I Wasn’t Weak. I Was Undiagnosed

I spent years pushing my body as a swimmer — through college and even into my dream job as a Division I coach — without knowing I was battling cystic fibrosis all along.

I wasn’t supposed to make it this far.

I was born six weeks early, to parents who weren’t ready. They fought constantly, partied hard, and eventually split up. My sister went with my dad, and I stayed with my mom — even after my dad evicted us. From that point on, it was chaos. I was the kid working at 14 and drifting through life without much guidance.

I didn’t find stability until I found the pool.

It started as a lifeguard job. But something about the water clicked with me. I started swimming — slowly at first, but then all in. I had structure. I had goals. I pulled my grades up, fought for a fifth year of high school just to stay on track, and found a way forward. I even met my future wife because of the sport. She was someone who saw me for more than the rough edges. She believed in me before I believed in myself.

I chased swimming hard. Went to college. Trained like hell. I became a sprint freestyler — my main focus was the 50- and 100-yard races. I trained to reach a 20.34-second 50-yard freestyle and a 45.05-second 100-yard freestyle. I competed at NCAAs and U.S. Winter Nationals. After college, I continued to train, and in 2016, I missed the U.S. Olympic trial cut by only 0.35 seconds. I achieved all of this even though I didn’t even start swimming until junior year of high school.

But all that time, something wasn’t right.

I was always thin. Always coughing. I cleared my throat constantly after races, during workouts, even while I was coaching. I didn’t gain muscle or weight like the other sprinters. My recovery was always a little behind. But I brushed it off. I figured that was just my body.

Then COVID-19 happened and everything got worse.

After getting COVID, my health started spiraling. I couldn’t train consistently. I kept getting sick, fatigued, and inflamed. My sinuses were a mess. I started having anxiety, or what I thought was anxiety — chest tightness, insomnia, and lightheadedness. I went from working out daily to barely doing anything. For over two years, I lived like that. Burned out, confused, and frustrated. Doctors told me it was stress and anxiety driving my sickness. They prescribed meds that didn’t help. I tried everything.

And it didn’t just affect my personal life. It nearly destroyed my career.

At the time, I was the head swim coach at a Division II school. I built a powerhouse program and had one of the most successful tenures in school history. But my body was falling apart. I couldn’t keep up. I was exhausted all the time, getting sick constantly, and still had no real explanation for any of it. I kept pushing, but my health kept declining. I was stuck.

Eventually, I got let go. The termination felt like a punch in the gut; not just because I loved that job, but because deep down, I knew I wasn’t just “struggling” or “burnt out.” Something was actually wrong. But I didn’t have proof yet.

Until I figured it out myself.

After landing my dream job coaching at a Division I school, I noticed something weird — my hands would wrinkle instantly in water. Not just prune up a little, but full-on aquagenic wrinkling within seconds. I’d never really thought about it before, but it stuck with me. This isn’t normal. I started digging. Researching. Reading medical papers. And every trail led to the same place: cystic fibrosis. I went to my doctor and said, “I want a sweat test. I think I have CF.” They looked at me like I was reaching, but I wasn’t wrong.

A few tests later, the diagnosis was official — I had cystic fibrosis. At 33 years old.

I felt a wave of emotions... relief, grief, anger, clarity. All these symptoms weren’t just in my head. It wasn’t burnout. It wasn’t anxiety. It was a disease. It had a name. And I finally uncovered it. I started Trikafta immediately, and everything changed.

Within days, I was purging mucus I didn’t even know was in me. Within weeks, I was breathing through my nose (which I’d never naturally done before). My sinuses cleared. My lungs opened up. I could move again. My sleep improved. For the first time in my life, I felt like my body was working with me instead of against me.

It’s made me reflect on everything I accomplished before this diagnosis, both as an athlete and a coach, and just how much I’d been carrying without knowing it. I wasn’t just overcoming a tough background. I was unknowingly training with a chronic genetic disease the entire time.
 

Since my diagnosis, I’ve become deeply committed to making sure no one else walks blindly through the same fog I did. I now serve on the advisory board for my local CF clinic, and I’m volunteering with the Cystic Fibrosis Foundation to share my story … not for sympathy, but for awareness, action, and advocacy.

I’m also proud to be receiving care through West Virginia University Medicine, where I’ve finally found a care team that listens, supports, and collaborates with me. It’s made a world of difference having experts who treat me like a partner in my own health.

This journey isn’t about what I’ve lost. It’s about what I’m building now — a path forward for others like me who were told it was “just in their head.” Because it wasn’t. And we’re not alone anymore.
