Years before founding iFIT, Timothy R. Dillingham, MD, MS, served in the US Army during the Persian Gulf War and as a National Institutes of Health (NIH) investigator, studying the needs of patients with limb loss. And while directing the prosthetic and orthotic clinic at Johns Hopkins University, he was amazed at the time and effort invested trying to make a hard socket fit a changing limb. Putting his engineering background and industrial manufacturing know-how into practice, he envisioned a prosthetic that could better adjust to individuals’ needs, thereby increasing use and boosting satisfaction.

Dr. Dillingham founded iFIT Prosthetics LLC® to advance the science of lower limb prostheses, and is especially grateful for the following partnerships:

• NIH offered valuable funding and insights to realize this vision of a self-contained, immediately fit, adjustable, transtibial prosthetic.
• Advanced Design Concepts, Inc., provided critical engineering support for this project from the very beginning, from designs to analyses to prototyping. Special thanks to Jim Marschalek, MS, lead engineer and Mark Schaefer,  MS, ACD President.

iFIT Prosthetics is a veteran-owned American business proudly making products in Milwaukee, WI.

Our partner, Advanced Design Concepts, Inc. provides the engineering support for this project. ADC has been with us since the beginning and served as our engineering team, providing the designs, analyses, and rapid prototyping necessary to develop these products.  Jim Marschalek, MS is the lead engineer who helped propel this project forward.  Mark Schaefer MS, President of ADC, collaborated throughout the evolution of our product.
