through the Priority Principle sequence, thus hopefully educating while eliminating the need for individual protocols within the musculoskeletal system.

Welcome to Protocol Builder, we hope you find this a valuable resource in your education and application of low level laser therapy.

Priority Principle

The Priority Principle is a dynamic methodology, used for integrating photobiomodulation methods into clinical practice, by prioritizing the current physiological needs of the patient, and then applying the appropriate sequence of treatment techniques to maximize a phototherapeutic response.

Meet Our Experts


Years ago the guidance for the therapeutic laser community was generally being led by The World Association of Light Therapy (WALT) and the North American Association for Photobiomodualtion Therapy (NAALT). Our leaders felt there was something missing as a clinical component and a sort of disconnect between the research being conducted and the actual therapy being practiced. This led to the concept of an education portal that could bridge that gap so clinicians had a resource to help them in this process.

Let’s meet some of our clinical experts that recognized the need and had the vision to establish Laser Therapy University as that portal, and the development of the Priority Principle for treatment with laser therapy.
