Zach Buhler

HOMETOWN: Huntington, Ind.

Zach competed in his first Paralympic Games in Tokyo in 2021 as part of the USA Men’s Paralympic Goalball Team that finished fourth. He was one of two Paralympic rookies on the six-man team in Tokyo. Zach first started playing goalball in 2016 and the Tokyo Paralympics was his first major tournament. Since he was young, Zach always wanted to be a top-level athlete and when he lost his sight at the age of 12 he felt that was taken from him. When he found goalball he fell in love and started training to be the best he could be and hasn’t looked back.

IN HIS OWN WORDS: “My favorite thing about goalball has to be how competitive you can be with no limitations. I can be the athlete I have always dreamed of being with nothing holding me back. For years in sports after losing my sight, it was my biggest limitation. With goalball, nothing holds me back and I can be at the top of the world with hard work.”

She currently works as an accounting assistant for Turnstone Center for Children and Adults with Disabilities and is a resident athlete training at the U.S. Olympic & Paralympic Training Site in Fort Wayne, Ind.

IN HER OWN WORDS: “I love all aspects of the game. Goalball is a highly competitive sport by nature and having to wear eyeshades adds a very unique challenge. Most importantly nothing beats the camaraderie of being a part of a team sport. Goalball changed my life and I am eternally thankful for the athletes and coaches who encouraged me to play. My eyes were truly opened and my vision changed when I attended my first goalball practice. The opportunities I have been a part of due to goalball have helped guide my life in so many wonderful ways.”

Andy Jenks

HOMETOWN: Wilmington, Del.

Andy was introduced to goalball at a blind sports day in 2000 at the University of Delaware by his long-time coaches Greg Gontaryk and John Mulhern. He has competed and medaled at both domestic and international youth and men’s competitions during a career spanning two decades and counting. He earned his Ph.D. in political science & international relations from the University of Delaware in 2021 and currently works as an educational assessment specialist at UD’s Center for Teaching and Assessment of Learning. Goalball, and its associated travel, exposed Andy not only to different cultures and ways of playing the sport but also to the situations and policy structures which greatly affect the lives of people with disabilities. Andy incorporates his passion for teaching and learning into wide-ranging projects aimed at raising awareness and engaging with relevant stakeholders to create better disability policy, including work with professional organizations and universities in the U.S., and most recently facilitating a community-led disability justice conference in Zimbabwe. 

IN HIS OWN WORDS: “I like to think about goalball as more than a common language: it’s a culture. I’ve competed in 13 U.S. states, four continents, three Canadian provinces, and 13 countries so far in my career, and at every competition, regardless of how old I was, or how well I could communicate with peers from other teams, we all not only speak the game, we live for it. It’s not something I like to do, it’s a part of my identity. My favorite thing about goalball is that there are thousands of other athletes, coaches, referees, volunteers, friends, and families out there who speak this language and share the same passion for the game.”

Christian King

HOMETOWN: Virginia Beach, Va.

A native of Virginia Beach, Va., 22-year-old Christian King has been playing goalball for the past 7 years. He was introduced to the sport of goalball while attending school. His grandfather, James Wallace, is an assistant coach for the U.S. men’s team. James brought Christian to and from goalball practices as he was growing up and the game brought them closer together. Christian has been on the USA Men’s National Goalball Team since early in 2022 and his first tournament with the U.S. team was at the IBSA Goalball Americas Championships in Sao Paulo, Brazil, in February. During that event, Christian scored 6 goals in 8 games as the U.S. men’s team captured the silver medal. His next goal is to be part of a future Paralympic team for Team USA.

IN HIS OWN WORDS: “When I was growing up all I wanted to do was be in the navy and represent my country. Achieving the level of national team player was a long-term goal for me. Now that I am a part of the team, I want to be able to work toward bettering it as well as doing what I can for the goalball community in the United States.”

John Kusku

HOMETOWN: Commerce Township, Mich.

John is a math and physics teacher at the Oakland Schools Technical Campus Southwest in Wixom, Michigan. He teaches high school juniors and seniors from several different school districts in Southwest Oakland County. He is legally blind due to a degenerative hereditary eye disease called retinitis pigmentosa. He earned his master’s degree in mathematics in 2009 from Western Michigan University. John’s eight-year-old son, George, is in third grade and John’s wife, Jessica, is a teacher of children who are blind or visually impaired. John is a Paralympic silver medalist in the sport of goalball. He has worked in many mentoring roles for young people who are blind or visually impaired as well as their parents and teachers. 

IN HIS OWN WORDS: “When I was young I played sports with the kids in my neighborhood every chance I could, which was nearly every day. We played basketball, baseball, soccer, tennis, went swimming and jumped on the trampoline, but mostly we played driveway rollerblade hockey. As we got older, faster, and stronger I also got more blind. I could no longer play the way I wanted to play. If I skated as fast as I could I would usually hurt myself, hurt someone else, or break something. I had a huge hole in my life. I needed an activity that I could play as hard as I wanted. I needed something that was difficult but did not require sight. I went to the Sports Education Camp held at Western Michigan University hosted by the Michigan Blind Athletics Association in May of 1998. The first activity was a goalball tournament. I had played goalball several times before, but it was always very developmental and somewhat boring. In the first few minutes of my first game at sports camp, I played left wing down from a guy named Carl Love. I had met him before and I knew he was strong. He threw a ball down my line and I was slow to get my arms out and it blasted me in the face! Blood immediately began gushing out of my nose and I was permanently hooked on goalball. I found a sport to which I could dedicate hours of training and thinking. Even more, over the next few years of traveling the USA and Canada with my Michigan teammates, I found a new sense of independence, openness about my disability, and pride in myself and my blind peers. I stopped being ashamed of using my cane or asking for help with a visual task. I can blame goalball for almost every good thing I have ever done or had since that May day in 1998. I can’t imagine the person I would be without goalball.”

IN HER OWN WORDS: “My favorite thing about goalball is that I love having an opportunity to compete from club level to the highest level possible and nothing is in my way that I cannot control. Goalball is one of the only places where my lack of vision does not matter. My favorite goalball memory was at the 2019 Parapan American Games in Lima, Peru, when we marched in with the whole Team USA delegation at the opening ceremony.  Another favorite memory is when we won gold at the Tokyo test event in 2019.”

Shavon, also known as Shay, fell in love with goalball due to its originality. The fact that goalball was geared toward blind and visually impaired folk intrigued her.

IN HER OWN WORDS: “Goalball means a whole lot to me. It’s something that brings great joy and opportunity.”


A headshot photo of Eliana Mason

Eliana Mason

HOMETOWN: Beaverton, Ore.

Eliana is a two-time Paralympian and two-time Paralympic medalist, winning a bronze medal at the Rio 2016 Paralympic Games and a silver medal at the Tokyo 2020 Paralympics where she was the second-highest goal scorer on the U.S. team with 10 goals in seven games, good for eighth-best in the entire tournament. She has also participated in two Goalball World Championships (2014, 2018) winning gold in 2014. Most recently, Eliana was appointed as the United States Olympic & Paralympic Committee Athletes’ Advisory Council representative and to the U.S. Association of Blind Athletes Board of Directors.

IN HER OWN WORDS: “Growing up I always loved competing and partaking in competitive sports. My vision loss made it difficult to keep up with my sighted peers and compete at a level I wanted. I always found myself having to work through visual barriers, which took away from my experience of the sport, along with my ability to partake in it. Finding goalball was life-changing for me, because it was the first time ever I was on an equal playing field with my peers, and could simply be an athlete first. My vision was no longer part of the equation, and this was a very freeing and empowering feeling for me. I was able to focus on the sport, play at a high level and not have to compensate for vision loss. Having an equal playing field is incredibly important and made me fall in love with the game. Additionally, through goalball, I met other incredible athletes who were role models and mentors to me. I had a positive representation of vision loss for the first time in my life, and I learned to find confidence as a blind person. Goalball is one of the only blind sports played on a team, and it allowed me to be a part of a team. A lot of blind-friendly sports like swimming, running, rowing and biking are often solo sports. To find a team sport where my vision wasn’t a barrier motivated and empowered me to follow my athletic dreams.”

IN HIS OWN WORDS: “My favorite thing about goalball is the camaraderie and connectedness that I share with my teammates on and off the court. Goalball is not only a unique individual sport but is also very unique in that three players, all blindfolded, must know what each other is doing on the court at all times. That sense of unity is unmatched. The sport of goalball has provided me with so many different opportunities, but the most enjoyable is that I get the opportunity to travel the country and the world representing Team USA. It is incredible to see other countries and different cultures and I am glad that this sport has provided that outlet to let me experience new things and new places.”

Without goalball, I would have never found such a tight-knit community of people that are all going through life as individuals with a visual impairment, demonstrating to me just how successful and independent in life we can be.”
