Sebastian Brannen
About me!
Hi everyone!
My name is Sebastian Brannen. I’m 23 years old, I have Autism my superpower, and I’m a voice actor on the rise, a marathoner, half-marathoner, Ironman finisher, and a proud member of the Doug Flutie Jr. Foundation for Autism.
And guess what? On January 10th, 2026, I’ll be kicking off my year by running the Disney Half Marathon in Orlando with the Doug Flutie Jr. Foundation team!
Running has changed my life in ways I could never have imagined. It has helped me understand who I am, build confidence, and find my voice in a world that sometimes felt overwhelming. Every run clears my mind, strengthens my heart, sparks creativity, and reminds me that I am capable of so much more than I ever thought. Running has taught me courage, resilience, and belief in myself and it has helped me inspire others to push for their dreams too.
Since joining the Flutie Foundation, my world has grown even bigger. I didn’t just run the Boston Marathon I made friends who believe in me, cheer for me, and encourage me to reach higher. They helped give me the confidence to attend college, and today I’m proud to be a student at Santa Fe College. The foundation didn’t just support me… they helped me believe in possibilities.
Now, I’m running this race not just for myself, but to raise awareness, acceptance, and opportunities for everyone in the autism community.
But I can’t do this alone I need your help.
This half marathon is raising funds for the Doug Flutie Jr. Foundation, which works every day to empower people and families affected by autism. Your donation helps create programs, support independence, and amplify voices like mine.

Truly, any amount counts. It’s not about how much you give… it’s about showing up, caring, and being part of something meaningful.
Even if you don’t have a family member with disabilities, chances are you know someone, love someone, or have a friend who does. Your support helps create a world with more acceptance, more understanding, and more opportunities for people like me.
I’m genuinely looking forward to seeing your name on the donor list. Your support means the world to me, and together we can make a powerful impact.
