Meet Aaron Anderson

Board Certified Pedorthist, Founder PTI Orthotics & Foot Resource Lab

In Colorado, anyone can open an office and fabricate orthotics. Many self-proclaimed experts, which have no formal training or schooling, are now filling prescriptions for foot orthotics. It is not uncommon to have shoe stores or athletic stores have a person on staff that makes custom supports in the back room. Going this route is not ideal in any way.


Having served all of Colorado since 1991, Aaron is one of the most experienced C. Peds in the state of Colorado. Aaron served two years as an apprentice under another Board Certified Pedorthist before becoming Board Certified himself in 1993. Aaron is a graduate of Northwestern University Medical School Orthotic – Prosthetic Center with a course of study in Foot Orthotics – Prosthetics, Comprehensive Pedorthic Management of the Foot and Clinical Concepts and Fabrication Techniques. Aaron has had advanced training in CAD/CAM software and 3D design, CNC machining and advanced manufacturing methods, pediatric heel stabilizers, gait plates, pediatric and adult biomechanical theory.

He has also had advanced training in orthopedic shoe modifications and eight different intrinsic biomechanical feet orthotic posting methods. Intrinsic posting is the altering or modification of the neutral position positive foot model or neutral position 3D scan to induce a more normal muscle function, improve alignment, control abnormal motion or abnormal position of the foot and to control the abnormal motion or abnormal position of the lower extremity that is affected by the position and/or motion of the foot. After these intrinsic posting methods are applied, any material molded over the foot model will have those attributes molded directly into the orthotic itself.

Aaron has been published in O&P Edge Magazine (a national orthotic, prosthetic, pedorthic trade journal) and has been a national presenter/educator for one of the premier Orthotic, Prosthetic and Pedorthic annual conferences in the United States. He has also mentored other pedorthists from several countries.


Patients, referring physicians and consumers can rest assured that when working with PTI Orthotics & Foot Resource Lab, they are working with a trained professional that is Board Certified in pedorthics. What is pedorthics? (ped-or-thiks): The design, manufacture, fit and/or modification of foot orthotics, shoes and related devices to alleviate foot pain caused by disease, overuse or injury.


Because Aaron is Board Certified, he is required to fulfill continuing educational requirements by attending classes, seminars and symposiums, sometimes several times a year. Because of this, you as a patient or referring physician can rest assured that you are working with a true professional who is educated on the most proven methods, uses the best materials and is up to date with the latest advances in the science of pedorthics.


With his extensive experience in orthotic design, fabrication and modifications, Aaron is called upon for consultations by many medical practitioners. Aaron has designed over 20 models of foot orthotics that are unique to PTI Orthotics and is seeking patents on several of these because of their effectiveness in treating certain pathologies. He has developed many clinical solutions based on the latest concepts in bio-mechanics and superior manufacturing methods. Through PTI Orthotics, Aaron has sponsored educational events for the American Physical Therapy Association and has offered educational courses at the Colorado Physical Therapy Institute. Many sports and physical therapy clinics seek Aaron’s advice in bio-mechanical evaluations, gait analysis, casting methods and orthotic fabrication.

Aaron knows the foot orthotic and shoe business. He is a trained, second-generation professional shoe fitter and an active member of the American Board For Certification in Orthotics, Prosthetics and Pedorthics.
