Yvonne Llanes, Bilateral AboveKnee Patient Advocate

Yvonne Llanes

My name is Yvonne Llanes, and I am from San Antonio, Texas. I am 48 years old, and have been a double above knee amputee for 11 years. Before my amputations, I was an elementary school principal, and taught for 18 years prior to that. I was a busy mother of 4 and the wife of an active duty Marine. On September 18, 2005, while at an outdoor shopping mall in Yuma, Arizona, I was loading packages into the back of my vehicle.

Unbeknownst to me, a driver high on methanphetamines hit me from behind, pinning me between my vehicle and his, severing my legs upon impact. Once the responders in the area were able to separate the vehicles, I landed on the hot asphalt. Without legs to support me, I fell on my backside and received 2nd degree burns from the asphalt and the radiator fluid which had erupted from the crash.

After being in the hospital and a rehab facility for months, I was finally able to go home. However, I struggled with my limitations for many years, only leaving my wheelchair for transfers and for occasional physical therapy sessions. I had to have several revision surgeries throughout this time, which only left me sinking deeper into a dark hole. I was feeling terrible about myself when my social worker from Hanger Clinic told me about a bootcamp offered through them. I had been a Hanger Clinic patient since 2011, so I told myself I would register for the bootcamp and give it a chance.

After attending Hanger Clinic's bootcamp in Oklahoma City in April of 2015, my life as an amputee changed forever. I decided it was time to make a major mobility change in my life, so I left my wheelchair behind on June 20, 2015 and decided to become a full-time prosthetic user.

After seeing all the fantastic people at bootcamp and becoming inspired by their strength and capabilities, I made it a goal of mine to face my challenges and get up and walk! Nine years and seven months in a wheelchair had been enough! I have also made it a goal of mine to return to bootcamp every year henceforth. I have had so much support from my Hanger Clinic family, my amputee family, and the general community, and in turn am eager to help and support others who may be dealing with their own obstacles and challenges.

Yvonne has pledged to attend the bilateral above-knee bootcamp every year to help and support others who are dealing with their own obstacles and challenges. 

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


Cameron Clapp, Bilateral AK Patient Advocate


​Cameron Clapp

On September 15, 2001, four days after the tragedy of 9/11, 15-year-old Cameron Clapp experienced his own devastating tragedy – after an evening of underage drinking with his twin brother, Clapp was struck by a train and lost both legs and his right arm in the accident. He was told by members of the medical community that he would never walk again, but Clapp proved them wrong just five months after the accident by walking independently with two prosthetic legs.

Showing that spirit and determination can conquer even the worst odds, Clapp made a remarkable physical and emotional recovery. His perspective changed; he valued life in a way that only someone who brushed death could. Unfortunately, his identical twin brother, Jesse, continued to experiment with drugs. In January 2008, Clapp lost his best friend and twin brother to a drug overdose.

Now at 30-years-old, Clapp travels the country on two microprocessor-controlled legs sharing his incredible survival story with fellow amputees, teenagers, and members of the medical community. Clapp’s message is simple – give your patients hope; life is about overcoming obstacles, setting goals, never giving up, making the right decisions, and not using drugs and alcohol. 


​Nicole Grehn

On June 28, 2015, I suddenly collapsed in a gas station in a small Northern Wisconsin town, which was thankfully across the street from a hospital. A nearby ambulance came to my rescue in about 3 minutes, which was amazing timing considering my condition. Over the course of 36 hours, I flat lined 78 times, was induced into a coma, and was put on a machine to keep my heart beating. During my 9 day coma, my heart was only pumping at 10% and thus my limbs were not getting enough blood perfusion. To prevent septic shock and save my life, the doctors had to amputate both of my legs above the knee. That procedure saved my life and within a day, my heart starting pumping at 40% and four days later they woke me from my coma. I was a healthy, active 24 year old with no symptoms of heart failure. Three months later I found out that I have a genetic mutation in my heart for sudden cardiac death, called CPVT. Thankfully, I now have a defibrillator to act on my heart if I ever go into a bad rhythm again.

After this life changing trauma, I found Hanger Clinic and their amazing bootcamp for bilateral above knee amputees. On April 6th, 2016 I was inspired to leave my wheelchair after hearing other amputees’ amazing testimonies. I have been wheelchair free ever since, and have become part of a new family - my amputee family.

I am pursuing my education at Marquette University to get my Masters of Science in Nursing, and graduate in December of 2017. I'll be pursuing my Doctorate of Nursing Practice, in order to work as a nurse practitioner in the physical medicine and rehab field. I also mentor young amputees and children with limb differences at Camp No Limits. I want to help others in the amputee community through volunteering and my profession.

If someone came up to me today and said "Nicole, I will give you your legs back, but you will not remember the people, nor the experiences you have had after your amputation," my response would be “NO”. I would never take my legs back at the expense of the friendships I have made, the love I have received, and my clear calling and purpose in life. I wouldn't trade that for anything.

Wendy Glissmeyer, CPOWendy Glissmeyer, CPO

Wendy realized her desire to be a Prosthetist after volunteering at Shriner's Hospital for Children in Utah. She attended California State University, Dominguez Hills in 2005, Wendy completed her prosthetic residency with Shriner's Hospital for Children, and then began working with Hanger Clinic in 2007 in Salt Lake City. As a pediatric specialist enjoys every aspect of care for this uniquely active population. Wendy learned a variety of new skills required to fit, communicate with and educate adults living with limb loss compared to children. She strives to bring the energy and excitement of working with youth to the adults in her current clinic. She is often found smiling and laughing with patients, or taking a walk around the building to "test things out in the real world." She finds the biggest challenges adults with amputations face are their own fears or preconceived ideas about adapting to life with a prosthesis

She is an educator at the University of Utah, Hanger Clinic, and organizer of Utah Hanger Clinic Running/Mobility Clinics.  She finds great satisfaction in helping clients learn to really thrive in life after their basic recovery from illness or injury.

Pedro Pimenta, Hanger Clinic Patient Advocate

Pedro Pimenta

In December 2017, Pedro accepted a position at Hanger Clinic as the AMPOWER National Coordinator. He now manages the the AMPOWER Amputee Peer Support Group which consists of a nationwide network of trained peer mentors who have successfully recovered and rehabilitated following an amputation. Mentors are available to speak face-to-face, over the phone, via skype or facetime, through e-mail or through our private, password-protected online web community.

A typical teenager in Brazil, Pedro studied and participated in sports with his friends. He enjoyed an extensive social life and healthy lifestyle until, suddenly, he began to feel sick on September 11, 2009. No one will forget where they witnessed the tragic events of September 11th, but this day is particularly emotional for Pedro and his loved ones as he was admitted to the hospital to fight for his life.

Pedro had contracted a fatal form of meningitis that soared through his bloodstream. With slim chances that he would survive, nearly one hundred of his closest friends and family took turns saying their goodbyes. Miraculously, Pedro left the hospital alive six months and two comas later, but in exchange, had all of his limbs amputated above the elbows and knees.

People destined him to a life in the wheelchair, saying that no other amputee in his situation had successfully lived a life on prosthetics. Although frightened by this discouragement, Pedro knew that he did not want to spend the rest of his life with a wheelchair by his side.

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. While attending college, he inspires anyone he comes across, and shows them the strength that exists in us all. Many people today are stressed at work, dissatisfied with their lives, and generally unhappy. Pedro demonstrates to these people that we all have the power to overcome any situation in life.
