“The stigmas of the past will not take away the voices of the future.” My parents found out in 1985 via amnio that I was going to be born with Klinefelter syndrome (non-mosaic 47 XXY). I was told at 9 years old. The first time I googled Klinefelter syndrome was in June of 2017, a few months later I started the “Living with XXY” Youtube channel. In November of 2019 we became an official NonProfit. I currently live in San Diego, CA. Before Living With XXY, I was a Chef for 10 years, graduating from the CIA in 2007. I have had multiple careers since, including a freelance action sports photographer. I love spending time with my family, snowboarding, camping, and hiking.

Hi, I don’t have Klinefelter syndrome, but my friend Ryan does. Since finding out about Ryans’s condition I have been wanting to help him with his efforts to make change. Living with XXY is my opportunity. Being part of this team is my opportunity to use my professional skills as a photographer and filmmaker. I work with many diverse companies including Getty Images, RedBull, ESPN, and National Geographic. In my free time, I enjoy spending time with my family snowboarding and mountain biking.

I’m a professional writer and author, as well as the mom of a toddler with XXY. When I’m not helping folks share their stories about living with XXY, I keep busy helping people create amazing resumes, writing content for websites, or working on my second novel. I live in a small town in rural Maine with my son, husband, a tortoiseshell cat who’s the boss of us all, and a black lab. We also have a backyard flock of seven chickens. It feels wonderful to be apart of this amazing Klinefelter Syndrome team and helping this amazing community grow. I look forward to working with you and your family. If you have any questions, please email me.

I am so excited to learn more about the community and create resources that will empower men with Klinefelter syndrome and their families. For seven years I’ve worked in higher education. I also worked with non-profit organizations teaching, researching, creating content, and advocating for people’s best interests. When I am not working, I am chasing around my toddler, gardening, knitting, or watching a random TV show.

From a young age, Kimberly Walker wanted to be a writer, but the path to get there was winding. After working for years as a restaurant manager, she moved to sales and marketing. She found herself working in ad sales for the Galveston County Daily News. Figuring this was the best time to seize the moment, she walked into her boss’s office and asked for a chance to do some writing, in any capacity.


Gareth Landy
Gareth LandyIreland Advocate
Hello everyone, my name is Gareth Landy, and I live in Ireland. I was diagnosed as XXY when I was 37 years old when trying to start a family with my wife, Anna. We now have the most amazing donor-conceived twins who take up pretty much all of our time and focus :) My background is in video production and photography, and until recently, I ran a very successful wedding film business. I like to take on significant challenges, so I cycled the length of Ireland to raise money for children with cancer and have run the Dublin Marathon three times. These days I love to take images of my children with my trusty prime lens, give tips to tourists on things to see in Ireland, and lastly, do some running.

Hi! I am Shelby. I am married to my high school sweetheart Paul. We have a 14 month old son named Paxton! We are from Pittsburgh, Pa. Pax is the best thing that ever happened to us! My NIPT test was normal and we ended up finding out at 4 months old that Pax has xxy. We found out when we went to a genetic doctor to follow up on an infection Pax had early on. Pax is already so loving and laid back. He loves animals, being outside, and trucks! I am a registered nurse at a primary care doctors office.I truly love helping people! I am use to being an advocate for my patients and I can’t wait to be an advocate for livingwithxxy! In our free time our family likes to hang out, watch hockey, and take Pax to activities!

I am a 28 year old mom from Michigan. I live here with my husband and XXY baby, Elijah! We received prenatal testing that showed Eli may have Klinefelter’s. When he was born in March of 2020, his diagnosis was confirmed with cord blood testing. My job allows me to be with Eli most of the time, and we plan to homeschool in the future. When I’m not on mom-duty, I love live concerts (pre-COVID), good coffee and shamelessly watching guilty pleasure shows like 90 Day Fiance and The Office!

G’day, I’m Geoff and I live in Victoria, Australia. My wife and I have been married for 12 years and we have a kind hearted 9yo Border Collie named Kargi – which means Brother in Aboriginal. I’m a chef by trade and last year started my own business: Krucky’s Fine Foods. I love to create delicious chutneys and jams, as well as Granola and a range of gourmet crackers. I also run a successful Sourdough Bread business from home and am expanding into an 100yo wood fired bakery over the next few months. Part of my dream for the business is to be able to mentor and train others in my craft.

Nature is my therapy, when I am feeling stressed with work or life in general, you can find me in the mountains. My favorite naturalist is John Muir. One of his quotes is on a bumper sticker on my car, “The Mountains Are Calling, I Must Go.” Another Quote “Keep Close to Nature’s Heart…and break clear away, once in a while, and climb a mountain or spend a week in the woods. Wash your spirit clean.”
I am a published iphoneographer. I have been published and interviewed for my landscape photography using my iPhone.

Years ago I came to the United States from Poland to be an Au Pair. I had the chance to mesh my Polish upbringing with American culture and apply it to child care. There’s no better feeling than excitement and pride watching children grow up. I learned about XXY upon meeting Ryan when I moved to San Diego. I am happy to be apart of this amazing Klinefelter syndrome team. I grew up dancing to Frank Sinatra, attended University for International Business and I love eating napoleons (yum!). I spend my free time working on advanced yoga techniques, hiking, and paddleboarding in beautiful San Diego.
