Clinical Staff

We are proud of our expert professional staff at Dankmeyer Inc., who form a part of your multidisciplinary team.  Whether you are our patient, or refer a patient to Dankmeyer, you can rely on a combined 175 years of professional practice and dedication to patient care and service.  Our Certified Prosthetists and Orthotists have been educated at a number of fine institutions across the United States, but are all essentially home-grown! As children, some aspired to be artists, dancers, musicians, professional athletes, engineers and teachers.  Ultimately, they were led to Prosthetics and Orthotics by their combined passion for hand skills, solving complex problems and a desire to enhance people's lives through the use of well designed and crafted prostheses and orthoses.

Our mission is to offer comprehensive and custom prosthetic and/or orthotic solutions for improving each patient's ability to function at home and in the community.  

Here are some things you might not know about our clinical staff.
