Miller Prosthetics & Orthotics, LLC provides prosthetic and orthotic services in Belpre, Ohio and Parkersburg, WV. We provide high tech solutions for the best fit and service for all patients. All prosthetic patients are welcome, including below and above knee, foot and upper extremity amputees. Orthotics includes custom fitting and fabrication of arch supports, ankle-foot orthoses, knee braces and back braces to eliminate pain and assist during the healing process, while adding stability when walking or moving. We strive to return patients back to the activity level they desire from walking and moving to running, fishing and hunting.

Owners Mark and Nancy Miller bring together best practices for both the clinical and business side of Miller Prosthetics & Orthotics.  In addition to precision measurements, custom fitting and finding the prosthetic or orthotic solution for you, we address the emotional side of limb loss.  The Miller’s founded and host the Prosthetic Users Group to enable new and experienced amputees to meet, to be inspired by each other, and to help each other adapt to life with limb loss.
