Amanda Boxtel
Founder & Executive Director
Since February 27, 1992, former Brisbane-ite Amanda Boxtel has dreamed of walking again. On that fateful date, a freak skiing accident in Aspen-Snowmass, Colorado rendered her with a permanent spinal cord injury from the pelvis down. She has since been involved in community and outreach projects that aim to improve the lives of individuals with disabilities in the United States. Amanda is the founding Executive Director for the Bridging Bionics Foundation, demonstrating how ongoing physical therapy and bionic exoskeleton technology has a positive impact on quality of life. Amanda showcased the first partially 3D-printed exoskeleton in the world for Singularity University’s European Summit in Budapest, Hungary, and then again at the Aspen Ideas Festival in Colorado. In November 2014 Amanda presented her forwarding thinking ideas about neuro-rehabilitation and humanizing technology at TEDCity2.0 in Chengdu, China.
Amanda was the first person in the United States to own an Ekso TM bionic exoskeleton suit manufactured by Ekso Bionics, which she acquired in June 2013. She donated her exoskeleton to the Bridging Bionics Foundation for use in the Roaring Fork Valley Community to help others who are paralyzed walk. She has walked in four bionic exoskeleton suits from different manufacturers around the world including Ekso, ReWalk, Indego, and a prototype from Bionik Labs in Canada.
Amanda lives with her golden retriever, Winston, in Basalt near Aspen, Colorado.

Julia Tallmadge

I grew up in Carbondale and have always had a deep appreciation for the outdoors. After graduating from the University of Puget Sound in 2006, I spent several years traveling, which ultimately led me back home to the Roaring Fork Valley. Here, I’ve continued to enjoy outdoor adventures with my family and friends.
Professionally, I’ve explored various roles that have helped me identify my strengths and weaknesses, particularly honing my keen eye for detail. I am excited about applying these skills for Bridging Bionics which significantly impacts people’s ability to use their physical bodies—a capability I have always valued.
