Jonathan Siegrist

PROBAR® Ambassador

From: Madison, WI

Focus: Climber

What started as an interest eventually developed into a passion, and that passion gradually became my beloved career. I never, ever, imagined the places and experiences that climbing would take me through. I’ve climbed in over a dozen countries across four continents, living in the dirt, in the back of cars, and random beds for too long to remember. I’ve climbed a handful of 5.15 sport routes, big walls up to 5.14a V and V14 boulder problems.


ProBar offers simple, convenient food products made with real food and ingredients I’m familiar with. I’ve been leaning on delicious ProBars for my nutrition for a very long time so it’s exciting to finally team up with this awesome brand!

When Not Adventuring

Climbing has offered me a really unique opportunity to look inside of myself, to confront ego and gifted me so much inspiration. 


My drive in climbing has been constantly evolving but one thing that has remained true throughout the last decade is my attention to using the best fuels and a plant based diet.
