Penta was founded by university students in 2015 to bring high quality, low cost prosthetic care to Vietnam while repurposing what would otherwise be medical waste in the United States.

The idea came out of the realization that 95% of amputees in Vietnam lack proper prosthetic care while thousands of functional but slightly outdated prostheses are being replaced in the United States every year.

We at Penta found that we could resolve these two problems by collecting and repurposing used prosthetic equipment in the United States. In doing so, we would be able to clear the clutter out of private homes, relieve clinics of the responsibility of collecting unusable devices, and also bring the ability to walk, work, and learn back to amputees in Vietnam.

Impact (2019)

Penta’s mission is impact-driven and our team closely monitors the real impact of our work. Here are a few metrics we’ve collected:

3.5M Worth of Medical Waste Diverted

270+ Prosthetic Legs Fitted

50+ Partner Clinics

70+ Volunteers Involved
