Son’s Story

About Penta


Penta Medical Recycling was founded by university students in 2016 to bring affordable prosthetic care to low-and middle-income countries while repurposing what would otherwise be considered medical waste in the United States.

This idea came out of the realization that 85-95% of the world’s 100 million amputees lack access to proper prosthetic care and equipment while hundreds of thousands of functional but slightly outdated prostheses are being replaced and discarded in the United States every year.

At Penta, we found that we could resolve these two problems simultaneously by collecting and repurposing used prosthetic and orthotic 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 thrive back to amputees all over the world.

Penta Medical Recycling formally incorporated as a 501(c)(3) nonprofit organization in 2018, and has since turned into a global operation working with government health organizations, private and public healthcare institutions, and other nonprofit groups based in the US and overseas. Penta’s operations have expanded to 16 different countries across 6 regions of the world and continues to explore opportunities for expansion. 


To repurpose high-quality, used prosthetic limbs discarded in the US and provide them to amputees in need in low-and-middle income countries, helping them regain physical, social, and economic mobility.


Penta aims to become the go-to resource for the collection of discarded and used prosthetic and orthotic devices, ensuring that valuable equipment doesn’t go to waste and mobility can be restored to thousands of people around the world.

Global Mobility Ambassadors

Penta’s GMA team is a network of passionate individuals helping to spread awareness of Penta’s mission and helping the amputee community through representation & advocacy. The members represent a diverse range of age, background, artistic & athletic interests, abilities, & geographic locations to better engage the many groups that make up the global amputee community. We are fortunate to have this great team and invite you to read about our ambassadors and how they advance our mission below: 

Abriel Bentley - Scottsdale, AZ


Abriel “Abri” Bentley was diagnosed with Ewing Sarcoma (a form of bone cancer) at age 7. After 17 rounds of chemo, an unsuccessful limb salvage surgery which led to bone removal, and a decision to amputate rather than attempt another limb salvage, Abri has been cancer-free for years. Now 12 years old, Abri loves to dance and ride her electric bike, which she won after participating in Penta’s Dance 4 Mobility challenge earlier this year.

Alexander Allen Hellander - Löddeköpinge, Sweden


Alex Helander, 30, hails from Sweden and is a double below-the-knee amputee, but his limb loss does not define him. He’s a devoted husband and father of two, school teacher and athlete, excelling in sit-ski. Alex additionally participated in Penta’s Dance 4 Mobility challenge, submitting a video showing off his dance moves.

Alex Schwartz - St. Louis, MO


After being born with rare birth defects, Alex Schwartz, 25, had a double foot amputation and has grown to become a major influencer in the amputee world, with a successful YouTube channel and social media following where he educates his fan base about life as an amputee. Alex has prior ties to Penta through his participation in the organization’s Dance 4 Mobility challenge that garnered dance videos from both the able and disabled communities.

Chase Merriweather - Blue Bell, PA


Chase Merriweather, 12, is a quadruple amputee sepsis survivor who continues to defy limb loss with his unbelievable tenacity, athleticism and team spirit. He competes in many adaptive sports competitions year round and recently won gold at Move United Sports competition in 2021. Penta has been the proud recipient of Chase’s limb donations, which have already gone on to give others mobility as far away as Liberia. 

Jen Bricker - Los Angeles, CA


Jen Bricker, 33, is a renowned acrobat, gymnast and aerialist whose incredible story of athleticism despite being born without legs captivated the world. Her memoir is a New York Times bestseller and she travels the globe today giving inspirational talks. Jen is the subject of a moving short film and dance video as part of Penta’s Dancing with Disability program.

Kendra Herber - Monroe, OH


Kendra is a single leg amputee who lost her leg at the age of 2 due to a physical deformity. However, Kendra has never allowed her disability to limit her in any way. She leads an active life as a mother to two young daughters, fashion model and High School English teacher. Last year she published her inspiring autobiography, WHOLE: A Leg Up On Life. Kendra, as a fierce competitor has competed in several triathlons to date reminding us that limb loss stigmas are to be shattered.

Mary Johnson - Sands Point, NY


Mary is an above the knee amputee and partial hand amputee due to a traumatic injury. At the time of her injury she was a public school English teacher and middle school running club coach. She continued teaching English for a few years after her amputation and has also continued to run. Recently, she has set her goals on helping others navigate the complex legal and healthcare system which one faces as a disabled person and is attending law school.

Pollyanna Hope - Hertfordshire, UK


Pollyanna Hope is a reknowned 16-year-old ballet dancer from Hertfordshire, England. Struck by a bus at just 2-years-old, Pollyanna’s 21 operations and amputated leg have not stopped her from pursuing her dreams as a dancer, and she is one of the first ballerina’s to use an “en-pointe” prosthesis. In 2021, Pollyanna was admitted to the English National Ballet Youth Company, and she plans to continue training in both ballet and contemporary dance, pursuing a career as a professional dancer. Penta is thrilled to work with Elizabeth’s Legacy of Hope in Liberia, an organization whose mission to help amputee children was inspired by Pollyanna’s experience. 

Reggie Showers - Philadelphia, PA


Reggie is a bilateral, below–knee amputee and is an advocate and certified peer visitor.  He is also a world champion motorcycle drag-racer, inspirational speaker, accomplished pilot, certified snowboard instructor, and year-round volunteer at community events. It doesn’t stop there, as Reggie is a proud ambassador for College Park Industries and their high-quality prosthetic equipment, which he helps to collect for Penta. 

Sian Lord - Leicester, UK


Sian Lord lost her leg when she was hit by a yellow cab near Rockefeller Center shortly after arriving in New York City for a holiday in 2013, and later had to have her leg amputated. Since then Sian has become an international amputee motivational speaker, influencer as well as a positive self image advocate and fashion model. She and her husband have a daughter and reside in the UK.

Son Vu - Ho Chi Minh City, Vietnam


Son was one of Penta’s very first recipients, and at 24 years old, he has already become a triumphant business owner and artist thanks to the mobility granted to him by his prosthesis. Beyond his bridal boutique and photography business, Son is also an avid break-dancer and singer, both of which he does to raise money for charity. Son told us that he “would not have accomplished 90% of what [he has] accomplished today if it were not for Penta’s support.
