Bilateral Above-Knee Amputee Bootcamp

As the coronavirus (COVID-19) continues to present itself in locations throughout the U.S., the safety and well-being of our patients and staff is of utmost concern. After careful consideration of the current situation, we have made the difficult decision to postpone the Bilateral Above-Knee Amputee (BAKA) Bootcamp, originally scheduled for May 14-16. We have rescheduled for September 17-19.  Please see more information below, and send any questions to

If you are a Bilateral Above-Knee Amputee, you can't miss out on attending BAKA Bootcamp.

Yvonne Llanes

Yvonne Llanes lost her legs to an accident in 2005, and spent the next nine years in a wheelchair. 

After attending BAKA Bootcamp in 2015, she made it a goal of to face her challenges and get up and walk! She's now an active prosthetic user.

"I'm hoping that by seeing what I'm doing and by seeing how far I've come in my journey, they can see that they can do it as well. It is possible to get up again," she said.


Nicole Grehn

After collapsing at a gas station in 2015, Nicole awoke from an induced coma to learn that both of her legs had been amputated above the knee. She attended BAKA Bootcamp in 2016, where she was inspired to regain her mobility and leave her wheelchair. 

She's been wheelchair-free since April 2016, and went back to school to become a nurse. She now volunteers as a mentor to young amputees and children with limb differences at Camp No Limits.


Pedro Pimenta, Hanger Clinic Patient Advocate

Pedro Pimenta 

A typical teenager in Brazil, Pedro studied and participated in sports with his friends, until a meningitis diagnosis in 2009 led to the amputation of all four of his limbs.

He sought advice and guidance wherever it was available, determined to live independently. Just ten months after leaving the hospital, the strength he never knew he had emerged and he gave up the wheelchair never to sit in one again. 

Today, Pedro lives independently in Florida using his prosthetics for mobility and practicality.
