In 1986, Todd had a motorcycle accident, sustaining a spinal cord injury at the cervical 5-6 level.  Throughout and since his rehabilitation process, he experienced numerous frustrations with both the quality and functionality of equipment available for use by people dealing with a disabling condition, and began utilizing his prior knowledge of the bicycle/motorcycle industry to modify existing products, and design new products to more satisfactorily suit his need and desire to regain independence.  As his designs progressed, he experienced a local demand for some of his early products in the rehabilitation and therapy market, and thus started ADI.  This allowed and encouraged him to continue development of his engineering ideas, and led to the distribution of his products throughout the U.S. market, in rehab facilities and through medical equipment suppliers, and through a broader scope of national and international distribution. Todd also has established relationships with VA Systems providing a wide range of products, serves as an ongoing consultant to therapists and veterans regarding individual mobility needs, and works closely with the University of Pittsburgh, Human Engineering Research Laboratory, in the development of advanced wheelchair technologies and equipment.
