Engineering that breaks down barriers

Tetra Ryerson is a student run group that works with the North American Society of Tetra. Together we create assistive devices for individuals with disabilities





Josh brings 17 years of product development experience to Synaptive Medical where he leads a team of over 100 engineers and has overseen the development and launch of 11 major products. Before joining Synaptive, Josh was director of engineering for Hologic’s MR division; there, he charted the product roadmap for MR coils used for breast and prostate cancer imaging, which were acquired through Hologic’s acquisition of Sentinelle Medical Inc. Prior to Sentinelle’s acquisition, Josh brought nine breast coils to market for Siemens and Toshiba magnets in his role as systems engineer and technical product manager. Outside the medical device space, Josh spent six years at McDonalds, Dettwiler, and Associates as a software and systems engineer on the ROSA and Orbital Express autonomous satellite servicing programs. He holds a Bachelor of Applied Science degree in Systems Design Engineering from University of Waterloo and a Master of Science degree in Computer Science, specializing in reality-based modeling and computational intelligence, from the University of British Columbia. Josh is a licensed professional engineer and actively volunteers through the Professional Engineers Ontario’s Engineer-in-Residence program.




Luke’s Story:
It’s 2002, the world’s first camera phone had hit the market and Nickelback’s How You Remind Me (*shiver*) is getting major airplay on the radio. A recent university graduate named Luke Anderson has followed his dream west, and is living in the mountains of British Columbia. He’s putting his engineering degree to good use working as a homebuilder, and playing hard with other like-minded mountain biking enthusiasts.

One beautiful autumn day, Luke and his good friend Johnny were riding a tricky trail they had heard other mountain bikers rave about. They came upon a 25-foot gap jump; the stuff mountain biking legends are made of. Johnny went first and cleared it. Luke was excited to make the jump and high five Johnny on the other side. He made sure he was in the right gear, gripped his handlebars tightly, pushed down hard on the pedals, left the takeoff platform… and left his life as he knew it.

Upon impact Luke sustained a high-level spinal cord injury, and instantly found himself living in a world not well designed for someone who gets around using a wheelchair, where a single step is as large a barrier as a flight of stairs.

How It All Started:
Luke became all too familiar with encountering barriers in the built environment and this became a growing source of frustration. Talking with others including good friend and co-founder Michael Hopkins, they realized this was a citywide access issue that needed to be addressed for people of all abilities. This got them thinking, and in the fall of 2011 the first ramp landed in front of a Toronto shop owner’s stepped entryway, brightly painted and emblazoned with the now iconic STOPGAP.CA stencil.
