Collier O and P Specialties

Collier Orthotics and Prosthetics, formerly Collier Rehabilitation, has five areas of specialization: Patient Care, Upper Extremity Prosthetics, Pediatric Care, Knee & Sports Orthoses and a bilingual Prosthetic Practitioner.

Patient Care is our first priority.

Collier patient outcomesCollier’s patient care is directed by experienced and dedicated practitioners in their respective fields of practice making them expert providers. This ensures that each patient receives the most appropriate device by practitioners who specialize in their scope of practice. This specialization includes pediatric and upper extremity prosthetics by practitioners with over 20 years of experience.


At Collier Orthotics and Prosthetics our first priority is patient care. We accomplish this by spending time listening to our patients and their particular needs in order to provide the most appropriate care. Each patient is unique and they are treated as whole individuals regardless of their limb absence or orthotic need.


Our certified and licensed practitioners are educated about all levels of products, and have the knowledge and experience to provide device training for high-level devices. Their many years of experience is a resource for their patients. We work as a team with other providers so our patients will benefit with successful outcomes.


Our practitioners are by your side to help you get the correct device for your lifestyle, needs and goals. If you are struggling, you can call on us. Our Director of Prosthetics holds a degree in psychology, which gives him a better insight to care for patients with limb loss — and he is a terrific listener. Each patient is unique and they deserve to be treated as whole individual who has self-worth.

Pediatric Care Specialists
