Let reintroduce you to Colleen Dalaigh , co-owner of Underdog Martial Arts | Asheville BJJ • Kickboxing .
10th Planet Brown Belt.
Fit to Fight Defensive Options Black Belt.
Self defense expert and founder of Guerrera, Washington DC’s number one women and femmes self defense program.
Boss Bitch.
She also happens to be my wife. I know I know, I’m a super lucky (and grateful guy).
Before she met me, she was already a badass on her own.
She hit the competition mats running and by the time she got her blue belt from Zach Maslany , she was competitive in purple belt divisions. She knew how to do a twister before I even started paying attention to 10th Planet. Her name was on the table for one of the most up and coming female competitors in the Northeast. She was making waves, and competed in invitationals with world champions.
She IS that girl.
Through Guerrera she had already coached hundreds of women and femmes before we met. Now that number is in the thousands.
In 2023 she suffered a spinal injury that ended her competition career, and by the end of that year, the idea of Underdog was born. Now she coaches 6 days a week, teaching striking, jiujitsu, self defense and fitness, ushering in the next wave of people.
She’s taught me so much on the mats. She’s helped me become a better coach. She’s helped me look at things from different perspectives.
She’s a better striker and has more striking competitions under her belt that I ever will. She has better business acumen than me. And she’s the reason Underdog exists.
Just in case you didn’t know who she is.
This. Is. her.
