About Us

For 18 years the name Prosthetic Design Inc. has stood for Cad-Cam integration through modular parts and production materials. With a work smarter, time efficacy spirit, and a creative, well developed entrepreneurial skill set, Tracy Slemker founded Prosthetic Design Inc.

In 1991 with Cad-Cam firmly entrenched in main stream industry the orthotic and prosthetic industry was slowly moving into the first of many software and hardware elements made specifically for the prosthetic industry. At the same time funding and reimbursements were and are consistently declining for custom made artificial limbs. What once was an artesian craft is consistently moving into an engineering science. Tracy Slemker saw the need for components that enhanced the use of Cad-Cam allowing increased modularity and adjustability maintaining a predictable low profile attachment and suspension. Today PDI is located in Clayton Ohio and continues to develop and refine the process of prosthetic manufacture, assembly, and adjustability for the clinician, technician, and patient.
