Our Passion

Melissa first became interested in Human Factors Engineering after her brother sustained a spinal cord injury in 1999 while serving in the U.S. Army. Once Matt was discharged from rehabilitation and started working towards living independently, Melissa observed how challenging it can be for end users to interact with seemingly simple to very complex medical products.

Because of the challenges she saw her brother facing when designs required users to interact with confusing information or sustain impossible motions, Melissa pursued accessible design that led to human factors engineering through Universal Design. Melissa's journey is through her brother's journey.
