Douglas Katz – Guest Bio for CrazyFitnessGuy Podcast

I'm Doug Katz—a West Point grad, lifelong athlete, and disabled Army veteran. Health and fitness have always been part of who I am, but decades of football, rugby, martial arts, and military service left their mark. When injuries made even basic tasks harder, I didn’t want to give in—I wanted a better way.

That led me to create NULU, an adaptive kitchen knife built for people like me—those dealing with arthritis, aging, injury, or neurological challenges like MS or Parkinson’s. I didn’t set out to reinvent the knife, but I ended up doing it anyway. We designed NULU from the ground up to reduce strain, improve safety, and give people their independence back in the kitchen.

I’m here to talk about what happens when your body changes but your drive doesn’t—and how innovation, grit, and a little creativity can help you keep moving forward.
