After becoming an ABC certified prosthetist/orthotist more than 25 years ago, Jennifer began her professional journey by providing acute, rehabilitative, and long- term care for patients ranging from pediatric to geriatric. Jennifer then transitioned to the development and education sector of the prosthetic manufacturing industry.  Her experience on the industrial side of prosthetics has included the design, development, and testing of CAD/CAM technology, socket design, and suspension. For the past several years Jennifer has focused specifically in the application of computer-aided shape acquisition techniques with regards to socket and brace design. Her goal is to improve patient outcomes through the development of news ways to achieve a comfortable prosthesis or orthosis and provide more effective tools for fellow clinicians.
