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 12 years. Before my amputations, I was an elementary school principal and taught for 18 years prior to that. I was a busy mother of four 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 methamphetamines hit me from behind, pinning me between my vehicle and his, severing my legs upon impact. Once the responders were able to separate the vehicles, I landed on the hot asphalt. Without legs to support me, I fell on my backside and received second-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 boot camp offered through them. I had been a Hanger Clinic patient since 2011, so I told myself I would register for the boot camp and give it a chance.

After attending Hanger Clinic's boot camp 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 boot camp 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 boot camp every year henceforth. I have had so much support from my Hanger Clinic family, my amputee family, and the general community, and in turn I am eager to help and support others who may be 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 can see that they can do it as well. 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, Cameron was struck by a train and lost both legs and his right arm. He was told by members of the medical community that he would never walk again, but Cameron 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, Cameron 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, Cameron lost Jesse, his best friend, to a drug overdose.

Now at 30 years old, Cameron travels the country on two microprocessor-controlled legs, sharing his incredible survival story with fellow amputees, teenagers, and members of the medical community. His 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. An ambulance came to my rescue in about three minutes, which was amazing timing. 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 nine-day coma, my heart was only pumping at 10 percent 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 percent and four days later they woke me from my coma. I was a healthy, active 24-year-old woman 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 boot camp for bilateral above-knee amputees. On April 6, 2016, I was inspired to leave my wheelchair after hearing other people's amazing testimonies. I have been wheelchair-free ever since, and have become part of a new family – my amputee family.

I graduated in December 2017 from Marquette University with a Master's of Science in nursing. I'll be pursuing my Doctor 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.

After overcoming several challenges, including surviving cancer, drug addiction, losing both of his legs above the knee, and learning how to walk again, Matthew Brewer is finally on a path to achieving his goals he never thought were possible. Being featured on "The Doctors" show three times has played a huge factor in Matthew's recovery. He was offered alternative treatments for phantom pain, and the blessing of being able to be pain free without the use of opiate pain killers and receiving Transcranial Magnetic Stimulation (TMS) for depression. Matthew was also provided an opportunity to attend the 2017 Bilateral Above-Knee Amputee Bootcamp in Oklahoma City where he met Kevin Carroll, MS, CP, FAAOP/D.

Matthew resides in Huntington Beach, California, and graduated from Marina High School in 1993.
